Xen Console

Command to connect to a Xen console from a shell prompt:

# xm console guestname

This is similar to telnet'ing into a serially connected terminal server. The bad news is that the exit command drops you to the guest's login prompt, not Dom0's shell prompt. Solution:

apollo.terran.lan:   Ctrl+]   [root@adama xen]#

That character sequence is press and hold the control key, and tap the close bracket key. (Yes, it does it up displaying as a single line in the terminal window.)
