code looks good and functionally sane but this needs extensive testing.
Especially when master fails the dns functionality needs to be still available,
i.e. be started on the new master. @dsclose did you test this?

> Components: Virtual Router
> Affects Versions: 4.3.0
> Environment: KVM
> Reporter: Magnus Bengtsson
>
> When using a network offering with redundant routers the default setting of
> EnableServiceMonitoring enables monit on the routers.
> "network.router.EnableServiceMonitoring service monitoring in router
> enable/disable option, default true false"
> This causes monit to run dnsmasq on both the Master and Backup router. When
> the backup router assigns dhcp to clients, password and userdata retrieval
> from that node fails since the services are not running on the backup router.
