[Qemu-discuss] qxl issues

[Divan Santana]

Hi all

I was successfully using qxl graphics with a guixsd host and arch guest
and spice enabled for sometime.

Then something changed, guesssing some update. Since then I can't get
qxl graphics to work anymore.

I start my arch guest like this:

--8<---------------cut here---------------start------------->8---
#!/bin/sh

NAME=$1
VMDIR=$HOME/images
qemu-system-x86_64 -name ${NAME} \
  -drive file=${VMDIR}/${NAME}.qcow2,format=qcow2,if=virtio \
  -netdev \
  bridge,br=br0,id=n1,helper=/run/setuid-programs/qemu-bridge-helper \
  -device virtio-net,netdev=n1,mac=52:54:00:4f:47:f2 \
  -enable-kvm \
  -cpu host -smp 3 \
  -m 4G \
  -soundhw hda \
  -vga qxl -spice port=5900,addr=127.0.0.1,disable-ticketing \
  -device virtio-serial-pci -device \
  virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 \
  -chardev spicevmc,id=spicechannel0,name=vdagent
--8<---------------cut here---------------end--------------->8---

The VM boots and logs into X and i3 and shortly after qemu dies with:

qxl_check_state: Assertion `!spice_display_running || 
SPICE_RING_IS_EMPTY(&ram->cmd_ring)' failed.

Anyone know how to debug this further to see where the issue is?

The other option for me would be to use virtio-vga graphics with spice.

How does one do that? (I don't have a working libvirt setup on my distro).
