Hi

 I have a couple of questions:
2. How do I setup a dom0/domU in order to get a tty login?

Not sure if it's quite what you're after, but I use the following in / etc/inittab:

1:2345:respawn:/usr/sbin/xm top > /dev/tty1
2:23:respawn:/usr/sbin/xm console dom1 > /dev/tty2 < /dev/tty2 2>&1
3:23:respawn:/usr/sbin/xm console dom2 > /dev/tty3 < /dev/tty3 2>&1
4:23:respawn:/usr/sbin/xm console dom3 > /dev/tty4 < /dev/tty4 2>&1
5:23:respawn:/usr/sbin/xm console dom4 > /dev/tty5 < /dev/tty5 2>&1
6:23:respawn:/usr/sbin/xm console dom5 > /dev/tty6 < /dev/tty6 2>&1
7:23:respawn:/usr/sbin/xm console dom6 > /dev/tty7 < /dev/tty7 2>&1
8:23:respawn:/usr/sbin/xm console dom7 > /dev/tty8 < /dev/tty8 2>&1
9:23:respawn:/sbin/getty 38400 tty9

This gives me 'xm top' on the main console, console access to my guests using ALT-F2..ALT-F8, and a host login prompt with ALT-F9.

There's room for improvement... if a guest is down, the guest console spits out an endless stream "Domain xxx isn't running" - I'm thinking of wrapping the xm call in a script that will deal with that quietly.

HTH, Itai
