After creating fresh LXC based on Debian Jessie, on a Ubuntu 14.04, systemd-journal eats all CPU available.

lxc-create -n jessie -t debian

As mentioned in Debian wiki:

Add to container's config /var/lib/lxc/{container}/config:

lxc.autodev = 1
lxc.kmsg = 0

and comment out /var/lib/lxc/{container}/rootfs/lib/systemd/system/getty@.service


Then restart container. Same problem with Fedora host mentioned here

  • per the above mentioned Fedora post, you also need to: Delete ${LXC_PATH}/${container}/rootfs.dev/kmsg – David H. Bennett Feb 16 '16 at 16:31
  • Now that the kmsg parameter is no longer supported in lxc, is there a way to solve this issue without it @Tombart? – Quint Jan 15 '19 at 16:40
