I mapped a Quadro K4000 into Ubuntu18.04 VM (QEMU-KVM), installed driver 450.80.02 Linux 64-bit.
After reboot, i was stuck in “cyclical login” state (after input password in login window, just got the login window again!)
I also tried CentOS 7 VM, the same problem.
And it works fine on Windows VM.
Please help me on this, thanks a lot!
