Can you check following entrys:

disk    = ['phy:vm_volumes/root.dhcp1,sda1,w',

disk    = ['phy:/vm_volumes/root.dhcp1,sda1,w',

I think the system can not find the images, test it plz. 

I hope this will help :-)

Bayesian Filter detected spam


        I have just installed xen 3.0.1 in a debian sarge system. After some 
days of trying with binary distribution of xen, I found a debian  sarge 
backport at http://packages.debianbase.de/sarge/i386/xen3, and this is the one 
I have installed.

        I have compiled my dom0's custom kernel (I had to do it because the 
"standard" one doesn't boot in my dell poweredge 750). Basically, the 
difference between the standard and mine is that I have included megaraid in 
the kernel, not as a module). With this custom kernel I have running my dom0.

        The problem I have is what domU. I created a debian system for domU 
(with debootsrap) and I compiled a new custom domU kernel. This kernel is the 
same as dom0 but I have also include raid support in the kernel (not as a 
module, in dom0 I have it as a module).

        The problem I have is that I can't boot this domU, because I get the

VFS: Cannot open root device "sda1" or unknown-block(8,1) Please append a 
correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount 
root fs on

        I have tried to boot domU with the same kernel as dom0, but I get the 
same behaviour.

        Any help?

PS: attached is the full log I get when I try to boot domU and the 
configuration of this domU.
