I think one of those gtk patches broke mouse/keyboard grab for my
Windows 8 vfio/vga-passthrough setup in 2.1.0 and I was instructed on
IRC to report that here.
With 2.0.0 I got a black qemu window with "This VM has no graphic
display device", which I could click on to get a mouse grab.
With 2.1.0 I just get the qemu monitor window.
If I press Ctrl-Alt-g or use the corresponding menu entry, the gtk
window grabs the input devices and the titlebar changes to "press
Ctrl-Alt-g to release grab", but none of the input reaches the vm.
I tried all of {gtk3, sdl} x {usb-mouse, usb-tablet}:
With gtk3, none worked.
With sdl usb-tablet worked, but I haven't figured out how to do an
actual mouse grab. (maybe related to me passing "-vga none"?)
If I drop the "-vga none" I can get a mouse-grab, but the passed-through
gpu won't work, so this is no option for me.
If needed I can produce some logs with both 2.0 and 2.1, but I don't
know what options I should pass to qemu to make those useful.
Here is how I start qemu:
qemu-system-x86_64
-enable-kvm -M q35 -cpu host,hv-time,kvm=off -vga none
-m 8192 -smp 2,sockets=1,cores=2,threads=1
-bios /usr/share/qemu/bios.bin
