SYSTEM AND METHOD FOR MANAGING CONFIGURATION OF VIRTUAL SWITCHES IN A VIRTUAL MACHINE NETWORK

摘要

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.

主权项

1. A non-transitory computer-readable storage medium containing program instructions for managing the configuration of virtual switches from a central virtual machine management system in a virtual machine network, wherein execution of the program instructions by one or more processors causes the one or more processors to perform steps comprising:
establishing a communications connection between a virtual switch and a virtual machine management system using a first configuration; saving the first configuration; changing the configuration from the first configuration to a second configuration via the virtual machine management system; determining if the virtual machine management system is able to communicate with the virtual switch after the configuration is changed; if it is determined that the virtual machine management system is able to communicate with the virtual switch after the configuration is changed, then flushing the saved first configuration; and if it is determined that the virtual machine management system is not able to communicate with the virtual switch after the configuration is changed, then changing the configuration from the second configuration back to the first configuration using the saved configuration and reconnecting the virtual machine management system to the virtual switch using the first configuration.
