kvm: vmx: Raise #UD on unsupported XSAVES/XRSTORS A guest may not be configured to support XSAVES/XRSTORS, even when the host does. If the guest does not support XSAVES/XRSTORS, clear the secondary execution control so that the processor will raise #UD. Also clear the "allowed-1" bit for XSAVES/XRSTORS exiting in the IA32_VMX_PROCBASED_CTLS2 MSR, and pass through VMCS12's control in the VMCS02. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
