Hi,
I faced a similar problem when upgrading libvirt/qemu packages from
wheezy to wheezy-backports. Try to delete
/var/cache/libvirt/qemu/capabilities and restart libvirt-bin.

Same problem after changing from wheezy to jessie.

Preferred CPU model Opteron_G3 not allowed by hypervisor; closest
supported model will be used
has it anything to do with wrong detected cpu flags? I am using AMD
Kabini cpu and Opteron G3 map is used both under wheezy and jessie.

What it has to do with kernel version?
