[libvirt] [PATCH 0/9] New public API for computing baseline CPU

[Jiri Denemark]

Hi,

This series introduces a new virConnectBaselineCPU() API call for
computing baseline CPU model from a set of host CPU definitions.
The call accepts a list of <cpu>...</cpu> xml definitions taken from
host capabilities and returns an xml description of a guest CPU which is
supported by all hosts.

virsh is little bit less picky and accepts a file containing host CPU
definitions. It doesn't care what is outside of the <cpu/> tag, which
allows for concatenating outputs of virsh capabilities from several
hosts and feeding the result to virsh cpu-baseline.

This series can also be found on cpu-baseline branch of
git://gitorious.org/~jirka/libvirt/jirka-staging.git

In practice it works like this:

# virsh cpu-baseline /dev/stdin >guest-cpu <<EOF
<capabilities>
  <host>
    <cpu>
      <arch>x86_64</arch>
      <model>core2duo</model>
      <topology sockets='1' cores='2' threads='1'/>
      <feature name='lahf_lm'/>
      <feature name='xtpr'/>
      <feature name='cx16'/>
      <feature name='tm2'/>
      <feature name='est'/>
      <feature name='vmx'/>
    </cpu>
  </host>
</capabilities>
    <cpu>
      <arch>i686</arch>
      <model>pentiumpro</model>
      <topology sockets='1' cores='2' threads='1'/>
      <feature name='vme'/>
      <feature name='pse36'/>
      <feature name='pni'/>
      <feature name='monitor'/>
      <feature name='ssse3'/>
    </cpu>
    <cpu>
      <arch>x86_64</arch>
      <model>phenom</model>
    </cpu>
EOF

# cat guest-cpu
<cpu match='exact'>
  <model>qemu32</model>
  <feature policy='require' name='monitor'/>
  <feature policy='require' name='pse36'/>
</cpu>
