Earlier, when the number of vcpus was greater than the topology allowed,
libvirt didn't raise an error and continued, resulting in running qemu
with parameters making no sense. Even though qemu did not report any
error itself, the number of vcpus was set to maximum allowed by the
topology.
QEMU does not support security_model for anything but 'path' fs driver type.
Currently in libvirt, when security_model ( accessmode attribute) is not
specified it auto-generates it irrespective of the fs driver type, which
can result in a qemu error for drivers other than path. This patch ensures
that the qemu cmdline is correctly generated by taking into account the
fs driver type.

To add support for running libvirt on PowerPC, a CPU driver for the
PowerPC platform must be added.
Most generic cpu driver routines such as CPU compare, decode, etc
are based on CPUID comparison and are not relevant for non-x86
platforms.
Here, we introduce stubs for relevant PowerPC routines invoked by libvirt.

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

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 adds XML definitions for guest NUMA specification and contains
routines to parse the same. The guest NUMA specification looks like this:
<cpu>
...
<topology sockets='2' cores='4' threads='2'/>
<numa>
<cell cpus='0-7' memory='512000'/>
<cell cpus='8-15' memory='512000'/>
</numa>
...
</cpu>

This refactors the TAP creation code out of brAddTap into a new
function brCreateTap to allow it to be used on its own. I have also
changed ifSetInterfaceMac to brSetInterfaceMac and exported it since
it is will be needed by code outside of util/bridge.c in the next
patch.

Drivers load running persistent and transient domain configs before
inactive persistent domain configs, however only the latter would set a
domain's autostart flag. This mismatch between the loaded and on-disk
state could later cause problems with "virsh autostart":
# virsh autostart example
error: Failed to mark domain example as autostarted
error: Failed to create symlink '/etc/libvirt/qemu/autostart/example.xml to '/etc/libvirt/qemu/example.xml': File exists
This patch ensures the autostart flag is set correctly even when the
domain is already defined.
