Hello,

I'm having big troubles with the latest version of VirtualBox to start my Linux guest machines with "3D Acceleration" enabled.

Setup:
- host OS - Windows 10 Pro
- GPU - Nvidia RTX 2070 MAX-Q
- VirtualBox 6.1.6

I have multiple Linux guest VMs which refuse to start when "3D Acceleration" is enabled.

Example:
- linux guest - Ubuntu 18.04 LTS
- guest additions installed and up to date
- last logged message from console - After the the above message the UI isn't loading at all, the machine just hangs.
Of course the moment I disable the "3D Acceleration" the guest OS is booting with no problem, but the UI keeps having bunch of issues while rendering components, example - I open Firefox and then start Terminal, the UI is freezing and sometimes performs user logout automatically.

I have resolved the issue by reverting to VirtualBox 6.0.14 and changing the Windows Hyper-V launch Type to "off" - .
Why I have to change the Hyper-V Launch Type ? - no idea, but without making the change and restarting my machine I cannot even open a session with VB to any guest VM.

It's getting even more interesting, because after changing the hyper-v launch type I can no longer use my Windows Docker.

I'd like to keep both my VMs and Docker running, so if anyone have encounter the problem I'd love some details and pointers ?

Yes, that will disable Docker. At present you cannot have both at once. Docker, like a Hyper-V guest, requires the hypervisor loaded. At the moment, most VirtualBox guests cannot run if the hypervisor is loaded. You will need to decide which you need most, or reconfigure your bootloader so that you have two boot modes, one with the hypervisor and one without.
