libvirt: unknown OS type hvm

It took me a little while to narrow this down. Building a kvm guest with vmbuilder via libvirt I was getting the error “unknown OS type hvm”. When I compared the output of ‘virsh capabilities’ on a good host and the one that wasn’t working, the later was missing the kvm hvm entries. When I checked out the init script for kvm, I realized the the kernel module wasn’t loaded and a quick check of dmesg confirmed that virtualization was disabled in the bios.
