VirtualBox 6.0 and Hyper-V

[mau67]

Hi,
I'm using r140284 on Windows10, I've enabled all Hyper-V flags in windows' settings and also the Windows Hypervisor Platform flag.
In BIOS the VT-x flag is enabled.
I'm running an Ubuntu20 VM, but no matter which setting I choose in the System|Acceleration|ParavirtualizationInterface menu, I always get the green turtle in the bottom right of the VM window.

Is this expected? How can I avoid it?

Thanks!

You're attacking the wrong part of the problem.

no matter which setting I choose in the System|Acceleration|ParavirtualizationInterface menu, I always get the green turtle

The 'Paravirtualization Interface' setting is for how the modern virtualization-aware OS communicates with the hypervisor, not the engine that runs the virtual machine. 'Paravirtualization Interface' should always stay on what Virtualbox first sets it to, Default being the safest. (An Ubuntu guest uses Default, which defaults to KVM.)

I've enabled all Hyper-V flags in windows' settings and also the Windows Hypervisor Platform flag....I always get the green turtle

Enabled Hyper-V causes the green turtle. If you want to disappear the green turtle, disable Hyper-V. See I have a 64bit host, but can't install 64bit guests.

@scottgus1 thanks a lot, things are much more clear now!
I disabled hypervisorlaunchtype using bcedit and now the green turtle disappeared.

Great! Glad you're up and running.
