I used a file-backed VBD for the virtual disk of my VM.
I formatted it
as ext3, I mounted it in a directory and I copied directories from my
linux-domain0 installation as a test.
I used this configuration file:
kernel = "/boot/vmlinuz-2.6.16.29-xen_3.0.3.0"
ramdisk = "/boot/initrd-
2.6.16.29-xen_3.0.3.0.img"
memory = 256
name = "dominio1"
vif = [ '''' ]
kernel''s and ramdisk''s paths are referred to the relative path
to the
files in my VM.
I gave: xm create -c myconfig vmid=1
but the creation
of a new domain crashes.
last output lines are:

volumes

No
volume groups found

now I post the xend.log
too:

and this is the
etc/fstab in my vm(perhaps I made some mistakes in it!?!):
/home/sibilia/dominio1 / ext3 defaults

sysfs /sys

I''ve only cut some lines from the original
/etc/fstab.
Do you think It''s a problem whit config files?

If you have an "uncomplicated" system, it''s quite possible to have a "merged" Dom0/DomU initrd, but as soon as you have something a bit more complex (e.g. using LVM), it starts to be complicated to make the initrd work on both DomU and Dom0 at the same time. Of course, there''s also the drawback that you load drivers that aren''t needed for "the other side", but that''s a smaller issue than the fact that the initrd just plain doesn''t work right for the two domains if they are not "similar enough". -- Mats> > Regards > Dominik > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Now, to your domain config file (in domain 0), you should add: disk = [''tap:aio:/home/sibilia/dominio1,sda1,w''] Now try booting the domain, does this work better?

I''ve modified my etc/fstab in the guest as you said. I had already the disk= line in my guestdomain config (I had only dropped it when pasting here). I didn''t consider for now yuor useful advice about boot loader in the guest. However, something seems still to be wrong! My final output, before kernel panic, is the same: ..... Making device-mapper control node Scanning logical volumes Reading all physical volumes. This may take a while... No volume groups found Activating logical volumes Unable to find volume group "VolGroup00" Creating root device. Mounting root filesystem. mount: could not find filesystem ''/dev/root'' Setting up other filesystems.

Do you think It''s only because of the kind of kernel I used (that is that one of domain0)? ----Messaggio originale---- Da: mark. williamson@cl.cam.ac.uk Data: 13-giu-2007 7.36 PM A: <xen-users@lists. xensource.com>, "andrea15@tin.it"<andrea15@tin.it> Ogg: Re: [Xen-users] kernel panic when creating domainU On Wednesday 13 June 2007, andrea15@tin.it wrote:> I used a file-backed VBD for the virtual diskof my VM.> I formatted it > as ext3, I mounted it in a directory and Icopied directories from my> linux-domain0 installation as a test. > Iused this configuration file:> kernel = "/boot/vmlinuz-2.6.16.29-xen_3.0.3.0"> ramdisk = "/boot/initrd- > 2.6.16.29-xen_3.0.3.0.img" > memory= 256> name = "dominio1" > vif = [ '''' ]You don''t have a disk = line in there - you need one or it won''t see any disks to boot off.
