The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.

Thoughts?

Sorry, not quite following your comment - but it's likely me :-(.
I assume you mean QEMU - but build against what upstream library? I ask
because for QEMU to build, only the three header files from Windows are
copied over, and then it calls / uses the dll's (libraries) in Windows
itself ... right?
I don't think QEMU can do anything to fix this - you need to build
against a new library.

Hi,
I tried backing up ... nothing but startup and UEFI (i.e. no OS, just
get to the EFI Shell). Can't even get there ... does that make sense?
Thanks!

As far as I can tell QEMU just hands this off to the whpx emulation sub-
system:

Basically what is happening is the guest has tried to access I/O space
and trapped back to QEMU whi

Sorry for the typo. I should have mentioned that this issue is WHPX
related. I have created an issue in WHPX Github page about it.

Which OS do you try with qemu? IIRC Windows 10 should work well with
WHPX. Also,this issue is qemu depended that they don't handle specific
MMIO instruction/exit.

FYI, I was curious if this was a Ryzen issue or not (which I am running), so I
tried another machine - here are the two combos I tried,
1) Ryzen 5 2600X, Windows 19041.172
2) Core i5-6600K, Windows 18363.720
Same issue on both.
Thanks!
