Sergio,

I just tried this config and it booted fine:
name = "Belldandy"
maxmem = 256
memory = 256
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib64/xen/bin/qemu-dm"
disk = [ "phy:/dev/SystemsVG/Belldandy,hda,w" ]
vif = [ "mac=00:16:3e:29:65:46,bridge=xenbr0,script=vif-bridge" ]
vnc = 1

Attached is the generated virsh xml from the above.

I'm going to tinker with this for a bit to try and figure out what 
difference from the previous config is actually the cause of the issue. 
  I just had the other, formerly working VM, bail with the same symptoms 
once I got this one work.  The workaround is nice but I definitely want 
to isolate this bug now.

Thanks everyone for all the help!

Aaron
