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.
