I created a PR for this (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200210) and will look into it. Thanks Thanks in advance for any ideas, tap will work, though, I suspect you're using vtnet to retain a config'd IP address when the guest exits ?? I don't have a specific use case. I was trying something (*) and I got this panic and I reported it;) *: I was testing a big STP experiment with VIMAGE and I wanted to connect the host to the experiment and I got this panic. After that I tried to narrow down the panic's trigger, so I removed VIMAGE and tried to connect vtnet to a bridge.
