libvirt users - Apr 2013 - /dev/tty only on a new container

Hi folks :),
I migrated the host from the Debian Squeeze to Ubuntu 12.10. Old
containers work but I can't use the ssh command, /dev/tty is missing.
On a new container, /dev/tty is here. The libvirt configuration is the
same.


Any ideas?
Thanks.

Libvirt never creates any /dev/tty node, and /dev is a tmpfs created
each time the container starts, so the only reason a /dev/tty could
exist is if something you are running inside the container created it.

The console devices libvirt creates are /dev/tty0, /dev/tty1, etc,
with tty0 obviously being the first/primary one.

Regards,
Daniel

Hi Sebastien.

Which SSH connectivity did you lose? From the hypervisor to the VM's? Did
you started the VM's? Can you telnet TCP 22 port on the VM from the
hypervisor? Are you able to use livbirt-manager to connect first to the
hypervisor then (in case it's configured) to the VNC service running on the
VM in order to access to it through a GUI?

Regards.

Javier

Hi,
I'm back again with the same issue. After updated the server to Ubuntu
13.04, all LXC containers lost the /dev/tty device (can't create it
manually). Same issue with a *fresh* LXC container.
The "funny" thing is the container works fine if launched by
lxc-start, so the problem seems to be with the container
configuration. I'm lost. Ubuntu bug or just stupid brain?
