Are you using an Intel or AMD processor? Looks like some Bios config are specific to Intel.
I gave up. I have to run a VirtualBox VM for my work which means I have to have HyperV disabled, which means the Android emulators don’t work... also tried the arm images but no cigar.
I’m running a Ryzen CPU and I feel like that’s half the battle.
You could technically migrate your VirtualBox VMs to Hyper-V.
