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-2.6.19-1.2911.fc6xen"
ramdisk= "/boot/initrd-2.6.19-1.2911.fc6xen.img"
memory = 512
name = "opensuse102"
vif = ['']
#nics = 1
#dhcp = "dhcp"
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/hda2            swap                 swap

When I try to start Xen with:

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

I get this:

Hi Claus --

Almost certainly (believe me, based on hard-won experience)
your problem
is with the initrd.img defined in your VM config file:

ramdisk= "/boot/initrd-2.6.19-1.2911.fc6xen.img"

The root cause is probably the img file missing the
xenblk.ko driver. Just
rebuild the initrd using the "--with" switch to
include it.

If that doesn't work, you will need to look into the initrd
image and
possibly modify the init script; it may be trying to mount a
nonexistent
root device. But, my guess is xenblk.ko is missing. Search
through the
mailing list here or on xensource.com and it has been
discussed recently.

Good luck,


Dave

That's not enough, since you need to preload it. What I do
to create
initrd's for the guests (xenU's) on the dom0 is:

mkinitrd /boot/initrd-2.6.19-1.2911.fc6xenU.img
--preload=xenblk --with=xennet 2.6.19-1.2911.fc6xen

I've said it before and I'll say it again. Life would be
much simpler if
all the "xen" kernel tree images include xenblk
and xennet in the initrd.
The "space" won has been completely not worth the
time people lost over
this issue.
