Change this to 'sdl=0' and add 'vnc=1'. This will make Xen start a<br>VNC server in the Dom0 host to which you can connect & view the guest<br>installer.</blockquote><div><br>It didn't start anything that listens on any port on the Dom0 machine. I added "vncviewer=1" and that started a vncviewer but I'm not clear how am I supposed to connect to it.
<br><br>Anyway, from more googl'ing I was reminded about "xm console" and attached below is the output from when I invoke it - it looks like the guest kernel doesn't find some important devices and then just sits there without completing the boot process.
<br><br>From Googl'ing the error it sounds like the initrd (or the /lib/modules directory on the Xen Guest's filesystem?) is missing some xen-related device modules but installing <a style="" href="http://mirror.bytemark.co.uk/fedora/linux/releases/7/Fedora/x86_64/os/Fedora/kernel-xen-2.6.20-2925.9.fc7.x86_64.rpm">
kernel-xen-2.6.20-2925.9.fc7.x86_64.rpm</a> and trying to use the kernel and initrd image from there just causes the guest to boot in a loop too fast and causing Xen to just destroy it.<br><br>What could be the problem now?
