libvirt users - Aug 2012 - CPU Flags libvirt 0.9.12

Hi,

I?m using libvirt version 0.9.12 under Debian Squeeze with and AMD 
Opteron 4280. Executing the virsh capabilities command only show me the 
following flags:

<cpu>
<arch>x86_64</arch>
<model>Opteron_G4</model>
<vendor>AMD</vendor>
<topology sockets='1' cores='8' threads='2'/>
<feature name='nodeid_msr'/>
<feature name='wdt'/>
<feature name='skinit'/>
<feature name='ibs'/>
<feature name='osvw'/>
<feature name='cr8legacy'/>
<feature name='extapic'/>
<feature name='cmp_legacy'/>
<feature name='fxsr_opt'/>
<feature name='mmxext'/>
<feature name='osxsave'/>
<feature name='monitor'/>
<feature name='ht'/>
<feature name='vme'/>
</cpu>

Should not there be more flags supported by the CPU, for example the 
SVM-Flag for virtualization because executing cat /proc/cpuinfo gives me 
quite a lot of more flags and also the SVM Flag.

Cheers,
Mike

The output is correct as libvirt tries to find a "parent" processor
and
the flags that are in your output are just flags that your processor 
supports and the parent, in this case Opteron G4, doesn't.
