MacOS 15.1 B2 update not triggering within a VM.

I have MacOS 15.1 B1 running in a UTM Virtual Machine, and 15.1 B2 running as its host OS.

14" M3 MBP.

The VM does not automatically offer a software update to 15.1 Beta 2.

I've already installed the Device Support for MacOS 15 Beta, but I don't know what else I need to activate. Do I have to run a shell script or app, etc?

Any ideas?

Thanks in advance.
