Windows 10: HYPER-V and VMWare / VBOX concurrently

Hi Windows Gurus I'm at a bit of a loss to understand why Windows can't run VMWare and HYPER-V concurrently while VBOX seems to get indeterminate results -- some say it works others say it just hangs. I've messed around quite a lot with the QEMU/KVM equivalent Hypervisor and it has absolutely NO problem running Guests on VBOX, VMware, and HYPER-V (2nd level VM --very slow though !!) all concurrently as well as VM's on its own platform. OK if you do this you can only passthru hardware to specific VM's - but the normal paravirtualisation works so VM's will run concurrently. Linux kernel --5.4.13 Here's two W10 VMs running on KVM/QEMU and VMWare concurrently - no problems at all. So this must surely be a Windows issue rather than a VMware or Oracle (VBOX) problem -- I know VMWare is working to get this resolved in a new release -- that means though yet more expense !!! to something that already works on another platform. I wish Windows developers would concentrate more on these sorts of issues rather than messing about worrying what new icons look like and things like that. Cheers jimbo

Hi Windows Gurus

HYPER-V and VMWare / VBOX concurrently

The reason VBox works with Hyper-V role enabled is because they changed their program to make use of the Windows Hypervisor Platform API released in 1809. When VT-x is unavailable VBox will try to fallback to use the Hyper-V framework (a.k.a. NEM or Native Execution Manager). See VirtualBox 6.0 and Hyper-V

Android Emulator has also been updated to use this but apparently VMWare hasn't yet although according to this blog they are developing it.

Comparing Hyper-V with KVM is difficult as they work differently. Whether it is a type 1 or type 2 (or even if such a distinction makes sense any more) is debatable. See Is KVM a type 1 or type 2 hypervisor?

Hi there
@lx07

I see you use a Mac -- does Parallels work on that system OK or is it rubbish -- don't see too much about that.

BTW KVM can re-start VM's etc from re-boot of HOST







(Thanks for the plus BTW)
