Can add weight to these findings. Tested with Xen 4.12.1 and the cpuid
line suggested and it looks like my Windows VM has come up with 4 vCPUS.
I can't RDP in to make sure its 100% booted, but it certainly isn't
doing the crash dump cycle - and CPU usage is consistent with being
successfully booted.
