[libvirt] [PATCH v2 3/3] cpu: Add cpu test cases for PPC CPU driver.

[Shivaprasad G Bhat]

Verified-by: Shivaprasad
The cpu model to pvr value mappings are
    POWER7 -> '0x003f0200'
    POWER7_v2.1 -> '0x003f0201'
    POWER7_v2.3 -> '0x003f0203'
    POWER7+_v2.1 -> '0x004a0201'
    POWER8_v1.0 -> '0x004b0100'

Verified on,
libvirt version: 1.1.2
Host : Fedora 19 - 3.11.0-rc7+
Guest : Fedora 19 - 3.9.2-301.fc19.ppc64p7
qemu - version 1.6.0

Test Results :

 On Host :
[root at ltcfbl9cb libvirt]# cat ../usr/etc/libvirt/qemu/shiv.xml | grep -e
cpu  -e model
  <vcpu placement='static'>16</vcpu>
  <cpu mode='custom' match='exact'>
    <model fallback='allow'>POWER7_v2.1</model>
  </cpu>

> Currently, PPC CPU driver doesn't support to parse guest data.
> It can't pass CPU parameters to Qemu command line.
>
> This patchset is to implement .guestData to support to parse guest
> CPU configuration and .update to support host-model and
host-passthrough.
>
> The guest CPU configuration is as the following:
>    <cpu match='exact'>
>      <model>POWER7_v2.3</model>
>      <vendor>IBM</vendor>
>    </cpu>
>
> v2 -> v1:
>    * Remove features functions calling for non-x86 platform (Doug
Goldstein)
>    * Improve update code.
>    * Merge update code with guestData.
>
> Li Zhang (3):
>    Remove CPU features check for non-x86 platform.
>    cpu: Implement guestData and update for PPC
>    cpu: Add cpu test cases for PPC CPU driver.
