Windows 10 1803 as guest with QEMU/KVM, BSOD under install

Okay, so when trying to launch a Windows 10 guest in KVM after updating to 1803 it just BSOD with the lines “System Thread exception not handled”. This happens when launching through KVM when Windows 10 1803 was installed on a drive, when upgrading Windows 10 1703 to 1803 and when plug in a live media to clean install(in a passed through usb controller). The windows guest ran fine with 1703. Anyone know anything? I am aware of the problems with the 600p drives. The xml file of the VM xmlVM.txt (4.5 KB) The conf file of QEMU xml.txt (28.4 KB) Manjaro 17.1 XFCE as host Linux kernel 4.14.39-1 Ryzen 1800x 32 GB RAM Corsair Dominator Platinum 3000MHz Gigabyte Aorus Gaming K7 Passthrough: Nvidia 1070 Host: Nvidia 970 Guest installed on a sata ssd Kingston Savage 480 GB or run from a live media usb Host is installed on a nvme ssd Samsung 960 EVO 480 GB As said by @magicthighs not using host-passthrough solves the BSOD, configurations that does not cause BSOD includes, but are not limited to, kvm64, qemu64 and core2duo. So I’m going with using qemu64 at the moment.

It’s main suggestions are not to use host-passthrough on the CPU and to use options kvm ignore_msrs=1 in modprobe.d
