Re: [Xen-users] Kernel Panic on trying to boot domU

["Girish V" <girish.xen@xxxxxxxxx>]

I checked by mounting and chrooting to the guest image and it worked. In fact I have used this same image with other versions of Xen (3.1.3) for instance and it works - so I am not sure if it is a problem with the image.
Girish

Weiming, to answer your question, I created the guest image following the guidelines in the xen user manual. And that is the same way I have created guest images for other versions of Xen.

You can check
your domain U filesystem
with the commands:

mount -o loop /second/fc6_domudisk /mnt
chroot /mnt
(try to work with the chrooted system)
ls -l /sbin/init # (in chroot)
