[A small addendum to what Martin says.]

Jon, you can use `virt-host-validate` to check the above, if everything
is setup correctly, it should look like that:

  $ sudo virt-host-validate
    QEMU: Checking for hardware virtualization                                 :
PASS
    QEMU: Checking for device /dev/kvm                                         :
PASS
    QEMU: Checking for device /dev/vhost-net                                   :
PASS
    QEMU: Checking for device /dev/net/tun                                     :
PASS
     LXC: Checking for Linux >= 2.6.26
: PASS
