Start point :
HOST : Opensuse leap 42.3 running Opensuse Virtualbox 5.1.22 ( opensuse naming ) from kernel 4.4.75-1-default to 4.4.87-25-default ( oracle virtualbox 5.1.22 does not install on leap 42.3 . See oracle bug ticket bug #16966 )
Guest : Windows 10
Every thing running normally.
First step :
Install linux opensuse leap 42.3 as guests with success.
But cannot install guest addition --> give black screen or screen without menu system.
Shared folders worked.
Second step
Due to information from Opensuse saying :
I tried Opensuse Virtualbox 5.2-5.2.0_118431 with no success ( same error as with 5.1.22 )VirtualBox-5.1-5.1.28 is available from the Oracle site for download, and it does work now with openSUSE LEAP-42.3. I tested it earlier today.
Third step
Remove Oracle virtualbox 5.2
Reinstall Oracle virtualbox 5.1.22 + Guest addition 5.1.22
win 10 is OK
Linux VM give black screen or screen without menu system (seems to have X86 problem).
Startx from init 3 show X86 problem
Forth step
Remove Oracle virtualbox 5.1.22
Reinstall Opensuse Virtualbox 5.1.22 + Oracle Guest addition 5.1.22
win 10 is OK
Linux VM give black screen or screen without menu system.
Startx from init 3 show X86 problem
After googleing, I remove 3D acceleration.
That works.
So now what to do to have a normal config for the linux guest.
What should I do to give you more technical info.
