KVM: vmx: use MSR_IA32_TSX_CTRL to hard-disable TSX on guest that lack it If X86_FEATURE_RTM is disabled, the guest should not be able to access MSR_IA32_TSX_CTRL. We can therefore use it in KVM to force all transactions from the guest to abort. Tested-by: Jim Mattson <jmattson@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
