This might be somewhat old news for some readers but just want to share Microsoft has given indication they will provide nested virtualization capability on next release. This has been highlighted on the Windows Containers: What, Why and How session on Microsoft Build Conference.
This is one of the features most of the HYPER-V fans requesting from Microsoft (Including HYPER-V MVP’s as well). With this feature enabled we can enable HYPER-V role inside the Virtual machines. This would be really cool when we carry out demo labs.
