RE: [Xen-devel] Problems booting 32-bit Domain 0 and 32 bit Xen on x86_64 hardware

["Subrahmanian, Raj" <raj.subrahmanian@xxxxxxxxxx>]

My mistake again.
It was indeed the compatibility issue.
I was trying to run the wrong Dom0.

Sorry, my mistake. I am having this problem with the matched dom0 (the 2.6.12. 
kernel). 
So, I don't think that compatibility is the issue.

You need to run a matched dom0. Older dom0's (like your 2.6.11 must be) 
will not work.

We don;t keep backward compatibility in the unstable tree, only during 
stable series.
