VMs are now automatically connected to a virtual serial port, and we have exposed this serial port through the sipb-xen-console server. If you configure your VM to use this as a serial console, it is possible to remotely access your VMs serial console over ssh.

To enable the serial console for Debian or Ubuntu machines, there are excellent instructions at Note that if you installed your machine with the autoinstaller, this is already set up for you.
