hi everyone,

how can I use a LV created by lxc in libvirt guest domain? You know, you lxc-create with LV as backstore for a container(ubuntu in my case) and now you want to give to libvit. That, I thought would be a very common case but I failed to find a good howto on how one: lxc-create(lvm) => let libvirt take control over it. Or it's not how you would do it at all? many thanks, L.

lxc creates containers whereas lib-virt deals with full blown virtual machines. The two are not the same. Processes inside LXC containers actually run in the host system, i.e., uses the hosts kernel. They are isolated and protected from the rest of the system by features in the kernel. Virtual machine are completely independent systems. A VM runs its own kernel and the processes running inside a VM are not visible to the host system at all. Hope this makes some kind of sense. In short, I don't think what is in the LV created for a LXC container is sufficient for it to run as a VM.
