system (32bit) with latest updates, fresh rhel5.1 pv guest installation. when i
start up the guest it just "hangs". last line printed out on screen when using
xm console is from auditd. selinux is switched off in dom0. xend.log is

Comment 2 Chris Lalancette 2008-02-27 13:27:41 UTC 
This is probably not a hang, just a configuration issue.  Did you initially
install the guest with "virt-install --vnc", and then try to connect to it
afterwards with "xm console"?  If that is the case, the thing is that we don't
automatically setup xm console when doing a graphical install, since xm console
is really a serial terminal.  You should be able to get to it using virt-manager
or vncviewer.

If this is not the case, please get the full virt-install command line you used,
as well as the log from the guest console (/var/log/xen/console/guest-<name>;
you'll have to set it up in /etc/sysconfig/xend first).

yeah, the machine was installed using virt-install --vnc. How is it possible to setup the serial console afterwards, so that one can use xm console to get access to the machine?
Comment 4 Daniel Berrangé 2009-01-29 10:11:09 UTC 
In the guest you just need to edit /etc/grub.conf to add 'console=xvc0 console=tty'  and also edit /etc/inittab to turn on a agetty process on xvc0. This will cause boot messages to be sent to both text and graphical console, and also start a login prompt on the text console.
