I wonder if you replaced a non-Xen kernel with a Xen one, rather than
installing it as an additional kernel?
I tried with several different kernels but get the same result.
After some investigation I found that when I boot from the DVD
in
rescue mode and run grub from the command line I get this:
# grub
grub> root (hd0,0)
Filesystem type unknown, partition type 0x7
The file /boot/device.map contains:
(hd0) /dev/hdi
(hd1) /dev/sda
hd1 is my Windows disk.
Perhaps your map file doesn't really show what's considered hd0
and hd1.
Try issuing root (hd1,0), and see what difference it makes. You can
just type in (hd and hit the tab key, you'll get auto-complete
options
from what's available.
If something considers the order of the drives to be different,
they'llcount the other way around.
# grub
grub> root (<TAB>
grub> root (hd0,
Entering 0 gives me the "Filesystem type unknown..." error, entering
any other number gives me a "disk not found" error. I tried root
(hd1,0) but this doesn't work either.
If I try the auto completion with a kernel command, I get this:
# grub
grub> kernel /vmlin<TAB>
Error 17: Cannot mount selected partition.
I am guessing this is because the root command fails.
Steve,
what hardware do you have (e.g. motherboard, chipset, etc.)? To me it
seems pretty strange, that you harddrive (hd0) is /dev/hdi as hd0 should
be /dev/hda if I'm not wrong.
Did you install/boot with the all-generic-ide option? I'm just wild
guessing here.
