[Xen-devel] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Hi, While booting the Xen 3.0.3 installation I get a kernel Panic VFS: Cannot open root device "hde1" 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) I tried to install with the binaries and I also tried to compile the sources. But always the same failure! My menu.lst from Grub: Not working Xen Boot: title Xen 3.0 / XenLinux 2.6 kernel /boot/xen-3.0.gz module /boot/vmlinuz-2.6-xen root=/dev/hde1 ro console=tty0 Working Debian Boot: title Debian .... root (hd0,0) kernel /boot/vmlinuz-2.4.27-2-386 root=/dev/hde1 ro initrd /boot/initrd.img-2.4.27-2-386 savedefault boot mount command tells me: /dev/hde1 on / type ext3 (rw,errors=remount-ro) ...so the root=/dev/hde1 must be correct, I think! Anyone an idea? Thx for Help!

You will need ext3 support compiled into vmlinuz-2.6-xen kernel. I suspect it''s compiled as a module. Make sure that your kernel configuration file says: CONFIG_EXT3_FS=y recompile, copy the kernel and try again. Does it help?
