Reading Time: 3 minutes The latest Microsoft Windows Server 2016 Technical Preview 4 add an interesting new features in Hyper-V: Discrete Device Assignment. This feature implement a “device passthrough” for virtual machines running on Hyper-V: users can now take some of the PCI Express devices in their systems and pass them through directly to a guest VM.

Reading Time: 4 minutes As written in a previous post, the nested virtualization will be one of the future features of Microsoft Hyper-V. Actually Microsoft simple does not support nested virtualization in its Hyper-V product. Nothing wrong with it, but it’s a case where not supported means also that it simple does not work at all. And usually for production user cases it’s not necessary. But for testing and labs this features could be really useful, expecially in the client side of the hypervisor. In fact this feature has already been added to Windows 10 (starting with  the build 10565 of Windows Insider version).

Reading Time: 2 minutes Until now Microsoft simple does not support nested virtualization in its Hyper-V product. Nothing wrong with it, but it’s a case where not supported means also that it simple does not work at all. So the only way to test Hyper-V (or other hypervisor) in a lab with a single physical system (server or client) was using other hypervisors (VMware ESXi, Workstation, or also Paralles or others). Or using this trick (useful also with the new hardware requirement of the next Hyper-V) but with the big limit where the VMs cannot be powered on at […]
