This question is not related to How to select paravirtualization interface in virtual box
In Virtualbox 5.1.x I saw various paravirtualization options in the "Acceleration" tab of my VM settings.
I remembered Windows 10 did not install Hyper-V, so I went to "Add remove program features" (or similar) in the Control Panel and I checked the box for Hyper-V.
After two reboots I went into VBox and the Acceleration tab is completely disabled.
Is it an expected behavior? would Hyper-V work also without the Hyper-V components from Microsoft?
