KVM: VMX: enable VMXON check with SMX enabled (Intel TXT)
Per document, for feature control MSR: Bit 1 enables VMXON in SMX operation. If the bit is clear, execution of VMXON in SMX operation causes a general-protection exception. Bit 2 enables VMXON outside SMX operation. If the bit is clear, execution of VMXON outside SMX operation causes a general-protection exception. This patch is to enable this kind of check with SMX for VMXON in KVM. Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
