GIM (Guest Interface Manager) in VirtualBox

[bolen_vmm]

Hi guys,

I have installed win7 and win8 as a guest on vbox.
I have tried to use GIM (Guest Interface Manager). I wanted use hyper-v compatibility interface in vbox from my win7/win8 guest.
But all time when i try to write to hyper-v hypercall interface i catch exception.

Should I enable somehow GIM (Guest Interface Manager)? Is this interface still support? How can I use it?

Thank for help.

Better ask on VBox devel mailing list than user forum.
