I am using 2.6.18-1.2869.fc6xen and xend starts fine.
However, I am trying to create the guest and running
into the block device problem. I got the image from
jailtime.org for fedora6. 

My config file: 
kernel = "/boot/vmlinuz-2.6.18-1.2869.fc6xen"
memory = 64
name = "fedora.fc6"
vif = [ '' ]
dhcp = "dhcp"
disk = ['file:/etc/xen/fedora.fc6.img,sda1,w',
'file:/etc/xen/fedora.swap,sda2,w']
root = "/dev/sda1 ro"

I always ran into this.

VFS: Cannot open root device "sda1" or
unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root
fs on unknown-block(0,0)


With lots of search and reading, I kinda trying to
understand its some kind of problem with udev. My
udevd seems to be working fine. 
I tried to create block devices manually using mknod
but has no change in the error whatsoever.
I tried to look into logs xend-debug.log and xend.log
but it doesn't specify anything about the particular
error.

Seems like this was the problem with some kind of
configuration with the posts I have read online but
was not able to get key. 

Any help is greatly appreciated.
Thanks,
Ski
