[libvirt] [PATCH v2 02/45] domcaps: Add support for listing supported CPU models
Jiri Denemark
jdenemar at redhat.com
Mon Sep 19 13:30:11 UTC 2016
The patch adds <cpu> element to domain capabilities XML:
<cpu>
<mode name='host-passthrough' supported='yes'/>
<mode name='host-model' supported='yes'/>
<mode name='custom' supported='yes'>
<model>Broadwell</model>
<model>Broadwell-noTSX</model>
...
</mode>
</cpu>
Applications can use it to inspect what CPU configuration modes are
supported for a specific combination of domain type, emulator binary,
guest architecture and machine type.

Notes:
Version 2:
- switched to VIR_STEAL_PTR
- s/alloc/nmodels_max/ and s/count/nmodels/
- added cross reference to formatdomain.html#elementsCPU
