<BR>
On xen + openstack diaboli-3 when running an instance with the generic ubuntu UEC images from <a href="http://wiki.openstack.org/RunningNova#Registering_the_image">http://wiki.openstack.org/RunningNova#Registering_the_image</a> I am seeing the following:<BR>
<BR>
</SPAN></FONT><SPAN STYLE='font-size:11pt'><FONT FACE="Courier, Courier New">[ 0.210681] VFS: Cannot open root device "xvda" or unknown-block(0,0)<BR>
[ 0.210691] Please append a correct "root=" boot option; here are the available partitions:<BR>
[ 0.210708] ca00 8192 sda driver: vbd<BR>
[ 0.210720] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)<BR>
</FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><BR>
This is on debian 6 (x86-64), is this a location that exists for others?<BR>
<BR>
Here is the xml that was used to create this instance. It looks pretty standard. Any xen users out there encountered this?<BR>
