After launching qemu I have qemu display from intel gpu(gvt-g), terminal
output of launched script. After that launching in terminal separate
instance remote-viewer for spice to passthru usb devices - spice dislay
is blank, that was also in 5.x versions, but just now to get spice
running I need to patch check to always return true. As I understood I
have egl-headless window as there is fully aclerated guest video output:
Full comand that I am running is as follow:

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 \
