SSH times out during VM start/provisioning (docker-rootful, user probe 1/1)

### Description

I can reproduce this fairly consistently, but not all the time. Symptoms are:

* `Waiting for the essential requirement 2 of 3` and `Waiting for the essential requirement 3 of 3:` takes a long time
* `Waiting for the optional requirement 1 of 1: "user probe 1/1"` takes a long time

See https://asciinema.org/a/cbVrF787KpHFq0Nx for full log.

With `--log-level debug` I'm seeing

```
