Black screen and kicked back to login screen after a few seconds

[hibert2323]

I followed your guide successfully, but when I start my win10 vm I'm back at my sddm login screen after 4 seconds.
I am using a 1070 GTX for the passthrough on my fresh arch install. (KDE / sddm) Can you help me ?

Can you try renaming the vm to something other than "win10" and remove the GPU PCI devices? When you start it, it will likely spit out an error message that I can help decode.

thanks for your replay. I followed your instructions, vm renamed to "test10", 2 GPU PCI devices removed. now it seems to start normally. I noticed that my USB controller is still configured. as a result, my keyboard is reconnecting to the vm and becomes unusable for the host. So i remove the USB conntroler as well. And now i have a headless vm running in the background, no errors. Do you need logs again ?

I got it working now. In my case, the patched vbios file was located in /var/lib/libvirt/vbios/Rom.rom.
I mv it to /usr/share/vgabios/Rom.rom and updated the path in my GPU PCI device's .XML

Thank you anyway for your time and your guide ;)
