Hi
Also just removing spice part makes it bootable:
-spice port=5900,addr=127.0.0.1,disable-ticketing=on

Title:
SPICE support broken with 6.0
Status in QEMU:
New
Bug description:
Using latest relase 6.0.0 while using Intel GVT-G DMA-BUF and SPICE
for usb redirection Qemu won't start:
qemu-system-x86_64: The console requires display DMABUF support.
However just patching ui/console.c:
if (flags & GRAPHIC_FLAGS_DMABUF &&
!displaychangelistener_has_dmabuf(dcl)) {
error_setg(errp, "The console requires display DMABUF support.");
return false;
}
to always return true for dmabuf part works just fine:
if (flags & GRAPHIC_FLAGS_DMABUF &&
!displaychangelistener_has_dmabuf(dcl)) {
error_setg(errp, "The console requires display DMABUF support.");
return true;
}
This behavior wasn't in qemu 5.x version.
To reproduce this bug need to use:
/usr/bin/qemu-system-x86_64 \
-machine q35 \
-enable-kvm \
-no-user-config \
-nodefaults \
-no-hpet \
-display gtk,gl=on \
-device pcie-root-port,port=0x0,chassis=1,id=pci.1,bus=pcie.0,multifunction=on,addr=0x1 \
-device vfio-pci,id=hostdev2,driver=vfio-pci-nohotplug,romfile=/sys/devices/pci0000:00/0000:00:02.0/gvt_firmware,sysfsdev=/sys/bus/mdev/devices/1ae40c36-b180-4af0-8fab-c27de21f597d,x-igd-opregion=on,ramfb=on,display=on,xres=1920,yres=1080,bus=pcie.0,multifunction=on,addr=0x2 \
-spice port=5900,addr=127.0.0.1,disable-ticketing=on

Did you actually get the dmabuf update displayed over spice? If not, then it is not a bug, it's a bug fix :) But I might be missing something.. I don't see how this could happen without egl-headless though.
