Change IP range in com.apple.vmnet.plist

We need the ability to customize the IP ranges used by the virtualization networking on macOS 12.x I see that the ranges are specified in /Library/Preferences/SystemConfiguration/com.apple.vmnet.plist

Editing this file and rebooting resulted in the file reverting to its previous state.

How can we change the network ranges and have them persist?

What service do I need to restart to pickup the changes?

Are you using vmnet via Virtualization framework? Or directly?

We are using VMware Fusion and it, in turn, is using the Virtualization Framework. I'm looking to see if there is a way to manipulate that config outside of what VMware provides. I do have a ticket open with them to see what they can provide.

Ideally, I could put together a script to update the config while we wait on fixes from VMware.

Thanks, Blake

Ah, OK. Unfortunately I can’t help you with this. DevForums is focused on code-level issues, hence my questions about frameworks. System configuration issues fall under the purview of Apple Support, and hence Apple Support Communities.
