Bug#771675: systemd: machinectl: Failed to get container bus: Input/output error

[Mario Lang]

Package: systemd
Version: 215-7
Severity: minor

Trying to access a container with "machinectl login" fails.
But booting the container manually gives a login prompt.

root at host:/# mkdir /var/lib/container
root at host:/# debootstrap jessie /var/lib/container/debian-jessie
I: Retrieving Release I: Retrieving Release.gpg
I: Checking Release signature
...
I: Base system installed successfully.
root at host:/# systemd-nspawn -D /var/lib/container/debian-jessie
Spawning container debian-jessie on /var/lib/container/debian-jessie.
Press ^] three times within 1s to kill container.
/etc/localtime is not a symlink, not updating container timezone.
root at debian-jessie:~# exit
root at fzidpc73:/# systemd-nspawn -bD /var/lib/container/debian-jessie
...
Debian GNU/Linux jessie/sid fzidpc73 console

fzidpc73 login:

OK, so the container boots with systemd-nspawn, but:

root at fzidpc73:/# systemctl start systemd-nspawn at debian-jessie.service
root at fzidpc73:/# machinectl list
MACHINE                          CONTAINER SERVICE
debian-jessie                    container nspawn

1 machines listed.
root at fzidpc73:~# machinectl login debian-jessie
Failed to get container bus: Input/output error


I am confused, possibly because I don't fully get all the technology
involed yet.  machinectl *sees* the running machine, but it fails to
connect to it, with a rather generic error message.
