Part makes virtual machine network proper communication after generation migration or switching on and shutting down are restarted；All management nodes of cloud platform system are read
Take or change the network profile.
Wherein, the network switch is that virtual distributed interchanger has vlan universal formulations, the function of unified management.
Wherein, the calculate node provides the computing resource of virtual platform for calculate node server.
A kind of realization for distribution switch system based on xen virtual platforms that the present invention is provided based on another object
Method, it is theed improvement is that, what methods described was increased income by being installed in the calculate node in virtual platform
Openvswith virtual switches, the method for then issuing vlan message files using cluster is realized that the network of cluster is unified and configured
And management, and then realize distribution switch.
Wherein, methods described comprises the steps：
A, the systems of all calculate nodes in virtual platform started from xen kernels；
B, operating personnel download the virtual switch software of increasing income of latest edition from web interface；
C, by the virtual switch software design patterns of increasing income on the (SuSE) Linux OS of cloud platform；
The vlan information created on D, the establishment virtual machine vlan in every calculate node, every machine is completely the same；Institute
Stating vlan information includes vlan ID and vlan quantity；
E, the shared network profile of establishment cluster in the management node, are serviced with nfs and issued；
F, create after a virtual machine, network configuration information is inputted in the network profile；The network is matched somebody with somebody
Confidence breath includes virtual machine title, the affiliated vlan of network interface card；
G, virtual machine vlan information and network configuration are added to the (SuSE) Linux OS started shooting automatic perform script
In.
Wherein, in the step D, virtual machine vlan is created using the order of the virtual switch of increasing income；The network
The all of the port of exchange interface is respectively provided with vlan trunk allow all patterns, and at least one vlan is supported in each port.
Wherein, in the step E, the network profile includes three parameters；Respectively：Virtual machine id, virtual machine
Network interface card quantity vlan corresponding with virtual machine network interface card.
Compared with the prior art, the beneficial effect that reaches of the present invention is：
The distribution switch system and its implementation based on xen virtual platforms that the present invention is provided, when a Taiwan investment
When the virtual machine (vm) migration created on source host is on other physical resource main frames, due to all physical resources in cloud platform system
Main frame all reads the content of same configuration file, it is possible to ensure virtual machine (vm) migration come after vlan information it is consistent, really
Protecting network service also can normally move to specified resource host, it is ensured that network proper communication.
Brief description of the drawings
Fig. 1 is the distribution switch system diagram based on xen virtual platforms that the present invention is provided.
Embodiment
The embodiment to the present invention is described in further detail below in conjunction with the accompanying drawings.
