[libvirt-users] Failed to mount devpts

Hi all, I've been trying to start a LXC container using libvirt, but I keep getting `Failed to mount devpts on /vservers/quantum/fs/dev/pts: Invalid argument'. I found a similar thread on the mailing list a couple months ago (https://www.redhat.com/archives/libvirt-users/2012-January/msg00052.html), but the solution posted didn't work for me. Anyone has any ideas? Extra Info: Libvirt version Compiled against library: libvir 0.9.12 Using library: libvir 0.9.12 Using API: LXC 0.9.12 Running hypervisor: LXC 3.3.5 Host is running F16, and the domain xml can found at http://pastebin.com/yWXQviVy Best regards, Marco
