Windows Failover Cluster with Hyper-V nested

Occasional Contributor

Is it okay to build a Windows Failover Cluster with Hyper-V nested?

Please let me know if there are restrictions on Windows.

You can use nested virtualization on a Hyper-V failover cluster.

You need the following system requirements on your physical hosts:

  • Windows Server 2016 or higher
  • Intel Processor with VT-x and EPT

You also need to take special care for virtual machine networking. You have to enable MAC Address Spoofing for your virtual Hyper-V hosts. Also you lose any online memory resizing inside a VM with enabled nested virtualization. Meaning you can't use dynamic memory or hot-add/remove memory with nested virtualization.

Thank you for answering.

Does it mean that it can be built with some restrictions?
Is it not recommended for MS?
