Both ways I get the following error: error: Failed to start domain testdeb error: internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=df03b2ce-725a-42e2-39e4-d646be8facb3 LIBVIRT_LXC_UUID=df03b2ce-725a-42e2-39e4-d646be8facb3 LIBVIRT_LXC_NAME=testdeb /sbin/init error receiving signal from container: Input/output error The error message after the internal error guest failed to start", changes between runs. The following mount is left behind, one for each time I've tried to start the domain: libvirt on /run/libvirt/lxc/testdeb.fuse type fuse (rw,nosuid,nodev) And lastly the following is left behind: ls -l /var/run/libvirt/lxc/ total 0 drwxr-xr-x 2 root root 40 Mar 23 23:26 testdeb.devpts drwxr-xr-x 2 root root 40 Mar 23 23:26 testdeb.fuse srwx------ 1 root root 0 Mar 23 23:31 testdeb.sock #
