I installed a Win8 Dev Preview x64 guest on a Win7 Pro x64 host with no problems.
I did not try to install Guest Additions, since that already has been reported not to work yet.
I also updated to the latest version and since testing Windows 8x64 Dev I installed the new additions (4.1.4).No problems so far.At first a compatibility prompt will appear just accept and installation will complete.Now mouse can move freely between host and guest screen.
Thanks for letting me know the GA does install!
My mouse moved freely between my host (Win7 Pro x64) and guest OS (Win8 Preview Dev x64) with no Guest Additions installed.
I was able to install the x64 version of v4.1.4 Guest Additions with no need to select Compatibility Mode.
VirtualBox virtual network shares work. (the shared folders feature)
Copy-and-Paste between guest and host works (I used it for the error message below; although I don't know if the Additions were needed for it).
However, the graphics driver cannot be installed.
Win8 Device Manager --> Display Adapters --> VirtualBox Graphics Adapter --> Properties --> General (tab)

Windows cannot initialize the device driver for this hardware. (Code 37)

That last line explains why the graphics driver cannot be initialized.
Windows 8 x64 requires that all drivers be digitally signed.
Hopefully this can be fixed in the next VirtualBox update.
