Problems solved by technology

[0003] At present, only vmware can provide VDS function in the field of virtualization technology. The open source ovs (short for openvswtich open source virtual switch) can support vlan division and other functions on a single physical host, but it cannot provide cross-node distributed switches Function
And after the virtual machine is migrated or switched on and off, the vlan information will be deleted

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The distributed switch system based on the xen virtualization platform provided by the present invention is such as figure 1 As shown, the distributed switch system includes a management node, a network switch, a computing node, a fiber switch and a shared storage; the management node, the network switch, the computing node, the fiber switch and the shared storage are connected in sequence. The distributed switch system is included in the cloud platform system.

[0026] The management node is a file system server, which is used to provide a network configuration file. The network configuration file enables the virtual machine to communicate normally after the virtual machine is migrated or switched on and off; all servers of the cloud platform system read or modify the network configuration file . The network sw...

Abstract

The invention relates to a distributed switch system based on an xen virtualization platform and an achieving method thereof. The distributed switch system is included in a cloud platform system and comprises a management node, a network switch, a management node I, an optical fiber switch and a sharing storage. The management node, the network switch, the management node I, the optical fiber switch and the sharing storage are sequentially connected. The system combines an open-source virtual switch (for short ovs) and achieves the distributed switch on a plurality of physical nodes, a virtual machine can shift among a plurality of physical resource main machines or store vlan information after startup and shutdown, and a network still conducts communication normally.

Description

technical field [0001] The invention relates to a distributed switch system and its implementation method, in particular to a distributed switch system based on a xen virtualization platform and its implementation method. Background technique [0002] The biggest difference between VDS (Virtual Distributed Switching System) and VSS (Virtual Switching System) is that it is the same virtual switch for all associated hosts. On the same virtual switch, this allows virtual machines to migrate across physical hosts, and ensures that network configurations are consistent and network communication information of virtual machines is preserved. [0003] At present, only vmware can provide VDS function in the field of virtualization technology. The open source ovs (short for openvswtich open source virtual switch) can support vlan division and other functions on a single physical host, but it cannot provide cross-node distributed switches Features. And after the virtual machine is mi...
