In order to solve this problem, the following libvirt commits are
required. They were also accepted in vivid, as described by bug #1396070
commit 3bc6dda6c55ed2ebc8604b9dc0410639eaede8cb

qemu_command: Split qemuBuildCpuArgStr
Move the CPU mode/model handling to its own function. This is just
code movement and re-indentation.

qemu: Don't compare CPU against host for TCG
Right now when building the qemu command line, we try to do various
unconditional validations of the guest CPU against the host CPU. However
this checks are overly applied. The only time we should use the checks
are:

Cpu: Add support for Power LE Architecture.
This adds support for PowerPC Little Endian architecture.,
and allows libvirt to spawn VMs based on 'ppc64le' architecture.

PowerPC : Add support for launching VM in 'compat' mode.
PowerISA allows processors to run VMs in binary compatibility ("compat")
mode supporting an older version of ISA. QEMU has recently added support to
explicitly denote a VM running in compatibility mode through commit 6d9412ea
& 8dfa3a5e85. Now, a "compat" mode VM can be run by invoking this qemu
commandline on a POWER8 host: -cpu host,compat=power7.

PowerPC:Improve PVR handling to fall back to cpu generation.
IBM Power processors differ uniquely across generations (such as power6,
power7, power8). Each generation signifies a new PowerISA version
that exhibits features unique to that generation.
The higher 16 bits of PVR for IBM Power processors encode the CPU
generation, while the CPU chip (sub)version is encoded in lower 16 bits.
commit 9265fd19b68d787e478f5e490524da794965a5f1

docs: Add documentation for compat mode.
Add documentation to explain how compat-mode can be invoked with libvirt
running on PowerPC architecture.
It also mentions that this change is available libvirt 1.2.11 onwards.

Test: Add a testcase for PowerPC compat mode cpu specification.
This introduces a testcase for PowerPC compat mode cpu
specification.

These patches have been tested -- they build fine against the libvirt 1.2.8
sources that are packaged with Ubuntu 14.10.
I have included a reference to the upstream commit in each case.
