To correct myself, there is "phenom" in the 'cpu_map.xml', although this is not the second generation.
However the question is whether it is at all important to libvirt/qemu given the limited number of used properties.

Also, this can be surpassed by cpu mode='host-passthrough' although even that is not fully applied, probably related to the limitation of the qemu BIOS i.e. due to the lack of susceptibility to "subtle" differences in socket - core relation.

But even that did not help.

Finally, one small thing helped, and this is not the daisy.
