Customizing Network Configuration of Virtual Machines Using Subnet Mapping Rules

摘要

Techniques disclosed herein provide disaster recovery IP customization based on rules associated with virtual networks that virtual machines (VMs) are connected to. In one embodiment, the rules are applied to each recovered VM to dynamically derive new TCP/IP settings at a recovery site based on TCP/IP settings used at a protected site and the virtual networks that the VMs is connected to at the protected and recovery sites. In particular, the rules may be defined in IP mapper objects associated with mappings between protected site networks and recovery site networks. During disaster recovery, the protected-site-to-recovery-site network mapping for a vNIC of a recovered VM is determined and rules that are defined in the IP mapper object associated with such a network mapping are evaluated to generate new TCP/IP settings.

主权项

1. A method of configuring network settings of a virtual machine (VM) running at a first location and recovered or migrated to a second location, comprising:
identifying, based on virtual networks to which the VM is connected at the first and the second locations, a rule for customizing a network configuration for the VM at the second location, the rule providing a mapping between a network configuration of the VM at the first location and the network configuration of the VM at the second location; programmatically applying the rule to determine the network configuration of the VM at the second location based on the network configuration of the VM at the first location; and configuring network settings of the VM recovered or migrated to the second location using the determined network configuration.
