Just for completeness' sake: the most supportable and portable way to
check for that is to use libvirt's virConnectGetCapabilities[1] (or
'virsh capabilities')

Programs that need to know whether kvm is enabled, shouldn't go poking
around /sys etc. - look at the capabilities XML instead. And if there's
info missing that you need, ask on libvir-list and it'll happen somehow.
