[Bug]: TestCLINetwork issue with vmnet when testing prune + run commands

[saehejkang]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

Capture the logs with command below

log stream --debug --info --predicate 'subsystem = "com.apple.NetworkSharing"'

Then the set of commands below similar to the prune test

#! /bin/bash -x

container system stop
container system start
container network rm in-use unused
container network create in-use
container network create unused
container run --name in-use-server --network in-use --rm -d -p 127.0.0.1:8000:8000 python:slim python3 -m http.server --bind 0.0.0.0 8000
container ls
container network rm unused
container stop in-use-server
container network rm in-use
container run --name default-server --rm -d -p 127.0.0.1:8000:8000 python:slim python3 -m http.server --bind 0.0.0.0 8000 
sleep 3
curl http://localhost:8000

Current behavior

The curl at the end fails, and the OS logs show that the container interface for default-server didn't get configured.

Expected behavior

TestCLINetwork pass and the default-server gets configured, when running the commands based on steps for reproduction

Thanks. This one is out of our hands for now. Since it impacts network deletion irrespective of pruning, let's get the network prune PR merged, but disabling the test that exposes this vmnet bug.
