Standardizing an MSR or other hypercall to get an RNG seed?
...standardizing MSR
to get RND and detection mechanism for this MSR. RND MSR is in no way
unique here. There are other mechanisms that are virtually identical
between hypervisors but have different gust/hypervisor interfaces and
are detected differently on different hypervisors. Examples are pvclock,
pveoi may be others.

I'm not sure what you mean by "this mechanism?" Are you suggesting that each hypervisor put "CrossHVPara\0" somewhere in the 0x40000000 - 0x400fffff CPUID range, and an OS has to do a full scan of this CPUID range on boot to find it? That seems pretty inefficient. An OS will take 1000's of hypervisor intercepts on every boot just to search this CPUID range.
