I've read again the wiki page and as you might ask for it here's the cpuinfo
flags output:
fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush
dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm
constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc
aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3
cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic popcnt tsc_deadline_timer aes
xsave avx lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi
flexpriority ept vpid
If we check the mentioned cpu_max.xml file we find :
<model name='SandyBridge'>
<model name='Westmere'/>
<feature name='pclmuldq'/>
<feature name='x2apic'/>
<feature name='tsc-deadline'/>
<feature name='xsave'/>
<feature name='avx'/>
<feature name='rdtscp'/>
</model>
So I suppose that pclmuldq is expected in the flags but it's not there. Isn't
it?
So I need to add my specific model at hand and trying to infer which are the
specific flags for it?
Or maybe that needs something more to be hacked in the libvirt code... and thus
I should wait for libvirt people to add it? Well, I mean, going to their ML and
asking there?
Or isn't there any hope for my particular sandbridge cpu?
Thank you.
