I don't know of any other way to address this either, except perhaps switch to XenAPI so we can update individual fields, instead of having the re-define the whole VM. > > > Also, why isn't this represented in the XML? > > > > Bear in mind there's 2 impls of this.

We didn't consider autostart to be configuring the guest VM itself, but rather be a policy/tunable setting relating to control of the VM. And it was treated this way in XenD too...until it was added to the SEXPR.
