Persisting and saving a UUID would cause DHCP to assign a static IP address. Not something Multipass supports.

I don't have a lot of knowledge about Apple's vmnet, so I just have some more general comments below.

Then bind_endpoint could be a method on VmnetBuffers, so here you'd just call:
host.bind_endpoint();
vm.bind_enpoint();

This PR adds supports for using additional network interfaces when using the
applevzbackend driver.This implementation of vmnet network interfaces was largely inspired by the following existing works:
Necessary modifications to integrate this code into Multipass is outlined at the top of
applevz_vmnet.mm, but all credit for unmodified code goes to the original author.See the vmnet documentation for more reading on vmnet API usage.
Once #4312 is merged into
mainand the interactions with theAvailabilityZoneManageris more finalized, this implementation can be easily extended to support shared network interfaces.MULTI-2259
