It looks like the cause is that AMD has removed TBM instructions
compared to e.g. Piledriver, so libvirt resorts to a much older base
model (thanks to Dave Gilbert for sorting through the list of feature bits).

Can you please run this script:

http://libvirt.org/git/?p=libvirt.git;a=blob_plain;f=tests/cputestdata/cpu-gather.sh;h=83963557ec4075d351be09e17994ac5300bc5d1f;hb=HEAD

and send the output?

Thanks,

Paolo
