Create a container like so: $ sudo lxc-create -t ubuntu-cloud -n base -- -S ~/.ssh/id_rsa.pub -r trusty Start it: $ sudo lxc-start -d -n base Attach to the container: $ sudo lxc-attach -n base Try to login (fails with too many authentication errors): $ ssh -i ~/.ssh/id_rsa ubuntu@`dig @10.0.3.1 base` -v Look at logs (/var/log/auth.log) on attached container and see: - error: Could not load host key: /etc/ssh/ssh_host_ed25519_key Work around by manually creating key: $ sudo /usr/bin/ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -N '' $ sudo service ssh restart Login now works.
