It is legal to set CPUID multiple times, so I think we need
if (static_cpu_has(X86_FEATURE_PCOMMIT) && nested) {
if (guest_cpuid_has_pcommit(vcpu))
vmx->nested.nested_vmx_secondary_ctls_high |=
SECONDARY_EXEC_PCOMMIT;
else
vmx->nested.nested_vmx_secondary_ctls_high &=
~SECONDARY_EXEC_PCOMMIT;
}
The INVPCID exit probably should be handled the same way as PCOMMIT;
moving both to a new nested_vmx_update_ctls_msrs probably makes sense.
This can be done on top of this series.
