As you probably know, on the Build conference was announced the Developer Previews of Windows 8 and Windows Server 8.
Because of the numerous new features in Hyper-V 3.0 I want to check them personally. Because I do not have two spare boxes on which to install them, virtualization comes in play.
Before Hyper-V role is added to the server, there is configuration to be made on the Virtual Machine:
The best description of the process that I find is in this article:
Nesting Hyper-V with VMware Workstation 8 and ESXi 5
In the Processors configuration Virtualize Intel VT-x/EPT must be checked,
And one line must be added to the configuration file vmx:
hypervisor.cpuid.v0 = “FALSE”
That’s it, now you can add Hyper-V role and play with it.
