Thanks George. It does.

All records (and memories) of my fedora setup are long lost.

Guest is PV.  All bridging, etc. is predefined in Dom0.  Not knowingly 
using any scripts, virt-, qemu-, etc. Everything is manual via "xl". 
Using xen-4.5-amd64 with ubuntu's kernel 3.19.0-16-generic.
### config
name        = 'MIKE'
kernel      = '/etc/xen/VMs/boot/vmlinuz-4.4.0-18-generic'
initrd      = '/etc/xen/VMs/boot/initrd.img-4.4.0-18-generic'
vcpus       = '3'
memory      = '6144'
root        = '/dev/xvda1 ro'
disk        = [
  'phy:/dev/VMs/MIKE,xvda1,w',
  'phy:/dev/VMs/MIKEs,xvda2,w',
]
vif         = [
  'mac=00:16:3E:01:B3:11,bridge=LAN',
  'mac=00:16:3E:09:47:C1,bridge=SND',
]
vbf         = [ 'sdl=1,vnc=1,vncdisplay=0' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

### this process exists; I think it is started by xl when the guest is 
created:
/usr/bin/qemu-system-i386 -xen-domid 0 -xen-attach -name dom0 -nographic 
-M xenpv -daemonize -monitor /dev/null -serial /dev/null -parallel 
/dev/null -pidfile /var/run/qemu-dom0.pid
Since correcting the vbf line it appears to run more smoothly be there 
is still some jerkiness.
I looked at the man page for "qemu-system-i386".  How are those options 
passed in?  Some of them such as "-nographic" look interesting.
Anything else I can provide?

Thanks,
Mike Wright
