To add to this, I've tried using the boot options to set the cpu mask
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.
