Poweroff after windows installer loading

[K0SS4]

So my problem begins right after creating the vm. I do everything as in the tutorial(https://github.com/QaidVoid/Complete-Single-GPU-Passthrough#setup-guest-os) and when i click "Begin installation" windows starts loading(spinning windows circle) and then it shuts down.
I tried starting it with virsh and then viewing with virt-viewer but it's the same.

VM log file: https://pastebin.com/uc7HBHr8
/etc/libvirt/qemu.conf(default for arch): https://pastebin.com/8C4HShzq
win11.xml: https://pastebin.com/8D430qUq

My groups: libvirt-qemu libvirt video kvm input audio wheel k0ss4

It doesn't matter if it's windows 10 or 11. It behaves the same on both.

Thanks in advance :)

Couldn't find anything that might be causing the issue.

If your CPU has 16 threads only, try reducing the vCPU for VM.
Also, try setting the CPU topology manually.

Setting cpu topology manually didn't help. I set it to 1 socket, 4 cores, 2 threads and then 1 socket, 4 cores, 1 thread but it still crashes. However these lines in logs appear all the time:
qxl_send_events: spice-server bug: guest stopped, ignoring
2022-05-16 06:19:39.337+0000: shutting down, reason=crashed

But I don't know if it's spice-server causing the crash or if it simply cannot start because something else crashed before.

Thanks anyway

I solved it. It could not start because I gave it too much RAM. I don't have any swap partition/file so if firefox was launched on host then it crashed the vm bacuse i didn't have spare 15GB
