Thanks. I was aware it was experimental, but just wanted offer the chance to debug if the above behaviour was unexpected. > > Sorry thought that it was not widely mentioned and it made your > day a bit sad.

I don't remember where I looked, tbh, although I would have read the release notes for 4.5 as a matter of course. I checked the PVH wiki entry and that merely refers to the "latest" of Xen and Linux. Perhaps that could be a bit more specific. My day wasn't made sad by this, but my day was a little sadder when I read (if I am reading it right) that AMD support for PVH (although slated for it) does not appear to have made it into 4.5. :)
