Nesting Hyper-V

[blackpaw]

Hi All, I'm trying to get Hyper-V working in a Windows 10 Preview guest - want to do this so that I can run the Windows Mobile Phone Simulator.

I've followed the guide here: http://pve.proxmox.com/wiki/Nested_Virtualization

And nesting seems to be enabled:

root@vng:~# cat /sys/module/kvm_intel/parameters/nested
Y

And have stared the VM up with " args: -enable-kvm" and the CPU set to "hosts"


But in the Windows guest, Hyper-V VM's fail to start.

Tthe Hyper-V Virtual Machine Bus Provider device is failing to start

The System Event Log has an entry: "Hypervisor launch failed; Either VMX not present or not enabled in BIOS"

Any thoughts?

Probably the requirement for SLAT tripping you up.

Ah, thanks. Tricky one that.
