Re: [Fedora-xen] Newby Help



Hello,

I can offer some input from my own experiences regarding mounting root.

I changed the root clause to:

root = "/dev/xvda1 ro"

, which changed the error to:

VFS: Cannot open root device "xvda1" or unknown-block(0,0)
Please append a correct "root=" boot option

I'm unclear whether the problem is in creating the virtual disk or in
being able to mount it after it's been created.

I found that the default initrd did not contain the xenblk driver and so it could not access the root filesystem. See here:

http://lists.xensource.com/archives/html/xen-users/2008-03/msg00000.html

You might even want to use the --preload option of mkinitrd. My exact mkinitrd was:

#  mkinitrd -v --preload=sd_mod --preload=xenblk --with=xennet --with=xenblktap\
 --with=xenbus_be /tmp/test `uname -r`

Then I copied /tmp/test to /boot/initrd-2.6.21.7-2.fc8xen.img. This worked for me - YMMV.

Cheers,

Fred.
