Can't create 64 bit virtual machines after hyper-v was enabled

[radix]

Hello,

After I've enabled Hyper-v in Windows 8 Enterprise 64 bit via "Control Panel > Programs > Turn Windows Features on or off", I can't create 64 bit virtual machines using VirtualBox. Disabling Hyper-v fixed the problem. CPU is Intel Core I7-3770k and virtualization is enabled in bios. Anyone knows a workaround to have Hyper-v and 64 bit virtualization ?

Thanks.

Maybe you can be the first to figure it out! Apparently...

Yes, it does conflict with each other. You will get strange errors when both want to use hardware-V, something that's enabled by default in VB. And since Hyper-V runs as a service, it will lock it so VB cannot use it.

It seems to be a foregone conclusion that VirtualBox does not work when Hyper-V is enabled.

The common "fix" I can find is to diable Hyper-V... which isn't really a fix at all if you ask me.

But i wonder why you need to run both?

maybe he does WP8 development which requires Hyper-V.

Disabling is the "fix". Thanks!
