Hi,
If it does, then the host kernel should be 4.4 or later. (If we want to capture version numbers, then for each minor release, the latest patch level should be required: 4.4.16, 4.5.7, 4.6.5, 4.7.0, because there have been a number of KVM tweaks and stable backports for SMM support.)
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. Laszlo
