Extension Attribute to view VirtualBox VM OS Details

[ccarcamo]

I'm trying to create an extension attribute that will show me the OS details of any OS's running on VirtualBox. I realize that VirtualBox can host many different file types, so I'm wondering if anyone has had success trying to do this? I found an EA for Parallels OS details, but its strictly for Parallels. Thank you all in advance.

I'm not sure where I found this, but it might help with what you're looking for.

This worked perfectly, thank you @jhbush1973 !!

Do you know if we might be able to take it one step further and view what applications are installed on these VM's?

[c_archibald]

Is there an updated version of this?

[jtrant]

I'm looking for something similar, and found the Github page where it was originally posted:
https://github.com/killahquam/JAMF/blob/master/Virtual%20Machine%20Identifier/vm_os_checker.py

Doesn't look like it has been updated in quite a while.

FWIW: I grabbed the copy from Github.  Latest commit 9fed984 on May 2, 2015.

We have some Macs running VMware Fusion,  some with VirtualBox VMs, and some with Parallels.  (And some with more than one of those!)

The script is supposed to find all three, but it didn't find any of our Parallels installs.

It did find and report on the other two.  If your curious, here's what the output looks like for a Mac with VirtualBox and two VMs (one Win10, the other macOS Monterey):

VirtualBox Windows10_64 MacOS_64

Perhaps someone who knows Python and has Parallels can have a go at fixing it.
