The very first domain I create gets ID=2:

xm create win2008.cfg
Using config file "./win2008.cfg".
Started domain win2008 (id=2)

Should have id 1.

I've also noticed that if i shutdown the domain cleanly (ie from
inside windows) then I can start it again without any problems, but if
i have to use xm destroy then when I next try to start the domain the
xm process hangs, if I ctrl+c the xm process the domain is listed and
paused, I can unpause it and it seems to work ok.

xenstore-ls shows that some of the domain devices etc are not removed,
should they be when it is destroyed?
