I passed a nvidia graphic card to a virtual machine with KVM. I seted '-vga none' because vga in qemu will conflict with the gpu that I passed to VM in windows 7. I will get code 12 with graphic card in Device Manager when I set '-vga cirrus' or '-vga qxl'. I could not connect to VM by spice because I had set '-vga none'.
The '-vga cirrus' will not conflict with the gpu in Windows 10, but spice will connect to vga instead of the graphic card that I passed to VM. How can I connet to the graphic card and controll the vm by spice? Here my qemu command: /root/qemu25/qemu/x86_64-softmmu/qemu-system-x86_64 \ -name i-gputest \ -machine pc \ -m 2048 \ -boot strict=on \ -smp 2,sockets=1,cores=2,threads=1 \ -hda /root/gputest/windows7.raw \ -k en-us \ -drive if=pflash,format=raw,readonly,file=/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd \ -drive if=pflash,format=raw,file=/root/gputest/OVMF_VARS-pure-efi.fd \ -device vfio-pci,host=44:00.0,multifunction=on,x-vga=on \ -device vfio-pci,host=44:00.1 \ -spice port=5944,disable-ticketing \ -vga none Regards, John
