Xen users - May 2009 - RE: Cannot open root device "sda1" or unknown-block ..

Hello,

Try with hda1 or xvda1. I remember getting that a while ago and replacing sda
with hda… but that could be wrong. Try it anyways!

You''re booting Ubuntu jaunty using kernel in dom0 but WITHOUT ramdisk?
Are you sure all necessary drivers are included?
