Systems for bring-up of virtual machines in disaster recovery scenarios where the network configuration differs between the failed system and the recovery system. A method commences upon identifying a disaster recovery plan for restarting a set of virtual machines on a second system (e.g., a recovery system). A disaster event is detected, which event causes initiation of aspects of the disaster recovery plan, including restarting the set of virtual machines that were running on the first system. Other aspects of the disaster recovery plan include determining a set of network configuration directives pertaining to the second system, and providing access to the network configuration directives by any of the restarted virtual machines. During disaster recovery bring-up, at least some of the virtual machines that are restarted on the second system use the network configuration of the recovery system.
