My configuration file is:
kernel = "/boot/vmlinuz-2.6.18-1.2849.fc6xen" ramdisk = "/boot/initrd-2.6.18-1.2849.fc6xen.img" memory = 64 name = "vm1" disk = [ 'phy:/dev/volgrp/vmdisk1,sda1,w','phy:/dev/volgrp/swdisk1,sda2,w' ] root = "/dev/sda1 ro" extra = "4"
Anybody has any ideia?
Thanks

Hello,
I'm trying start one guest OS, Fedora 5, on Xen 3 in Fedora Core 6, but during the booting process I get this error:
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)
My configuration file:
kernel = "/boot/vmlinuz-2.6.18-1.2849.fc6xen" memory = 64 name = "vm1" disk = [ 'phy:/dev/volgrp/vmdisk1,sda1,w','phy:/dev/volgrp/swdisk1,sda2,w' ] root = "/dev/sda1 ro" extra = "4"
What can I do?
Thanks!

This is booting a xenU right? not the dom0?

Your xenu kernel did not load the xenblk or xennet modules via initrd.
This is probably because you are booting a rootfs and not a disk image, and you are using the initrd from the kernel-xen image installed on the host (dom0), which got a re-tailored initrd image to suit its own requirements, which exclude those xen virtual drivers (since its dom0 not xenu).
Easiest fix is to unpack the initrd, add the two xen modules from /lib/modules/ add the insmod call in the "init" script of the initrd, and repack the initrd image.
The real fix is for redhat to always include xennet and xenblk drivers in the initrd for any kernel-xen initrd, even if it seems that the initrd is installed on the dom0. Really, the space saved in the kernel or in the initrd is not worth having to re-image the initrd for every new kernel-xen you people package up. The package kernel-xen is meant for dom and xenu, so please add the xennet and xenblk drivers in the initrd.
