Try to add

root        = ''/dev/xvda1 ro''

or if your problem still exists, try:

disk = [ "phy:/dev/sda6,sda1,w", "phy:/dev/sda7,sda2,w" ]
root        = ''/dev/sda1 ro''

Bye,
Fabian

Re: [Xen-users] xen guest dont find root file system

tnk Fabian,
in both cases I get:

mount: Mounting /sys on /root/sys failed: No such file or directory
mount: Mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn''t have /sbin/init

looks like there is no os installed on your root-partition. How did you 
create your DomU?

Here some keywords to ask google:

debootstrap
xen-tools
hvm to pv

Fabian
