Better check /dev/kvm for the KVM_CAP_X86_SMM capability, otherwise the
rhel-7 kernel is out even though smm is backported.
Probably libvirt already has checks for other caps so it should be easy.
The problem is that KVM_CAP_X86_SMM does not guarantee that all the
tricky bugfixes are present in the host kernel.
