[libvirt] [PATCH] virt-host-validate: require fuse for LXC if compiled in

[Cedric Bosdonnat]

>>> Guido Günther <agx at sigxcpu.org> 10/12/17 6:12 PM >>>
Domains fail to start without fuse like

  error: internal error: guest failed to start: fuse: device not found, try 'modprobe fuse' first
  Failure in libvirt_lxc startup: no error

so check for it too.
