Find the Hostname of a Hyper-V VM

If you are running a virtual machine (VM) on Hyper-V, sometimes you want to know on which Hyper-V host this VM is running. If you don’t have access to the Hyper-V host, you need to find that information from within the virtual machines operating system. Luckily, the hostname of the physical Hyper-V server the virtual machine is running on can be found in the virtual machines registry.

You can find that information under the following registry key:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters

You will get some additional information about the Hyper-V host as well was the Physical Hyper-V Hostname of the VM.

You could also run the following PowerShell command to get the Hyper-V hostname inside the VM:

Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters"  | Select-Object HostName

Since we run a version of Hyper-V in our Microsoft Azure datacenters, this also works with Azure VMs.
