Hello,

I've finally been able to install Xen (version 3.4 with kernel 2.6.18) and booted the xen kernel. Now I'm trying to create a VM that uses an image file as its disk, but a few seconds after I boot the VM it stops with this message:

[root@localhost xen]# xm create -c xmexample1 vmid=1

......

No filesystem could mount root, tried: ext2

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)

Here is the config file:

-------------------------------

kernel = "/boot/vmlinuz-2.6.18.8-xen"

memory = 400

name = "ExampleDomain"

vcpus = 4

vif = [ 'mac=00:16:3e:00:01:01, bridge=br0' ]

disk = [ 'file:/home/xen/image,sda1,w' ]

root = "/dev/sda1 ro"

extra = "4"

--------------------------------

That image, /home/xen/image, was created by a previous Xen installation (it came with my Fedora 7 distro with virt-manager, so I did not have to manage config files. I want to boot from it again using the newest Xen)

Thanks
