VFSGuestFS requires the libguestfs python module & corresponding native
package to be present, and only works with KVM/QEMU enabled hosts.
VFSLocalFS requires loopback module, nbd module, qemu-nbd, kpartx and
a few other misc host tools
Neither of these should cause a VM getting stuck in the spawning
state, even if stuff they need is missing.
