QEMU and Windows 10 r17763

Hi,

I have been having severe issues with running an updated Windows 10 in QEMU/KVM. I have been stably running for at least 1.5 years, and this has stopped working once I updated Windows 10 recently. I was also not able to make a freshly installed Windows 10 system work anymore, also after I have installed the latest virtio drivers on Windows. I had to switch to VirtualBox, where everything runs really nicely.
In QEMU I get BSODs with 'KMODE EXCEPTION NOT HANDLED'. Googling shows this might be related to driver issues. Since the only drivers that I installed are the virtio drivers virtstor, qxldod, kvmnet and the serial thing (forgot what it is called), I have my suspicion that the newest Windows update somehow kills the compatibility with those drivers.

Anyone experiencing something similar? Or have found some references I can read?

Thanks in advance! Here is how I run this:

https://bbs.archlinux.org/viewtopic.php?id=247692 suggests it may be kernel related.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Thank you - I missed that thread. Bummer.
