[vbox-dev] Enabling 3D acceleration with VBoxOGL and VBoxECL

[Sérgio Basto]

Hi Larry, 

where are your fixes
https://build.opensuse.org/package/show/Virtualization/virtualbox ? 

Unfortunately I don't have much time to look at , but the primary
problem IMO is install vboxvideo_drv.so [1] 
since 5.0.18 we shouldn't install it in modern X11 with EGL (I think) 

Another thing that I like understand is sonames , I use [2] 
you now have another recent fix [4] in revision 311 (Remove file
"vbox_prevent_wrong_SONAME.patch" ) which was like my patch ...

Not he solution is : 
+# Do not provide libGL.so symbols - they are owned by Mesa already and
this could potentially confuse rpm/zypp
+%global __provides_exclude ^libE?GL.so.1.*$

I have 3D working with my patch  

Another ideas: 
- I need patches for kernel 4.11-rc0-git9 
- as we downstreams in distros also provides guest packages,  maybe can
be established , when install opensuse in a vm , instead run a script
we may install rpm packages virtualbox-guest [3] 
- when we got a new upstream release ? I expect it to see and to test
gcc7 and test last patches for kernel 4.10 and new patches for kernel
4.11 ... 

Sorry to land here without parachute
Best regards and thanks,
