Hi,
I have working vm with passedthrough GTX 980 Ti. I run it with command
below.
QEMU_ALSA_DAC_BUFFER_SIZE=1881 QEMU_ALSA_DAC_PERIOD_SIZE=940
QEMU_AUDIO_DRV=alsa exec \
qemu-system-x86_64 \
-enable-kvm \
-smp cores=2,threads=2 \
-m 12G \
-cpu host,kvm=off \
-vga none \
-usb -usbdevice host:046d:c328 \
-nographic \
-usb -usbdevice host:046d:c069 \
-device vfio-pci,host=01:00.0,multifunction=on,romfile=/root/vbios.rom \
-device vfio-pci,host=01:00.1 \
-drive if=pflash,format=raw,readonly,file=/usr/share/OVMF/OVMF_CODE.fd \
-drive if=pflash,format=raw,file=/tmp/my_vars.fd \
-device virtio-scsi-pci,id=scsi \
-drive file=/home/iso/windows10_x64.iso,id=isocd,format=raw,if=none
-device scsi-cd,drive=isocd \
-drive file=/home/iso/virtio-win.iso,id=virtio,format=raw,if=none -device
ide-cd,bus=ide.1,drive=virtio \
-drive
file=/home/vm/firebird_ws/firebird_ws.img,id=disk,format=qcow2,if=none,cache=writeback
-device scsi-hd,drive=disk \
-net nic -net bridge,br=br0 \
Now I'm trying to run it under libvirt but I only getting TianoCore splash
screen on GPU output and windows boot's up and in VNC i see code 43 on gpu
card.
How to debug it and make it run?
