After the upgrade HVM domUs appear to no longer work - regardless

domUs, however, work just fine as before on both dom0 kernels.
xl dmesg shows the following information after the first crashed HVM

Other than RIP looking odd for a guest still in non-paged protected
mode I can't seem to spot anything wrong with guest state.
odd? That will be the source of the failure.
Out of long mode, the upper 32bit of %rip should all be zero, and it
should not be possible to set any of them.
I suspect that the guest has exited for emulation, and there has been a
bad update to %rip. The alternative (which I hope is not the case) is
that there is a hardware errata which allows the guest to accidentally
get it self into this condition.
Are you able to rerun with a debug build of the hypervisor?
[snip]
Another question is whether prior to enabling the debug USE flag it
might make sense to re-compile with gcc-4.8.5 (please see my previous
list reply) to rule out any compiler related issues. Jan, Andrew -
what are your thoughts?
First of all, check whether the compiler makes a difference on 4.5.2
Hi Andrew,
I changed the compiler and there was no change to the better:
Unfortunately the HVM domU is still crashing with a similar error
message as soon as it is being started.
If both compiles result in a guest crashing in that manner, test a debug
Xen to see if any assertions/errors are encountered just before the
guest crashes.
As the compiler did not make any difference, I enabled the debug USE
flag, re-compiled (using gcc-4.9.3), and rebooted using a serial console
to capture output. Unfortunately I did not get very far and things
become even stranger: This time the system did not even finnish the boot
process, but rather hard-stopped pretty early with a message reading
"Panic on CPU 3: DOUBLE FAULT -- system shutdown". The captured logfile
is attached as "serial log.txt".
As this happened immediately after the CPU microcode update, I thought
there might be a connection and disabled the microcode update. After the
next reboot it seemed as if the boot process got a bit further as
evidenced by a few more lines in the log file (those between lines 136
and 197 in the second log file named "serial log no ucode.txt"), but in
the end it finnished off with an identical error message (only the CPU #
was different this time, but that number seems to change between boots
anyways).
I hope that makes some sense to you.
Many thanks for your support and best regards Atom2
