HVM install config:

name = "ubuntu32"
memory = "256"
disk = [
  'file:/opt/xen/ubuntu14.04.img,hda,w',
  'file:/opt/xen/ubuntu32.img,hdb,w'
]
vif = [ 'mac=02:00:00:00:01:dd, bridge=bridge0', ]
vcpus = 1
builder='hvm'
vfb= [ 'type=vnc' ]
on_crash="destroy"
on_poweroff="destroy"
on_reboot="restart"

Post install

name = "ubuntu32"
memory = "256" # 1870 Matches Rackspace '2G' server
disk = [ 'file:/opt/xen/ubuntu32.img,xvda,w' ]
vif = [ 'mac=02:00:00:00:01:dd, bridge=bridge0', ]
bootloader = "/usr/pkg/bin/pygrub"
vcpus = 1
