This seems to have stopped working with latest kernel upgrade. To replicate failure... net1# lxc-create -t ubuntu -n test Checking cache download in /var/cache/lxc/saucy/rootfs-amd64 ...

Seems like this did show up as enabled in previous kernel. Reading other bugs reports, this seems to be okay + will be fixed upstream + I mention it here because it's a difference. net1# lxc-checkconfig | grep -v enabled Kernel configuration not found at /proc/config.gz; searching...
