How to Get (Windows Server Host Name or IP) Hyper-V VM Host Name or IP Details from Debian-Based Hyper-V VM

Question

Hi everyone,

I'm currently running a Debian-based VM on a Windows Server 2022 Hyper-V host. I need to execute some PowerShell commands on the Windows Server from my Debian VM. Typically, I would do something like this:

ssh user@windows-server_ip 'powershell -Command "storcli.exe /c0 /vall show"'

Example :

However, I want to automate this process and avoid specifying the windows-server_ip or hostname every time. Is there a way to dynamically retrieve the Hyper-V host's hostname or IP from the Debian-based VM?

Answer 1

I successfully retrieved the Hyper-V VM Host Name from a Debian-based Hyper-V VM.

Since Debian 12 does not hv_kvp_daemon preinstalled, I installed it along with the hyperv package to read the necessary files:

root@DEB-HYPV-Debian12:~# apt-get install hyperv-daemons 

root@DEB-HYPV-Debian12:~# pip install hyperkv

Finally, I ran hyperkv and obtained the following output:
