3d acceleration Win7 Host, Win7 Guest

[krater]

Hello,

I try to activate the 3d Acceleration on Win7 Guests, but find no way to do.
I'm using VBox 6.1.27 r146933 (Qt5.6.2), switched to VBoxSVGA, activated the 3d acceleration, installed the Guest Extensions, but the 3d acceleration is deactivated in the Guest anyway.
On the Host the acceleration works.

Any Idea?

First, you are using an obsolete test build (6.1.27) of VirtualBox. Please replace it with the current release (6.1.30), and don't forget the Guest Additions too.

Then, we'll need a complete zipped log. Not an fragment of an unzipped log.
