Ok i think it is working correctly now, what i did is this:
1) start Xvfb instances:
Xvfb :1 -screen 0 1024x768x24 -fbdir vfb_test/fbdir1 &
Xvfb :2 -screen 0 1024x768x24 -fbdir vfb_test/fbdir2 &
...
2) start vglclients
/opt/VirtualGL/bin/vglclient -display localhost:1.0 -port 4242 -detach
/opt/VirtualGL/bin/vglclient -display localhost:2.0 -port 4243 -detach
3) start applications to be tested
/opt/VirtualGL/bin/vglrun -cl localhost:4242 +v -c rgb -sp -fps 5.0 --
../Downloads/VirtualGL-2.3.2/bin/glxspheres
/opt/VirtualGL/bin/vglrun -cl localhost:4243 +v -c rgb -sp -fps 5.0 --
../Downloads/VirtualGL-2.3.2/bin/glxgears
which works great, as Xvfb renders each display successfully
only thing that is worrying me is a message that the rendering context
is indirect after i start glxspheres:
$ /opt/VirtualGL/bin/vglrun -cl localhost:4242 +v -c rgb -sp -fps 5.0
-- ../Downloads/VirtualGL-2.3.2/bin/glxspheres

any idea why i'm getting this message? does it mean that is not doing
GPU rendering?
thanks for your help so far!
