I had not anticipated a failure there? And it is failing in remount? Oh that is interesting. That implies that there is some flag of the original mount of /proc that the remount of /proc/sys is clearing, and that previously The flags specified are current rdonly,remount,bind so I expect there are some other flags on proc that libvirt-lxc is clearing by accident and we did not fail before because the kernel was not enforcing things. What are the mount flags in a working libvirt-lxc?
