Way back I worked on a project to used virtualized routers inside labs for a bunch of use cases. The idea was to remove the need for building after building filled with equipment that just sat there idling 99% of the time. The biggest headache we had was to figure out when everything was up. There simply was no way to detect this programmatically, so the only way would have been to alter the code to give some kind of signal on the console like "System is up." similar to a linux box showing the login prompt. So I resorted to wait loops too. We ended up canceling the project.
