[lxc-users] Convert virtual machine to LXC container

[Fajar A. Nugraha]

Sorry, my mistake. I meant "lxc-console". And I just rechecked, apparently
there's the equivalent "lxc console" command as well.

Ignore my comment about "lxc-attach" earlier. You should be able to use lxd
rootfs for lxc as long as:
- you have the correct uid mapping (it's simpler if you just use privileged
container. Otherwise just setup uid map on lxc config file manually)
- you have a suitable lxc config file (the easiest way is probably to
create a new lxc container, then replace the original rootfs with the one
from rsync/lxd-p2c)
