+# Running Hyper-V inside of a KVM/QEMU virtual machine
+
+This guide explains how to get Microsoft's Hyper-V hypervisor to successfully run inside a QEMU container running with KVM.
+
+## Common problems
+
+If you are using a virtualization framework that uses KVM (this includes Proxmox, oVirt, and plain qemu), and you have tried to run a Windows virtual machine with Hyper-V enabled, you will often find that your efforts are unsuccessful. Commonly experienced issues that this guide will help you resolve are:
+
+* Hyper-V just doesn't work. Trying to boot a VM throws errors.
+* Hyper-V seems to work, but networking stops working - your Hyper-V host VM cannot communicate over the network at all.
+* After enabling Hyper-V, your VM enters a boot loop - it crashes immediately upon trying to boot and throws you into Automatic Repair.
+
+The settings outlined in this guide will resolve these and possibly other issues that keep you from getting Hyper-V running inside KVM.
+
+## HOWTO
+
+### Requirements
+
+In order to be able able to do this at all, your host system's CPU must support SLAT (second-level address translation), which Intel calls EPT (enhanced page tables). On Intel, any processor in the Westmere series (Xeon L|E|X56xx series) and later should have the necessary support for EPT, with the exception of some low-end consumer CPUs in the Celeron and Pentium lines. For AMD, Phenom II or later chips should be supported.
+
+### Make sure nested KVM is enabled
+
+In order to run *any* hypervisor operating system you must ensure that nested virtualization is enabled in your host operating system. This will be similar on any Linux OS, including Proxmox and oVirt.
