I have an ''interesting'' problem. I just upgraded from 3.0.0_pre20041027 to 3.0.0_pre20051128 (this is on a Gentoo platform). I recompiled both the Dom0 and DomU kernels. Now on booting (in this case my test ttylinux) domU I get. VFS: Cannot open root device "sda1" or unknown-block(0,0) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) The config is unchanged from the (working) previous version: kernel="/root/vmlinuz.domU" memory = 32 name = "ttylinux" nics = 1 root = ''/dev/sda1'' disk = [''phy:/dev/vg-xen/ttylinux,sda1,w''] Had no problems with previous version, now get the unable to find root problem. Does anyone have any clues as to what could be causing this, or where I can look to find more info to post (there''s not much in the log except the crash of the domain)?
