In general this works well, however if the laptop has *ever* suspended since its last boot, then the windows guest reports an error 43 on the card and I get no output on the monitor that it is connected to. This is really weird to me since it works fine if I boot the latop from power-off, and hotplug the card. It's only if the laptop has ever suspended since it's last boot that I see this issue. Even if it was suspended before the card was ever hotplugged. - -In other words: -laptop off -> boot -> hotplug GPU : works great -laptop off -> boot -> do stuff (GPU *NOT* connected) -> sleep -> resume -> hotplug GPU: problem -laptop off -> boot -> hotplug GPU -> unplug GPU -> hotplug GPU : works great -laptop off -> boot -> hotplug GPU -> unplug GPU -> sleep -> resume -> hotplug GPU: problem - -Weird stuff... - -I'm honestly not sure that vfio-pci/qemu is to blame here since there are so many moving parts, but im not really sure where else to report this to - -What I have tried is using the sysfs interface to remove/rescan/poweroff/etc the PCI devices in questions (graphics card and it's HDMI audio) and this also does help. - -QEMU version: 2.6.1 - -Please let me know what other information I can provide \ No newline at end of file |
