I Done everything what tutorial says. I have amd gpu. (rx6700xt) grub: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 amd_iommu=on iommu=pt iommu=1 video=efifb:off disable_idle_d3=1" I have iommu enabled in my bios. The /var/log/libvirt/qemu/win10.log is empty. The only thing I could done wrong is not installing the Virtio drivers in windows. I could break it by remaking the vm again (like i deleted the vm machine and make it again. but it was after the black screen issue ) btw how can I make the vm to not taking thole monitor? Would be nice to just have it in one of my workspaces.

Might be an Issue with your vBios. Check if you are using correct one.

Are u sure you understand how single gpu passthrough works?

so it's like taking over the wole gpu ? I thought it's just split the gpu or something, just like cpu. I'm new to Linux so sorry for any stupidity of mine.
