When I try to mount loop device in a linux container, I got the following error message: mount: Could not find any loop device. Maybe this kernel does not know about the loop device? (If so, recompile or `modprobe loop'.)

I wonder how to enable mount loop device in LXC using libvirt LXC driver?

You don't want to try to setup loop mounts yourself - tell libvirt todo it in the XML eg <filesystem type='file'> <source file='/some/file/image'/> <target dir='/some/mount/point'/> </filesystem> and then libvirt will create a loop device and mount it. If you just want the loop device and not mounted, then use <block type='file'> instead.
