[Spice-devel] Spice OpenGL does not work

[王杰东]

Ok , i will use a desktop processor to try again .
But do the errors : "virtio 3d acceleration is not  supported" and "egl: no drm render node available , Failed to initializa  EGL render node for SPICE GL" result from hardware devices only or some error configurations ?

The idea of Virgl is to use the host card GPU 3D capabilities to accelerate/provide 3D rendering.


Your card is mainly a 2D VGA card, really useful for remote system administration but quite useless for Virgl.
Desktop processors integrate an Intel GPU which is enough for Virgl.
About ATI/NVIDIA support I'm not sure the support level. dma buffer support is required but seems
missing in NVIDIA cards. Try asking to Qemu mailing list.

I use SuperMicro Server to test , it have a Xeon E5-2620 CPU and a ASPEED Video AST2400 , but no discrete GPU . Should i add a ATI/NVIDIA ?
and the outputs are:


 - ls -l /dev/dri
crw-rw-rw-+ 1 root video 226,  0 Nov  3 08:32 card0
crw-rw-rw-  1 root video 226, 64 Nov  3 08:32 controlD64



-eglinfo
Using default X11 display

I followed the section "GL acceleration (virgl)" of spice-user-manual.html to configure my host , but it always failed , 
i updated my environment like this : qemu 2.10 , libvirt 3.6 , spice-server 0.13.90 , spice-gtk 0.33, spice-protocol 0.12.12 , virglrenderer 0.6.0 , but it still did not work .
the errors i cannot resolve include "virtio 3d acceleration is not supported" and "egl: no drm render node available , Failed to initializa EGL render node for SPICE GL" .
if you have some advice or somthing that i ingore to use spice opengl, please help me , thanks !
Would be useful to understand which GPU you have.

Would be useful outputs from:

- ls -l /dev/dri

- lspci -v

- eglinfo

(last in egl-utils package)
