I uploaded win10.log and libvirtd.log, I wonder if it will help?

add log libvirtd.log win10.log

I have the same issue, how do you solve that?

[Jotalz]

no...

[caoshuai619]

no...

It seems this is a kernel issue , found in https://www.reddit.com/r/VFIO/comments/wp85ve/linux_519_kernel_single_gpu_passthough_black/?sort=confidence, and has not been fixed yet. So i decided to change the tear-down script to restart the pc.

Yes, I changed the last command to reboot =)
