Improve the documentation of what forms a valid <address> element,
since these elements appear in numerous devices.
* docs/formatdomain.html.in (elementsAddress): New section.
(elementsControllers, elementsUSB, elementsNICS, elementsInput)
(elementsHub, elementsCharChannel, elementsSound): Refer to it.
In QEMU PPC64 we have a network device called "spapr-vlan". We can specify
this using the existing syntax for network devices, however libvirt
currently rejects "spapr-vlan" in virDomainNetDefParseXML() because of
the "-". Fix the code to accept "-".
* src/conf/domain_conf.c (virDomainNetDefParseXML): Allow '-' in
model name, and be more efficient.
* docs/schemas/domaincommon.rng: Limit valid model names to match code.
Based on a patch by Michael Ellerman.
ppc64 as new arch type and pseries as new machine type are
added under <os> ... </os>.

This patch is to expose the fabric_name of fc_host class, which
might be useful for users who wants to known which fabric the
(v)HBA connects to.
The patch also adds the missed capabilities' XML schema of scsi_host,
(of course, with fabric_wwn added), and update the documents
(docs/formatnode.html.in)

If we ensure that virNodeSuspendGetTargetMask always resets
*bitmask to zero upon failure, there is no need for the
powerMgmt_valid field.
* src/util/virnodesuspend.c: Ensure *bitmask is zero upon
failure
* src/conf/capabilities.c, src/conf/capabilities.h: Remove
powerMgmt_valid field
* src/qemu/qemu_capabilities.c: Remove powerMgmt_valid
The capabilities XML uses the x86 specific terms 'S3', 'S4'
and 'Hybrid-Syspend'. Switch it to use the same terminology
as the API constants and virsh options, eg 'suspend_mem'
'suspend_disk' and 'suspend_hybrid'
* docs/formatcaps.html.in, docs/schemas/capability.rng,
src/conf/capabilities.c: Rename suspend constants
This adds per-device weights to <blkiotune>. Note that the
cgroups implementation only supports weights per block device,
and not per-file within the device; hence this option must be
global to the domain definition rather than tied to individual
<devices>/<disk> entries:
<domain ...>
<blkiotune>
<device>
<path>/path/to/block</path>
<weight>1000</weight>
</device>
</blkiotune>
..
This patch also adds a parameter --device-weights to virsh command
blkiotune for setting/getting blkiotune.weight_device for any
hypervisor that supports it. All <device> entries under
<blkiotune> are concatenated into a single string attribute under
virDomain{Get,Set}BlkioParameters, named "device_weight".

Some systems support a feature known as 'Hybrid-Suspend', apart from the
usual system-wide sleep states such as Suspend-to-RAM (S3) or Suspend-to-Disk
(S4). Add the functionality to discover this power management feature and
export it in the capabilities XML under the <power_management> tag.
virt-xml-validate fails when run on a domain XML file of type 'vbox'.
For failing test case, see https://bugzilla.redhat.com/show_bug.cgi?id=757097
This patch updates the XML schema to accept all valid hypervisor
types, as well as dropping hypervisor types that are not in use
by the current code base.

This patch exports KVM Host Power Management capabilities as XML so that
higher-level systems management software can make use of these features
available in the host.
The script "pm-is-supported" (from pm-utils package) is run to discover if
Suspend-to-RAM (S3) or Suspend-to-Disk (S4) is supported by the host.
If either of them are supported, then a new tag "<power_management>" is
introduced in the XML under the <host> tag.
However in case the query to check for power management features succeeded,
but the host does not support any such feature, then the XML will contain
an empty <power_management/> tag. In the event that the PM query itself
failed, the XML will not contain any "power_management" tag.
To use this, new APIs could be implemented in libvirt to exploit power
management features such as S3/S4.

This patch modifies the NWFilter parameter parser to support multiple
elements with the same name and to internally build a list of items.
An example of the XML looks like this:
<parameter name='TEST' value='10.1.2.3'/>
<parameter name='TEST' value='10.2.3.4'/>
<parameter name='TEST' value='10.1.1.1'/>
The list of values is then stored in the newly introduced data type
virNWFilterVarValue.
The XML formatter is also adapted to print out all items in alphabetical
order sorted by 'name'.
This patch also fixes a bug in the XML schema on the way.

This patch adds several aspects of documentation about the network filtering
system:
- chains, chains' priorities and chains' default priorities
- talks about lists of elements, i.e., a variable assigned multiple values
(part of already ACK-ed series)
- already mentions the vlan, stp and mac chains added later on
(https://www.redhat.com/archives/libvir-list/2011-October/msg01238.html)
- mentions limitations of vlan filtering (when sent by VM) on Linux systems
This patch enables chains that have a known prefix in their name.
Known prefixes are: 'ipv4', 'ipv6', 'arp', 'rarp'. All prefixes
are also protocols that can be evaluated on the ebtables level.
Following the prefix they will be automatically connected to an interface's
'root' chain and jumped into following the protocol they evaluate, i.e.,
a table 'arp-xyz' will be accessed from the root table using
ebtables -t nat -A <iface root table> -p arp -j I-<ifname>-arp-xyz
thus generating a 'root' chain like this one here:
Bridge chain: libvirt-O-vnet0, entries: 5, policy: ACCEPT
-p IPv4 -j O-vnet0-ipv4
-p ARP -j O-vnet0-arp
-p 0x8035 -j O-vnet0-rarp
-p ARP -j O-vnet0-arp-xyz
-j DROP
where the chain 'arp-xyz' is accessed for filtering of ARP packets.

This patch extends the filter XML to support priorities of chains
in the XML. An example would be:
<filter name='allow-arpxyz' chain='arp-xyz' priority='200'>
[...]
</filter>
The permitted values for priorities are [-1000, 1000].
By setting the priority of a chain the order in which it is accessed
from the interface root chain can be influenced.

Allow the datacenter and compute resource parts of the path
to be prefixed with folders. Therefore, the way the path is
parsed has changed. Before, it was split in 2 or 3 items and
the items' meanings were determined by their positions. Now
the path can have 2 or more items and the the vCenter server
is asked whether a folder, datacenter of compute resource
with the specified name exists at the current hierarchy level.
Before the datacenter and compute resource lookup automatically
traversed folders during lookup. This is logic got removed
and folders have to be specified explicitly.
The proper datacenter path including folders is now used when
accessing a datastore over HTTPS. This makes virsh dumpxml
and define work for datacenters in folders.

However, this patch introduces only XML part of this new

In a recent expansion of the documentation on network forward modes, I
incorrectly stated that incoming sessions to guests on routed networks
were blocked. This is true for guests on NATed networks, but not
routed. This patch corrects that error, and adds a pointer to the
nwfilter page for those who do want to restrict incoming sessions to
hosts on routed networks.
Clarify some of the effects of managed passthrough <hostdev> devices;
with recent changes (commit d093547), a nodedev-reattach is only needed
to pair up to an explicit nodedev-dettach (but beware that older

hood when using the gui to hotplug a hostdev device).
* docs/formatdomain.html.in: Mention reattach.
* tools/virsh.pod (nodedev): Mention managed mode.
This adds support for a libvirt client configuration file
either /etc/libvirt/libvirt.conf for privileged clients,

Any call to virConnectOpen with a non-NULL URI will first
attempt to match against the uri_aliases list. An application
can disable this by using VIR_CONNECT_NO_ALIASES
* docs/uri.html.in: Document URI aliases
* include/libvirt/libvirt.h.in: Add VIR_CONNECT_NO_ALIASES

A few people have attempted to use the new forwarding modes with older
versions of libvirt. The docs where the modes are described have
always stated the minimum required libvirt version, but the examples
at the end didn't, which I believe is what has caused the confusion.
Similarly, the section on portgroups now has a version tag added at
the beginning.
I also noticed that there was no example of defining a <dns> hostname,
so I added one, as well as making the domain name example more
recognizable (by adding ".com" to the domain).
VirtFS allows the user to choose between path/handle based fs driver.
As of now, libvirt hardcoded path based driver only. This patch provides
a solution to allow user to choose between path/handle based fs driver.

<driver type='handle'/>
<source dir='/folder/to/share1'/>
<target dir='mount_tag1'/>
</filesystem>
<filesystem type='mount'>
