Hello, I'm trying to play with lxc, but I'm unable to start a container created with lxc-debian in two diferent linux systems I have. linux-2.6.29-gentoo-r5 x86_64. linux-2.6.28-11-generic ubuntu x86_64. Lxc version 0.6.2, git checkout of yesterday. lxc-debian sucessfully creates a new container: root@feynman:/mnt# lxc-info -n x86deb 'x86deb' is STOPPED root@feynman:/mnt# lxc-start -n x86deb lxc-start: Invalid argument - failed to fork into a new namespace lxc-start: failed to spawn '/sbin/init' I only have the ubuntu machine acessible now, but my problem on the gentoo was the same I believe. In this ubuntu machine, lxc-showconfig gives me this: root@feynman:/mnt# lxc-checkconfig Kernel config /proc/config.gz not found, looking in other places...
