Hi,
I have a domU guest that booted fine under Xen 4.4.1 with pvh=1 but now fails to boot with it under Xen 4.5.0. Removing pvh=1, i.e. booting it as traditional PV results in it booting fine.
The only odd thing is that I had to compile with debug=y on Config.mk to avoid a compiler warning that was causing compilation to fail outright. I will create another mail about that. DomU is Ubuntu 14.10 and Dom0 is 12.04.5
Here is the boot output when booting with pvh=1

there were some incompatible changes in xen 4.5 in regards to
PVH which were then updated in Linux 3.19 (or was it 3.18?)
I would recommend you rev up to the latest version of Linux.

Thanks. I was aware it was experimental, but just wanted offer the
chance to debug if the above behaviour was unexpected.

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. :)
Thanks for reading.
