Abstract: Techniques for managing configuration of virtual switches in a virtual machine network are disclosed. In an embodiment, a virtual machine network that includes virtual switches is configured to revert back to a saved network configuration if a configuration change causes the connection between the VM management system and a managed node to be lost. For example, before any configuration changes are made, the active configuration is saved. If the new configuration supports a working connection between the managed node and the VM management system, then the saved configuration is no longer needed and can be flushed from memory. If, however, the new configuration causes the managed node to be disconnected from the VM management system, then the system reverts back to the saved configuration that was previously known to work. The saved configuration is used to reestablish the connection so that the network continues to function.

Abstract: Techniques for managing the configuration of managed nodes in a virtual machine network are disclosed. In an embodiment, managing the configuration of a managed node involves creating a clone of a virtual port on the managed node and using the cloned virtual port as an alternative communication channel between the managed node and a virtual machine management system to modify the virtual port. This technique can be used to restore connectivity to a managed node, such as a virtual switch, when connectivity is lost due to a misconfigured virtual port.
