OK guys; I am trying to concat both of what you guys have said...
1) On Host: brw-r--r-- 1 root root 98, 1 Oct 7 12:52 /dev/ubd0p1
2) On UML: brw-r--r-- 1 root root 98, 1 Oct 7 12:52 /dev/ubd0p1
3) /root/uml/linux-2.6.12.3/linux root=98:1
98:1=/backup/Slackware-10.1.ext2-795 eth0=tuntap,,,207.230.28.10 mem=64M
umid=795
It dies with:
Failed to open 'root_fs', errno = 2
VFS: Cannot open root device "98:1" or unknown-block(98,1)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(98,1)
<6>Stopping all CPUs...done
What am I doing wrong?

Okay, just noticed a BIG mistake. The "mknod -m 0660 /dev/ubd1p1 b 98 1"
should be "mknod -m 0660 /dev/ubd1p1 b 98 17". I hope this is vaguely
related to what you're asking...

Derek,
I haven't done this with the actual root filesystem. I have done this
with "data" filesystems. However, I would suspect something like the
following (typing from memory, so take with a grain of salt):
./linux ubd0s=/path/to/currentimage ubd1s=/path/to/partitioned/image
[other options] -s
[boot into single-user mode]
# fdisk /dev/ubd1
[create your partition table and save it]
# mount -o remount,rw /
# mknod -m 0660 /dev/ubd1p1 b 98 1
# mount /dev/ubd1p1 /mnt
# for dir in `ls |egrep -v 'lost+found|mnt'` do cp -a $dir /mnt/; done
# umount /mnt
# shutdown -h now
Then give it a try with something like:
./linux ubd0s=/path/to/partitioned/image [other options]
The key is creating an image with a partition table. This should also
eliminate the following warnings at boot:
ubda: unknown partition table
ubdb: unknown partition table
Let us know how it goes!

How can I use over 16 UBD devices? I have read in the mailing
lists that
you can create partitions:
brw-r--r-- 1 root root 98, 1 Oct 7 12:52 /dev/ubd0p1
However; I cannot mount the above device while UML is booting. Can
someone provide me with some direction?
