KVM: nSVM: check for EFER.SVME=1 before entering guest EFER is set for L2 using svm_set_efer, which hardcodes EFER_SVME to 1 and hides an incorrect value for EFER.SVME in the L1 VMCB. Perform the check manually to detect invalid guest state. Reported-by: Krish Sadhukhan <krish.sadhukhan@oracle.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
