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>
