[Xen-users] Starting basic HVM -- where am I going wrong?




I've been using Xen strictly for PV for a while now, but I recently upgraded to 
hardware capable of HVM domUs.   I'm trying to get a really basic HVM instance 
going so I can get my hands around making them work, in anticipation of using 
one to run a BSD to act as a firewall for other domUs on the machine.  (I like 
PF.)  Also, I might need run windows at some point, I suppose.

I've created a very simple HVM configuration file, starting with a larger one 
and paring down trying to figure out where the problem is.   It says it starts 
up, but it doesn't show up in 'xm list'.

The dom0 is running ArchLinux, and I'm running a Xen 4.1.1 package I assembled 
and compiled myself.  PV dom0's are running fine in this configuration, also 
with a VNC vfb.   I'm also testing this hardware out on a server with opterons 
(as opposed to xeons) and I'm getting the same result, so I don't think it's 
the hardware.

Been at it a couple days, so any pointers as to what I'm doing wrong would be 
helpful.
