The other day I just happened to try to install Windows 2003 on
xen-unstable tip.  After booting the CD and copying the files, the
whole thing stops at "Setup is starting Windows".

The VM is in the "blocked" state; which means it has called HLT and is
waiting for interrupts; but no interrupts are delivered, so everything
just stops.

Windows XP, strangely enough, installs just fine.

I have duplicated this with both qemu-upstream and qemu-traditional;
and also on both AMD and Intel.

I was wondering:
1. if any of you had an idea what changeset might be involved
Any of the RTC emulation changes since 4.2 would be possible
candidates, with mine much more likely than Tim's (since his mainly
fix issues mine introduced).
If you've got a git hash tag for your first change, I can do a quick
test to see if that's it.
The first of these commits is 2fe82ac11fd078485388fe7c5e8bc3b6ac9185b0.
Here are the results of my bisect:

620d5dad54008e40798c4a0c4322aef274c36fa3 is the first bad commit
commit 620d5dad54008e40798c4a0c4322aef274c36fa3

      x86/HVM: assorted RTC emulation adjustments
So time to really consider a (partial) revert then, as obviously Tim's
attempt to fix this without reverting weren't successful (I take it
that you were at the tip of -unstable before starting the bisection).

Yes, the tip of -unstable (as of what, 2 days ago?) didn't work.
