Commit id 'a4e86390' modified the command line to allow --ipadd multiple
times, which caused Coverity to notice a latent memory leak with the
'ipAddr' string not being VIR_FREE()'d

The default value should be 16 MiB instead of 8 MiB. Only really old
version of upstream QEMU used the 8 MiB as default for vga framebuffer.
Without this change if you update your libvirt where we introduced the
"vgamem" attribute for QXL video device the value will be set to 8 MiB,
but previously your guest had 16 MiB because we didn't pass any value to
QEMU command line which means QEMU used its own 16 MiB as default.
This will affect all users with guest's display resolution higher than
1920x1080.

It was brought to my attention that some -boot options may not
work with UEFI. For instance, rebootTimeout is very SeaBIOS
specific,splash logo is not implemented yet on OVMF, and so on.
We should document this limitation at least.

Commit 6b9964 enforces checking invalid use of VSH_OT_STRING with

VSH_OT_DATA without VSH_OFLAG_REQ and also fix existing misuse.

The way that we currently generate the <driver/> for <controller/> is
just madness:
<controller type='scsi' index='0' model='virtio-scsi'>
<driver queues='12'/>
<driver cmd_per_lun='123'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</controller>
It's obvious that we should be aiming at the following:
<controller type='scsi' index='0' model='virtio-scsi'>
<driver queues='12' cmd_per_lun='123'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</controller>

Remove the resize flag and use the same code path for all callers.
This flag was added by commit 18f0316 to allow virStorageFileResize
use 'safezero' while preserving the behavior.
Explicitly return -2 when a fallback to a different method should
be done, to make the code path more obvious.
Fail immediately when ftruncate fails in the mmap method,
as we did before commit 18f0316.
The 'pool-build' command description for --overwrite and --no-overwrite
indicated usage for only 'filesystem' pools; however, the 'disk' pool
also supports the flags as of commit id 'afa1029a'. So add a description
for that usage.

Well, the parallel build doesn't work as there are not dependencies
set correctly. When running 'make -j' I see this error:
make[2]: Entering directory '/home/zippy/work/libvirt/libvirt.git/src'
GEN util/virkeymaps.h
GEN locking/lock_protocol.h
make[2]: *** No rule to make target 'xenconfig/xen_xl_disk.h', needed by 'all'. Stop.
make[2]: *** Waiting for unfinished jobs....
GEN lxc/lxc_controller_dispatch.h
The fix is to correctly set dependencies by letting make know that .c
and .h are to be generated from .l. Moreover, the section is moved
closer to the other section which uses it.

VMware ESX does not always set the "serialX.fileType" tag in VMX files. The
default value for this tag is "device", and when adding a new serial port
of this type VMware will omit the fileType tag. This caused libvirt to
fail to parse the VMX file. Fixed by making this tag optional and using
"device" as a default value. Also updated vmx2xmltest to test for this
case.

Ever since commit 2c78051 split out a helper library for the sake of
changing CFLAGS, a VPATH build with xenconfig enabled has failed:
CC xenconfig/libvirt_xenxldiskparser_la-xen_xl_disk.lo
../../src/xenconfig/xen_xl_disk.l:37:21: fatal error: xen_xl.h: No such file or directory
# include "xen_xl.h"
^
compilation terminated.
Makefile:9462: recipe for target 'xenconfig/libvirt_xenxldiskparser_la-xen_xl_disk.lo' failed
The solution is to tell the build to look for xen_xl.h relative
to $(srcdir), since we keep that file under version control.
[Not fixed here - the raw use of -Wno-unused-parameter in CFLAGS
is NOT portable; ideally, we should be doing a configure test
and only supplying that argument when we know the compiler supports
-Wunused-parameter; but that's a patch for another day]
[Not fixed here - there are still issues with parallel builds hitting
a race between generating the files and trying to compile/distribute
them]
* src/Makefile.am (libvirt_xenxldiskparser_la_CFLAGS): Add another
include directory.

In one of my previous commits (311b4a67) I've tried to allow to
pass regular system pages to <hugepages>. However, there was a
little bug that wasn't caught. If domain has guest NUMA topology
defined, qemuBuildNumaArgStr() function takes care of generating
corresponding command line. The hugepages backing for guest NUMA
nodes is handled there too. And here comes the bug: the hugepages
setting from XML is stored in KiB internally, however, the system
pages size was queried and stored in Bytes. So the check whether
these two are equal was failing even if it shouldn't.

Make use of the ebtables functionality to be able to filter certain
parameters of icmpv6 packets. Extend the XML parser for icmpv6 types,
type ranges, codes, and code ranges. Extend the nwfilter documentation,
schema, and test cases.
Being able to filter icmpv6 types and codes helps extending the DHCP
snooper for IPv6 and filtering at least some parameters of IPv6's NDP
(Neighbor Discovery Protocol) packets. However, the filtering will not
be as good as the filtering of ARP packets since we cannot
check on IP addresses in the payload of the NDP packets.

In commit 540c339a25 the whole domain
reference counting was refactored in the qemu driver. Domain jobs now
don't need to reference the domain object as they now expect the
reference from the calling function.
However, the patch forgot to remove the unref call in case we exit the
monitor when we were acquiring a nested job. This caused the daemon to
crash on a subsequent access to the domain object once we've done an
operation requiring a nested job for a monitor access.
An easy reproducer case:
1) Start a vm with qcow disks
2) virsh snapshot-create-as DOMNAME
3) virsh dumpxml DOMNAME
4) daemon crashes in a semi-random spot while accessing a now-removed VM
object.
Fortunately, the commit wasn't released yet, so there are no security
implications.

When migrate a vm, we will generate a xml via qemuDomainDefFormatLive and
pass this xml to target libvirtd. Libvirt will use the current network
state in def->data.network.actual to generate the xml, this will make
migrate failed when we set a network type guest interface use a macvtap
network as a source in a vm then migrate vm to another host(which has the
different macvtap network settings: different interface name, bridge name...)
Add a flag check in virDomainNetDefFormat, if we set a VIR_DOMAIN_XML_MIGRATABLE
flag when call virDomainNetDefFormat, we won't get the current vm interface
state.

When setting new bandwidth limits via
virDomainSetInterfaceParameters, the old ones are cleared first.
However, if setting the new ones fails, the old are already gone
and interface is left in inconsistent state. Therefore, right
before failing we ought to try to restore the old bandwidth.

Lack of a lease (whether mac is given or not) is a normal expected

okay as 0 if there is no lease). There is no need to raise an error.

warning message like this:
Qemu reported unknown VM status: 'guest-panicked'

Vzctl man page says that --ipadd can be provided multiple times to add
several IP addresses. Looping over the configured ip addresses to add
one --ipadd for each. This would even handle the multiple IPs handled
by openvz_conf.c
Add the possibility to have more than one IP address configured for a
domain network interface. IP addresses can also have a prefix to define
the corresponding netmask.
Add a default implementation of virNetDevSetIPv4Address using netlink
and libnl. This avoids requiring /usr/sbin/ip or /usr/sbin/ifconfig
external binaries.
The typical case for the problem is starting a domain needing a network
that isn't started. Even after starting the network, we get an unknown error
when starting the container.
This is due to dynamic security label not being removed.
