This morning the VM and host both still had networking. As I can't reproduce this, and as you have a working workaround (cheezy periodic ping) and a new LTS to try, I'm afraid I'm going to have to mark this as wontfix. I'd really like to get to the bottom of it, so if you happen to find new helpful info, please feel free to comment here.
