First we need to understand what the problem is. I wasn't aware of this
issue before you started a thread yesterday and nothing meaningful
appears in any of the logs posted.

Now I am trying to reproduce the problem but so far I didn't have any
luck: I am testing with the same kernel config and VM config you use
with plain Linux 3.0.0 rc7, I tried both xen 4.1.0 and xen 4.1.1 but I
still can start hvm guests with no troubles.

However all my tests are on Debian 6.0.1, I am downloading alpha 2 to
see if I can reproduce the bug there.
