The sysprep logic is only triggered once, the first time you start the
VM. So you will need to create it again, set the initialization data and
start it, basically repeat the steps that I suggested.

There were some bugs around this behaviour, some still not fixed in 3.5,
and it wasn't clear when the VM will use or not use sysprep, so we have
introduced a flag to explicitly force use of sysprep.

Please try to use this flag:

action = params.Action(use_sysprep=True)
vm.start(action)
