Hi Richard, I found out that I can boot the domU if I change it to a HVM. e. g. Comment the line # bootloader = "pygrub"
and add the line builder = "hvm" in the config file. Now the domU works as expected, but it is a HVM what brings several disadvantages and cost more resources. So I really hope the Ubuntu Team can fix the problem in xen/pygrub.
