Re: [Xen-users] problem in booting additional domains: "Error: Adding extent to vbd failed: error 8"

[Ardalan K <ardalanbiz@xxxxxxxxx>]

Thanks Marcus,
I had tried what you said and that had given me the
same error. By the way, the documentation section of
xen (section 5.3) also does n't put /dev. I think my
problem with LVM originates from the fact that domain0
does n't have LVM modules. It gives me the following
error "LVM driver/module not loaded?". I don't have
this problem when I boot with the plain Linux option
from Grub and that's how I set up these logical
volumes. I tried to configure linux-2.6.11-xen0
(assuming this is the domain0 kernel) to have all the
LVM and sound modules that my Suse 9.0 has but after I
boot with xen, domain0 still does n't recognize LVM
and my sound card. Please tell me if I am configuring
the wrong kernel or if I am doing something wrong.
Should I include these modules as part of kernel(not
as modules)? Do I have the right initrd? Finally, I
gave up on LVM and tried exporting physical devices
(my hda7 partition) as VBD   AND THAT WORKED! :D

I appreciate if anyone can tell me how I can get
LVM/sound working. 

Regards,
Ardalan
