This attribute is going to represent number of queues for
multique vhost network interface. This commit implements XML
extension part of the feature and add one test as well. For now,
we can only do xml2xml test as qemu command line generation code
is not adapted yet.

2a58d07654 conf: add 'sharePolicy' attribute to graphics element for vnc
-vnc :5900,share=allow-exclusive
allows clients to ask for exclusive access which is
implemented by dropping other connections Connecting
multiple clients in parallel requires all clients asking
for a shared session (vncviewer: -shared switch)

 -vnc :5900,share=force-shared
disables exclusive client access.  Useful for shared
desktop sessions, where you don't want someone forgetting
specify -shared disconnect everybody else.

 -vnc :5900,share=ignore
completely ignores the shared flag and allows everybody
connect unconditionally

VirtualBox driver is built into libvirtd, instead of libvirt.so
This change avoids the VirtualBox GPLv2-only license causing

GPLv2-or-later license.

a7c4202cdd qemu: Support discard for disk
QEMU introduced "discard" option for drive since commit a9384aff53,

<...>
@var{discard} is one of "ignore" (or "off") or "unmap" (or "on") and
controls whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
requests are ignored or passed to the filesystem.  Some machine types
may not support discard requests.
</...>

This patch exposes the support in libvirt.

QEMU supported "discard" for "-drive" since v1.5.0-rc0:

% git tag --contains a9384aff53
contains
v1.5.0-rc0
v1.5.0-rc1

So this only detects the capability bit using virQEMUCapsProbeQMPCommandLine.

ccff335f83 Support for static routes on a virtual bridge
network: static route support for <network>

This patch adds the <route> subelement of <network> to define a static
route.  the address and prefix (or netmask) attribute identify the
destination network, and the gateway attribute specifies the next hop
address (which must be directly reachable from the containing
<network>) which is to receive the packets destined for
"address/(prefix|netmask)".

These attributes are translated into an "ip route add" command that is
executed when the network is started. The command used is of the
following form:

  ip route add <address>/<prefix> via <gateway> \
               dev <virbr-bridge> proto static metric <metric>

Tests are done to validate that the input data are correct.  For
example, for a static route ip definition, the address must be a
network address and not a host address.  Additional checks are added
to ensure that the specified gateway is directly reachable via this
network (i.e. that the gateway IP address is in the same subnet as one
of the IP's defined for the network).

prefix='0' is supported for both family='ipv4' address='0.0.0.0'
netmask='0.0.0.0' or prefix='0', and for family='ipv6' address='::',
prefix=0', although care should be taken to not override a desired
system default route.

Anytime an attempt is made to define a static route which *exactly*
duplicates an existing static route (for example, address=::,
prefix=0, metric=1), the following error message will be sent to
syslog:

    RTNETLINK answers: File exists

This can be overridden by decreasing the metric value for the route
that should be preferred, or increasing the metric for the route that
shouldn't be preferred (and is thus in place only in anticipation that
the preferred route may be removed in the future).  Caution should be
used when manipulating route metrics, especially for a default route.

Note: The use of the command-line interface should be replaced by
direct use of libnl so that error conditions can be handled better.  But,
that is being left as an exercise for another day.

ada14b86cc Add support for storage format in FS <driver>
Extend the <driver> element in filesystem devices to
allow a storage format to be set. The new attribute
uses 'format' to reflect the storage format. This is
different from the <driver> element in disk devices
which use 'type' to reflect the storage format. This
is because the 'type' attribute on filesystem devices
is already used for the driver backend, for which the
disk devices use the 'name' attribute. Arggggh.

Anyway for disks we have

   <driver name="qemu" type="raw"/>

And for filesystems this change means we now have

   <driver type="loop" format="raw"/>

5c811dcec5 conf: Generic XMLs for scsi hostdev
An example of the scsi hostdev XML:

    <hostdev mode='subsystem' type='scsi'>
      <source>
        <adapter name='scsi_host0'/>
        <address bus='0' target='0' unit='0'/>
      </source>
      <address type='drive' controller='0' bus='0' target='4' unit='8'/>
    </hostdev>

Controller is implicitly added for scsi hostdev, though the scsi
controller's model defaults to "lsilogic", which might be not what
the user wants (same problem exists for virtio-scsi disk). It's
the existing problem, will be addressed later.

The device address must be specified manually. Later patch will let
libvirt generate it automatically.

This only introduces the generic XMLs for scsi hostdev, later patches
will add other elements, e.g. <readonly>, <shareable>.

6b74a9f5d9 string: make VIR_STRDUP easier to use
While reviewing proposed VIR_STRDUP conversions, I've already noticed
several places that do:

if (str && VIR_STRDUP(dest, str) < 0)

which can be simplified by allowing str to be NULL (something that
strdup() doesn't allow).  Meanwhile, code that wants to ensure a
non-NULL dest regardless of the source can check for <= 0.

Also, make it part of the VIR_STRDUP contract that macro arguments
are evaluated exactly once.

(VIR_STRNDUP_QUIET): Improve contract.

c4f63ef080 conf: formatter/parser/RNG/docs for hostdev <driver name='kvm|vfio'/>
A domain's <interface> or <hostdev>, as well as a <network>'s
<forward>, can now have an optional <driver name='kvm|vfio'/>
element. As of this patch, there is no functionality behind this new
knob - this patch adds support to the domain and network
formatter/parser, and to the RNG and documentation.

When the backend is added, legacy KVM PCI device assignment will
continue to be used when no driver name is specified (or if <driver
name='kvm'/> is specified), but if driver name is 'vfio', the new UEFI
Secure Boot compatible VFIO device assignment will be used.

Note that the parser doesn't automatically insert the current default
value of this setting. This is done on purpose because the two
possibilities are functionally equivalent from the guest's point of
view, and we want to be able to automatically start using vfio as the
default (even for existing domains) at some time in the future. This
is similar to what was done with the "vhost" driver option in
<interface>.

1bf25ba249 docs: fix usage of 'onto'

0f4f5cb26d rng: tighten up domain <controller> schema
The rng schema for <controller> had been non-specific about which
types of controllers allowed which models, and also allowed the
num_queues attribute (since that hasn't been released yet, should we
rename it to "numQueues"?) and <master> subelement to be included for
any controller type. In reality, half of the models are allowed only
for type='scsi', and the other half only for type='usb', num_queues is
allowed only for type='scsi', and <master> only for type='usb'.

This patch makes a separate <group> for type='scsi' and type='usb',
with each group allowing only the appropriate model values, and
allowing num_queue and <master> only when appropriate.

<interleave> also hadn't been specified, forcing a specific order of
subelements, which should never be done. (Note that the <interleave>
had to surround the main element attributes that are in the <group>
subelements, due to one of the <group>s containing a subelement).

09d2547f96 qemu: Allow the disk wwn to have "0x" prefix
The recent qemu requires "0x" prefix for the disk wwn, this patch
changes virValidateWWN to allow the prefix, and prepend "0x" if
it's not specified. E.g.

qemu-kvm: -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,\
drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,wwn=6000c60016ea71ad:
Property 'scsi-hd.wwn' doesn't take value '6000c60016ea71ad'

Though it's a qemu regression, but it's nice to allow the prefix,
and doesn't hurt for us to always output "0x".

Attribute 'type' can be either 'scsi_host' or 'fc_host', and defaults
to 'scsi_host' if attribute 'name' is specified. I.e. It's optional
for 'scsi_host' adapter, for back-compat reason. However, mandatory
for 'fc_host' adapter and any new future adapter types. Attribute
'parent' is to specify the parent for the fc_host adapter.

1a308ee015 qemu: add support for libiscsi
libiscsi provides a userspace iSCSI initiator.

The main advantage over the kernel initiator is that it is very
easy to provide different initiator names for VMs on the same host.
Thus libiscsi supports usage of persistent reservations in the VM,
which otherwise would only be possible with NPIV.

libiscsi uses "iscsi" as the scheme, not "iscsi+tcp".  We can change
this in the tests (while remaining backwards-compatible manner, because
QEMU uses TCP as the default transport for both Gluster and NBD).

4932ef4502 rng: restrict passthrough names to known-good files
There is some controversy[1] on the qemu list on whether qemu should
have ever allowed arbitrary file name passthrough, or whether it
should be restricted to JUST /dev/random and /dev/hwrng.  It is
always easier to add support for additional filenames than it is
to remove support for something once released, so this patch
restricts libvirt 1.0.3 (where the virtio-random backend was first
supported) to just the two uncontroversial names, letting us defer
to a later date any decision on whether supporting arbitrary files
makes sense. Additionally, since qemu 1.4 does NOT support
/dev/fdset/nnn fd passthrough for the backend, limiting to just
two known names means that we don't get tempted to try fd
passthrough where it won't work.

fa16c80f52 doc: schema: Add basic documentation for the virtual RNG device support
This patch documents XML elements used for (basic) support of virtual
RNG devices.

In the devices section in the domain XML users may specify:

For the default 'random' backend:
  <devices>
    <rng model='virtio'>
      <backend model='random'>/dev/urandom</backend>
    </rng>
  </devices>

For the slightly more advanced EGD backend:
  <devices>
    <rng model='virtio'>
      <backend model='egd' type='udp'>
        <!-- this is a definition of a character device -->
        <source mode='bind' service='1234'/>
        <source mode='connect' host='1.2.3.4' service='1234'/>
        <!-- or other valid character device configuration -->
      </backend>
    </rng>
  </devices>

For the planned random daemon/pool:
  <devices>
    <rng model='virtio'>
      <backend model='pool' pool='poolname'>class</backend>
    </rng>
  </devices>

to enable the RNG device for guests.

0b73a763f3 use client id for IPv6 DHCP host definition
Originally, only a host name was used to associate a
DHCPv6 request with a specific IPv6 address.  Further testing
demonstrates that this is an unreliable method and, instead,
a client-id or DUID needs to be used.  According to DHCPv6
standards, this id can be a duid-LLT, duid-LL, or duid-UUID
even though dnsmasq will accept almost any text string.

Although validity checking of a specified string makes sure it is
hexadecimal notation with bytes separated by colons, there is no
rigorous check to make sure it meets the standard.

Documentation and schemas have been updated.

Any such defined option will result in a dhcp-option=<number>,"<value>"

Currently, DHCP options can be specified by number only and there is
no whitelisting or blacklisting of option numbers, which should
probably be added.

c1509ab47e qemu: escape ipv6 for rbd network disk hosts
Hosts for rbd are ceph monitor daemons. These have fixed IP addresses,
so they are often referenced by IP rather than hostname for
convenience, or to avoid relying on DNS. Using IPv4 addresses as the
host name works already, but IPv6 addresses require rbd-specific
escaping because the colon is used as an option separator in the
string passed to qemu.

Escape these colons, and enclose the IPv6 address in square brackets
so it is distinguished from the port, which is currently mandatory.

828820e2d3 schemas: Add schemas for more CPU topology information in the caps XML
This patch adds RNG schemas for adding more information in the topology
output of the NUMA section in the capabilities XML.

The added elements are designed to provide more information about the

A demonstration of supported XML added by this patch:
<capabilities>

    <topology>
      <cells num='3'>
        <cell id='0'>
          <cpus num='4'> <!-- this is node with Hyperthreading -->

The socket_id field represents identification of the physical socket the
CPU is plugged in. This ID may not be identical to the physical socket
ID reported by the kernel.

The core_id identifies a core within a socket. Also this field may not
accurately represent physical ID's.

The core_id is guaranteed to be unique within a cell and a socket. There
may be duplicates between sockets. Only cores sharing core_id within one
cell and one socket can be considered as threads. Cores sharing core_id
within sparate cells are distinct cores.

The siblings field is a list of CPU id's the cpu id's the CPU is sibling
with - thus a thread. The list is in the cpuset format.

55bfd020d8 qemu: Support ram bar size for qxl devices
Adds a "ram" attribute globally to the video.model element, that changes
the resulting qemu command line only if video.type == "qxl".

<video>
  <model type='qxl' ram='65536' vram='65536' heads='1'/>
</video>

That attribute gets a default value of 64*1024. The schema is unchanged
for other video element types.

The resulting qemu command line change is the addition of

-global qxl-vga.ram_size=<ram>*1024

or

-global qxl.ram_size=<ram>*1024

For the main and secondary qxl devices respectively.

The default for the qxl ram bar is 64*1024 kilobytes (the same as the
default qxl vram bar size).

3d1596b048 Introduce an LXC specific public API & library
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.

The actual APIs are

  int virDomainLxcOpenNamespace(virDomainPtr domain,
                                int **fdlist,
                                unsigned int flags);

  int virDomainLxcEnterNamespace(virDomainPtr domain,
                                 unsigned int nfdlist,
                                 int *fdlist,
                                 unsigned int *noldfdlist,
                                 int **oldfdlist,
                                 unsigned int flags);

which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.

NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

This means you could not use a ':' character inside those comments
without ill effects.

Now, a key must consist solely of alphanumeric characters, '_' or '.'.

aae0fc2a92 Add support for <hostdev mode="capabilities">
The <hostdev> device type has long had a redundant "mode"
attribute, which has always been "subsys". This finally
introduces a new mode "capabilities", which will be used
by the LXC driver for device assignment. Since container
based virtualization uses a single kernel, the idea of
assigning physical PCI devices doesn't make sense. It is
still reasonable to assign USB devices, but for assigning
arbitrary nodes in /dev, the new 'capabilities' mode is
to be used.

The first capability support is 'storage', which is for
assignment of block devices. Functionally this is really
pretty similar to the <disk> support. The only difference
is the device node name is identical in both host and
container namespaces.

    <hostdev mode='capabilities' type='storage'>
      <source>
        <block>/dev/sdf1</block>
      </source>
    </hostdev>

The second capability support is 'misc', which is for
assignment of character devices. There is no existing
parallel to this. Again the device node is the same
inside & outside the container.

    <hostdev mode='capabilities' type='misc'>
      <source>
        <char>/dev/input/event3</char>
      </source>
    </hostdev>

The reason for keeping the char & storage devices
separate in the domain XML, is to mirror the split
in the node device XML. NB the node device XML does
not yet report character devices, but that's another
new patch to come

09938bb3b0 conf: add optional attribte primary to video <model> element
If there are multiple video devices
primary = 'yes' marks this video device as the primary one.
The rest are secondary video devices. No more than one could be
mark as primary. If none of them has primary attribute, the first
one will be the primary by default like what it was.
The reason of this changing is that for qemu, only one primary video
device is permitted which can be of any type. For secondary video
devices, only qxl is allowd. Primary attribute removes the restriction
that the first have to be the primary one.

We always put the primary video device into the first position of
video device structure array after parsing.

2d5cd1d724 network: add support for DHCPv6
The DHCPv6 support includes IPV6 dhcp-range and dhcp-host for one
IPv6 subnetwork on one interface.  This support will only work
if dnsmasq version >= 2.64; otherwise an error occurs if
dhcp-range or dhcp-host is specified for an IPv6 address.

Essentially, this change provides the same DHCP support for IPv6
that has been available for IPv4.

With dnsmasq >= 2.64, support for the RA service is also now provided
by dnsmasq (radvd is no longer used/started). (Although at least one
version of dnsmasq prior to 2.64 "supported" IPv6 Router
Advertisement, there were bugs (fixed in 2.64) that rendered it
unusable.)

Documentation and the network schema has been updated
to reflect the new support.

Based on a patch originally authored by Daniel De Graaf

  http://lists.xen.org/archives/html/xen-devel/2012-05/msg00565.html

This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is
designated 'technology preview' only and is incompatible with Xen 4.2
libxl.  Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.

705e67d40b network: allow guest to guest IPv6 without gateway definition
This patch adds the capability for virtual guests to do IPv6
communication via a virtual network interface with no IPv6 (gateway)
addresses specified.  This capability has always been enabled by
default for IPv4, but disabled for IPv6 for security concerns, and
because it requires the ip6tables command to be operational (which
isn't the case on a system with the ipv6 module completely disabled).

This patch adds a new attribute "ipv6" at the toplevel of a <network>
object.  If ipv6='yes', the extra ip6tables rules required to permite
inter-guest communications are added when the network is started. If
it is 'no', or not present, those rules will not be added; thus the
default behavior doesn't change, so there should be no compatibility
issues with any existing installations.

Note that virtual guests cannot communication with the virtualization
host via this interface, because the following kernel tunable has
been set:

   net.ipv6.conf.<bridge_interface_name>.disable_ipv6 = 1

This assures that the bridge interface will not have an IPv6
link-local (fe80::) address.

To control this behavior so that it is not enabled by default, the parameter
ipv6='yes' on the <network> statement has been added.

Documentation related to this patch has been updated.
The network schema has also been updated.

a2d2b80fbd Add Gluster protocol as supported network disk backend
This patch introduces the RNG schema and updates necessary data strucutures
to allow various hypervisors to make use of Gluster protocol as one of the
supported network disk backend. Next patch will add support to make use of
this feature in Qemu since it now supports Gluster protocol as one of the
network based storage backend.

Two new optional attributes for <host> element are introduced - 'transport'
and 'socket'. Valid transport values are tcp, unix or rdma. If none specified,
tcp is assumed. If transport is unix, socket specifies path to unix socket.

This patch allows users to specify disks on gluster backends like this:

    <disk type='network' device='disk'>
      <driver name='qemu' type='raw'/>
      <source protocol='gluster' name='Volume1/image'>
        <host name='example.org' port='6000' transport='tcp'/>
      </source>
      <target dev='vda' bus='virtio'/>
    </disk>

    <disk type='network' device='disk'>
      <driver name='qemu' type='raw'/>
      <source protocol='gluster' name='Volume2/image'>
        <host transport='unix' socket='/path/to/sock'/>
      </source>
      <target dev='vdb' bus='virtio'/>

4201a7ea1c snapshot: new XML for external system checkpoint
Each <domainsnapshot> can now contain an optional <memory>
element that describes how the VM state was handled, similar
to disk snapshots.  The new element will always appear in
output; for back-compat, an input that lacks the element will
assume 'no' or 'internal' according to the domain state.

Along with this change, it is now possible to pass <disks> in
the XML for an offline snapshot; this also needs to be wired up
in a future patch, to make it possible to choose internal vs.
external on a per-disk basis for each disk in an offline domain.
At that point, using the --disk-only flag for an offline domain
will be able to work.

For some examples below, remember that qemu supports the
following snapshot actions:

qemu-img: offline external and internal disk
savevm: online internal VM and disk
migrate: online external VM
transaction: online external disk

=====
<domainsnapshot>
  <memory snapshot='no'/>
  ...
</domainsnapshot>

implies that there is no VM state saved (mandatory for
offline and disk-only snapshots, not possible otherwise);
using qemu-img for offline domains and transaction for online.

=====
<domainsnapshot>
  <memory snapshot='internal'/>
  ...
</domainsnapshot>

state is saved inside one of the disks (as in qemu's 'savevm'
system checkpoint implementation).  If needed in the future,
we can also add an attribute pointing out _which_ disk saved
the internal state; maybe disk='vda'.

=====
<domainsnapshot>
  <memory snapshot='external' file='/path/to/state'/>
  ...
</domainsnapshot>

This is not wired up yet, but future patches will allow this to
control a combination of 'virsh save /path/to/state' plus disk
snapshots from the same point in time.

=====

So for 1.0.1 (and later, as needed), I plan to implement this table
of combinations, with '*' designating new code and '+' designating
existing code reached through new combinations of xml and/or the
existing DISK_ONLY flag:

domain  memory  disk   disk-only | result
-----------------------------------------
offline omit    omit   any       | memory=no disk=int, via qemu-img
offline no      omit   any       |+memory=no disk=int, via qemu-img
offline omit/no no     any       | invalid combination (nothing to snapshot)
offline omit/no int    any       |+memory=no disk=int, via qemu-img
offline omit/no ext    any       |*memory=no disk=ext, via qemu-img
offline int/ext any    any       | invalid combination (no memory to save)
online  omit    omit   off       | memory=int disk=int, via savevm
online  omit    omit   on        | memory=no disk=default, via transaction
online  omit    no/ext off       | unsupported for now
online  omit    no     on        | invalid combination (nothing to snapshot)
online  omit    ext    on        | memory=no disk=ext, via transaction

a3e95abeb5 Document bracket whitespace rules & add syntax-check rule
This documents the following whitespace rules

      if(foo)   // Bad
      if (foo)  // Good

      int foo (int wizz)  // Bad
      int foo(int wizz)   // Good

      bar = foo (wizz);  // Bad
      bar = foo(wizz);   // Good

      typedef int (*foo) (int wizz);  // Bad
      typedef int (*foo)(int wizz);   // Good

      int foo( int wizz );  // Bad
      int foo(int wizz);    // Good

There is a syntax-check rule extension to validate all these rules.
Checking for 'function (...args...)' is quite difficult since it
needs to ignore valid usage with keywords like 'if (...test...)'
and while/for/switch. It must also ignore source comments and
quoted strings.

It is not possible todo this with a simple regex in the normal
syntax-check style. So a short Perl script is created instead
to analyse the source. In practice this works well enough. The
only thing it can't cope with is multi-line quoted strings of
the form

 "start of string\
more lines\
more line\
the end"

but this can and should be written as

 "start of string"
 "more lines"
 "more line"
 "the end"

with this simple change, the bracket checking script does not
have any false positives across libvirt source, provided it
is only run against .c files. It is not practical to run it
against .h files, since those use whitespace extensively to
get alignment (though this is somewhat inconsistent and could
arguably be fixed).

The only limitation is that it cannot detect a violation where
the first arg starts with a '*', eg

   foo(*wizz);

since this generates too many false positives on function
typedefs which can't be supressed efficiently.

On F17 at least, every time libvirtd starts we get this in syslog:

This comes from cyrus-sasl, and happens regardless of whether the
gssapi plugin is requested, which is what actually uses
/etc/libvirt/krb5.tab.

While cyrus-sasl shouldn't complain, we can easily make it shut up by
commenting out the keytab value by default.

Also update the keytab comment to the more modern one from qemu's

before libvirt has been taught to handle it.  However, to properly

f108944ae0 doc: Sort out the relationship between <vcpu>, <vcpupin>, and <emulatorpin>
These 3 elements conflicts with each other in either the doc
or the underlying codes.

Current problems:

Problem 1:

The doc shouldn't simply say "These settings are superseded
by CPU tuning. " for element <vcpu>. As except the tuning, <vcpu>
allows to specify the current, maxmum vcpu number. Apart from that,
<vcpu> also allows to specify the placement as "auto", which binds
the domain process to the advisory nodeset from numad.

Problem 2:

Doc for <vcpu> says its "cpuset" specify the physical CPUs
that the vcpus can be pinned. But it's not the truth, as
actually it only pin domain process to the specified physical
CPUs. So either it's a document bug, or code bug.

Problem 3:

Doc for <vcpupin> says it supersed "cpuset" of <vcpu>, it's
not quite correct, as each <vcpupin> specify the pinning policy
only for one vcpu. How about the ones which doesn't have
<vcpupin> specified? it says the vcpu will be pinned to all
available physical CPUs, but what's the meaning of attribute
"cpuset" of <vcpu> then?

Problem 4:

Doc for <emulatorpin> says it pin the emulator threads (domain
process in other context, perhaps another follow up patch to
cleanup the inconsistency is needed) to the physical CPUs
specified its attribute "cpuset". Which conflicts with
<vcpu>'s "cpuset". And actually in the underlying codes,
it set the affinity for domain process twice if both
"cpuset" for <vcpu> and <emulatorpin> are specified,
and <emulatorpin>'s pinning will override <vcpu>'s.

Problem 5:

When "placement" of <vcpu> is "auto" (I.e. uses numad to
get the advisory nodeset to which the domain process is
pinned to), it will also be overridden by <emulatorpin>,

This patch is trying to sort out the conflicts or bugs by:

1) Don't say <vcpu> is superseded by <cputune>

2) Keep the semanteme for "cpuset" of <vcpu> (I.e. Still says it
   specify the physical CPUs the virtual CPUs). But modifying it
   to mention it also set the pinning policy for domain process,
   and the CPU placement of domain process specified by "cpuset"
   of <vcpu> will be ingored if <emulatorpin> specified, and
   similary, the CPU placement of vcpu thread will be ignored
   if it has <vcpupin> specified, for vcpu which doesn't have
   <vcpupin> specified, it inherits "cpuset" of <vcpu>.

3) Don't say <vcpu> is supersed by <vcpupin>. If neither <vcpupin>
   nor "cpuset" of <vcpu> is specified, the vcpu will be pinned
   to all available pCPUs.

4) If neither <emulatorpin> nor "cpuset" of <vcpu> is specified,
   the domain process (emulator threads in the context) will be
   pinned to all available pCPUs.

5) If "placement" of <vcpu> is "auto", <emulatorpin> is not allowed.

6) hotplugged vcpus will also inherit "cpuset" of <vcpu>

Codes changes according to above document changes:

1) Inherit def->cpumask for each vcpu which doesn't have <vcpupin>
   specified, during parsing.

2) ping the vcpu which doesn't have <vcpupin> specified to def->cpumask
   either by cgroup for sched_setaffinity(2), which is actually done
   by 1).

3) Error out if "placement" == "auto", and <emulatorpin> is specified.
   Otherwise, <emulatorpin> is honored, and "cpuset" of <cpuset> is
   ignored.

4) Setup cgroup for each hotplugged vcpu, and setup the pinning policy
   by either cgroup or sched_setaffinity(2).

5) Remove cgroup and <vcpupin> for each hot unplugged vcpu.

Patches are following (6 in total except this patch)

893647671b locking: Implement lock failure action in sanlock driver
While the changes to sanlock driver should be stable, the actual
implementation of sanlock_helper is supposed to be replaced in the
future. However, before we can implement a better sanlock_helper, we
need an administrative interface to libvirtd so that the helper can just
pass a "leases lost" event to the particular libvirt driver and
everything else will be taken care of internally. This approach will
also allow libvirt to pass such event to applications and use
appropriate reasons when changing domain states.

The temporary implementation handles all actions directly by calling
appropriate libvirt APIs (which among other things means that it needs
to know the credentials required to connect to libvirtd).
