Hi all,

On xen + openstack diaboli-3 when running an instance with the generic ubuntu UEC images  from http://wiki.openstack.org/RunningNova#Registering_the_image  I am seeing the following:

[    0.210681] VFS: Cannot open root device "xvda" or unknown-block(0,0)
[    0.210691] Please append a correct "root=" boot option; here are the available partitions:
[    0.210708] ca00            8192 sda driver: vbd
[    0.210720] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

This is on debian 6 (x86-64), is this a location that exists for others?

Here is the xml that was used to create this instance. It looks pretty standard. Any xen users out there encountered this?
