I've been using Xen on FC4 and FC5 (and CentOS). I'm trying to ugprade to FC6. However, I'm having problem getting a CentOS domU to boot. The guest is complaing that it can't mount the root file system. This is my xen cfg file: ---- kernel = "/boot/vmlinuz-2.6.18-1.2798.fc6xen" memory = 1536 name = 'dsv' vcpus = 2 vif = [ 'bridge=xenbr0' ] disk = [ 'phy:xenvg/dsvdb2,sda1,w', 'phy:xenvg/dsvroot,sda2,w', 'phy:xenvg/dsvswap,sda3,w', 'phy:xenvg/dsvusr,sda4,w', 'phy:xenvg/dsvvar,sda5,w' ] root = '/dev/sda2 ro' extra = "3" on_reboot = 'restart' on_crash = 'restart' on_reboot = 'restart' ---- On bootup, this is the error: VFS: Cannot open root device "sda2" 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) Nothing gets written to the xen log files. I tried with and without an ramdisk. I read on the net that dom0 and domU can use the same kernel. Is this not true. I don't see a kernel-xenU kernel so this must be true. What am I missing? Thanks for help any.
