Hi List,
I am trying to run qemu with spice gl=on with the below command line
and getting errors.

qemu-system-x86_64 -cdrom ubuntu-18.04.2-desktop-amd64.iso -hda
u1.qcow2 -enable-kvm -m 1G -cpu host -smp 8 -machine vmport=off -boot
order=dc -device virtio-vga,virgl=on -spice
gl=on,unix,addr=/home/mjaggi/spice.sock,password=1,disable-ticketing
-soundhw hda -device virtio-serial -chardev
spicevmc,id=vdagent,debug=0,name=vdagent -device
virtserialport,chardev=vdagent,name=com.redhat.spice.0

qemu-system-x86_64: egl: EGL_MESA_image_dma_buf_export not supported
qemu-system-x86_64: Failed to initialize EGL render node for SPICE GL

Qemu configuration
./configure --enable-sdl --with-sdlabi=2.0 --enable-opengl
--enable-virglrenderer --enable-system --enable-modules
--target-list=x86_64-softmmu --enable-kvm  --disable-werror

...
OpenGL support    yes
OpenGL dmabufs    yes

As per configure script

#include <epoxy/egl.h>
#ifndef EGL_MESA_image_dma_buf_export
# error mesa/epoxy lacks support for dmabufs (mesa 10.6+)
#endif
int main(void) { return 0; }
EOF
  if compile_prog "" "" ; then
    opengl_dmabuf=yes
  fi
fi

So if OpenGL dmabufs   is yes, should I be getting
EGL_MESA_image_dma_buf_export not supported error ?
What I could be missing here
Need help/guidance.

-Thanks
Manish
