Btw., the reason I was looking at that code was that we observe zombie domains - ones in DOMDYING_dead state, perhaps having almost none of their memory freed (shadowed guests appear to be particularly bad). In one of the reports, an interesting extra fact was that this happened only for the first 100 guests - any subsequent ones got destroyed properly (obviously to get there this requires quite a bit of memory in the host). Has anyone else observed this? Does this ring any bells?
