Hi,
I guess this is the wrong approach:
Libvirt does manage cpu type in an xml file, you would have to alter this xml file:
/usr/share/libvirt/cpu_map.xml
HTH
PS: Maybe add an feature request upstream to enable this for all libvirt users?
I have seen this request quite some time on different mailing lists.

Has anyone here managed to get cpu masking working via libvirt? Intention to enable VM migrations between hosts of a different CPU generation.
To add to this, I've tried using the boot options to set the cpu mask instead:
xen_commandline : dom0_mem=2048M,max:2048M loglvl=all guest_loglvl=all cpuid_mask_ecx=0x009ee3fd cpuid_mask_edx=0xbfebfbff
Unfortunately still no luck. There's no errors in xm dmesg to indicate the settings were / weren't applied, it simply doesn't seem to do anything.
