Ok, i just tried this on RHEL 5 (3.0.3) to see what the issue is.
I installed the normal kernel on domU, like you did.
Adjusted the config to go off of the HVM and 64 bit device_model.
It still just hung. Then I realized the key difference between that
file and my other HVM's. Its the vif line. I had to specify the type
of "ioemu"
vif = [ 'mac=00:16:3e:3f:a9:f5, type=ioemu, bridge=xenbr1', ]
I ran into partition problems though and get a kernel panic immediately
after boot because the PV domU was using xvda not hda. I'm running into
more and more issues because the domU guest is fedora which uses labels
for disks. It looks like my initrd is not pointing to the correct
devices and I'll need to change my fstab and grub.conf.
Its still not working, but it at least gets you passed the step that
your on. I don't know if i'll have time today to work through the
partition issues or not, but if you are running a non redhat flavor on
your domU you might not even have these problems.
my config:
name = "test"
memory = "256"
vcpus=1
apic=1
acpi=1
pae=1
builder = "hvm"
device_model = "/usr/lib64/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
disk = [ 'file:/xen/linux/f7/test/test.img,hda,w', ]
vif = [ 'mac=00:16:3e:4f:04:01, type=ioemu, bridge=xenbr3', ]
#vfb = ["type=vnc,vncunused=1,vnclisten=0.0.0.0"]
vnc=1
vncunused=1
#vncdisplay=7
on_reboot = 'restart'
on_crash = 'restart'
