If the network to the bootstrap VM is slow, the extract-machine-os.service can time out (after 180s). If this happens, it will be restarted but services that depend on it (like ironic) will never be started even once it succeeds. systemd added support for Restart:on-failure for Type:oneshot services, but they still don't behave the same way as other types of services.

This can be simulated in dev-scripts by doing:

sudo tc qdisc add dev ostestbm root netem rate 33Mbit
