Re: [libvirt] [PATCH RFC 4/5] lxc: adjusted libvirt-lxc process to add restore mode to it.

When doing lxc migration or simply restoring the container from a saved state, we need restore the container from CRIU img files that we have stored in disk. In this patch, we should extend lxcContainerStart into a more generic one, that either starts a container from scratch or restores it from a snapshot.
