Hi all,

I''m trying to install xen-unstable on ubuntu. I downloaded the tarball
from
the download page. Everything goes on fine until the compilation. However
when I boot xen-unstable this the error I get:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block
(0,0)

I guess this has something to do with the ram disk image. What I am doing
currently is:

depmod -F /boot/System.map-2.6.16.13-xen 2.6.16.13-xen
mkinitrd -o /boot/initrd-2.6.16.13-unstable 2.6.16.13-xen

The readme however says to do this:

mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod
initrd-2.6.16.13-xen.img 2.6.16.13-xen

But when I do this, mkinitrd gives an error regarding illegal options. The
only ones it provides are:

-d confdir         Specify an alternative configuration directory.
-k                     Keep temporary directory used to make the image.
-m command  Set the command to make an initrd image.
-o outfile          Write to outfile.
-r root              Override ROOT setting in mkinitrd.conf.

Please help me on how to go about booting xen-unstable. I desperately need
to get it working!
