[Fedora-xen] XEN Problem with root device

Hi all!

At first I have to admit that I am very inexperienced in using XEN!
What I try to do is get OpenSuse 10.2 working on my FC6 Station.
To do that I did the following steps:

1)Installed the XEN Kernel: 2.6.19-1.2911.fc6xen

2)Installed OpenSuse 10.2 on my girlfriends Laptop

3)made a complete image of the installation and put it in my home:

/home/user/opensuse102xen.img

4)created an suse.xen.cfg:

kernel = "/boot/vmlinuz-2.6.19-1.2895.fc6xen"
memory = 512
name = "opensuse102"
vif = ['']
#nics = 1
#dhcp = "dhcp"
disk = disk = ['file:/home/rehcla/opensuse102xen.img,xvda,w'] 
root = "/dev/xvda ro"

5)did edit the /etc/fstab in the Image:


/dev/xvda            /                    ext3       acl,user_xattr
1 1
#/dev/hda1            /windows/C           ntfs
ro,users,gid=users,umask=0002,nls=utf8 0 0
#/dev/hda2            swap                 swap       defaults
0 0
proc                 /proc                proc       defaults
0 0
sysfs                /sys                 sysfs      noauto
0 0
debugfs              /sys/kernel/debug    debugfs    noauto
0 0
usbfs                /proc/bus/usb        usbfs      noauto
0 0
devpts               /dev/pts             devpts     mode=0620,gid=5
0 0


When I try to start Xen with:

"xm create opensuse102  -c suse.xen.cfg"

I get this:


Using config file "./suse.xen.cfg".
