Bug description:
Problem:
Passthrough of a PCI-E Nvidia GTX 970 GFX card to a Windows 10 guest from a
Debian Stretch host fails after recent changes to kvm in QEMU master/trunk.
Before this recent commit, everything worked as expected.
QEMU Version:
Master/trunk pulled from github 4/10/17 ( git reflog: d147f7e815
address@hidden )
Host:
Debian Stretch kernel SMP Debian 4.9.30-2+deb9u5 (2017-09-19) x86_64 GNU/Linux
Guest:
Windows 10 Professional
Issue is with this commit:
https://github.com/qemu/qemu/commit/f357f564be0bd45245b3ccfbbe20ace08fe83ca8
