We recently installed a machine with Proxmox 4 to try the new LXC system. I have a question regarding storage. With OpenVZ the filesystem of a container would be in /var/lib/vz/templates/<vmid>/. This was ideal for quick maintenance and backups. We could just backup the proxmox host instead of all the separate VMs. With LXC there are raw disk images in /var/lib/vz/images/<vmid>/. Besides not being able to properly backup those images it also adds additional overhead (a filesystem on a filesystem). Is it possible to use the OpenVZ chroot style storage instead of separate disk images with LXC? If so, how?
