[Xen-users] DomU booting problem.

I am new to Xen and not a pro Linux guy. So, I am having bit of rough
ride setting up Xen.



Xen (2.0.7) and Dom0(2.6.11.12-Xen0) are booting alright. However, when
I am not able to start DomU (ttylinux - standard download - no changes
made). It stops at IP Config. Here is console log, the DomU config file,
as well my main grub.conf. Quick help is really appreciated. Thanx



root@localhost xen]# xm create ttylinuxVM -c

Using config file "ttylinuxVM".

Started domain ttylinux, console on port 9601
