Hi all,

Qemu 2.11 works as expected, with qemu 2.12 that got stable recently I get a blank and dark display on a guest using virgl.

Here is the guest qemu init script if that matters:

Code:

#!/bin/sh
# ip addr 10.253.0.2, tap0, mac 01, monitor 2001
export QEMU_AUDIO_DRV=pa
exec qemu-system-x86_64 \
        -enable-kvm \
        -machine q35 \
        -device intel-iommu \
        -usb \
        -cpu host \
        -smp cores=2,threads=2 \
        -drive file=/var/qemu/arch/ovmfcode.flash,format=raw,readonly,if=pflash,id=drive0 \
        -drive file=/var/qemu/arch/ovmfvars.flash,format=raw,if=pflash,id=drive1 \
        -object iothread,id=t0 \
        -device virtio-scsi-pci,iothread=t0 \
        -device scsi-hd,drive=root \

        -net nic,macaddr=52:54:00:F0:0D:01,netdev=nic-0,model=virtio \
        -m 4G \
        -vga virtio \
        -display gtk,gl=on \
        -soundhw hda \
        -spice unix,addr=/var/run/user/1000/arch.socket,disable-ticketing \
        -device virtio-serial-pci \
        -device virtserialport,chardev=spicechannel1,name=com.redhat.spice.0 \
        -chardev spicevmc,id=spicechannel1,name=vdagent \
        -device qemu-xhci,id=xhci0 \
        -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,debug=0 \
        -chardev spicevmc,name=usbredir,id=usbredirchardev1 \
        -name "Arch" \
        -monitor telnet:127.0.0.1:2001,server,nowait \
        -daemonize \
        $@


here is my emerge --info

For sure, it seems to be related to the graphics driver. I have a GTX1050Ti, and using the stable proprietary drivers. Interestingly enough, I get the display as expected with nouveau, but nouveau is unsuable with a 1050Ti. I tried also withe the test mesa 18.1.2, but no luck.

Any clue welcome.

Cheers
