I am trying to replace uml with xen, but I cant get the unpreviliged Domains
booting..
Ive tested a cuple of filesystems in a file (ext3 or xfs formatted) and Ive also
tried the ttylinux-xen image. But I always get this error:
VFS: Cannot open root device "hda1" or unknown-block(3,1)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)
 
 
 
Ive no ideas what else I could try, can somebody give me an hint please?
 
 
 Are you using the prebuilt unprivileged-domain kernel image? If so, the 
one in 2.0.1 at least (maybe others, not sure) has devfs support 
enabled. This breaks things. I suggest you rebuild your domU kernel 
_without_ devfs support, and it should work correctly. I had this same 
problem when I began playing with Xen, but after rebuilding the kernel 
as I mentioned, it all worked correctly.
