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!
