Hi Jan and maillist,
Does nest VMX support vmexit MSR store/load and vmenter MSR load now?
I tried to set "VM-exit MSR-store address" with valid address and set
"VM-exit MSR-store count" to 1, then the vmenter fails. Anything else
should I set to use these features?

This is not supported (but mandatory VMX features).
