Exemplarily, identification information comprises IP address information, host name information, domain name addresses information.
Provided by the present invention for more complete description, below by an example, specifically describe the method for switching network of dummy machine system migration provided by the present invention.
Referring to shown in Fig. 3 to 5, Fig. 3 to Fig. 5 illustrates the schematic flow sheet of a kind of embodiment of method for switching network of dummy machine system migration provided by the present invention.Between source network and objective network, can communicate by the Internet, the network switched system of dummy machine system migration can arrange management server in the drawings, also the part unit of the network switched system of dummy machine system migration can be arranged on source physical host or target physical main frame.
Physical host in two networks of management service management and with the dummy machine system being moved, two physical host A and B lay respectively at source network and objective network, and the dummy machine system VM1 of source physical host A operation is moved to target physical host B.
Can be in the time that management server be received virtual machine (vm) migration order, start the network of method provided by the present invention in moving and switch, concrete operating procedure is as follows:
First, as shown in Figure 3, for VM1 increases and original the same number of virtual machine network interface card, VM1 had network interface card NC1 originally, and IP address is 10.1.1.1, now a newly-increased network interface card NC2.According to new IP configuration information after migration, NC2 is carried out to corresponding configuration, the IP address that NC2 is set is 20.2.2.2.Between new Microsoft Loopback Adapter NC2 and target physical host B, set up IP tunnel, then carry out the operation of online migration dummy machine system;
Next, as shown in Figure 4, when VM1 is carrying out in the process of cross-domain online migration, if have newly-increased connection or find that there is the connection of being convenient to switching in transition process, being connected to of for example having in transition process, occur that non-migrating causes in have no progeny and reconnect, or the initiatively communication connection of initiation of dummy machine system, controlling dummy machine system utilizes IP tunnel and the Correspondent Node newly increasing to carry out network service, use the connection setting (20.2.2.2) of objective network to send connection request to Correspondent Node by NC2, dummy machine system passes through IP tunnel to objective network by NC2 and carries out interim communicating by letter with Correspondent Node.
Next, management server can be set up respectively source agent unit and target proxy unit at source physical host A and target physical host B, wherein, source agent unit is preserved the configuration information of source network and the configuration information of objective network of VM1, the configuration information of source network comprises the IP address 10.1.1.1 of NC1, and the configuration information of objective network comprises the IP address 20.2.2.2 of NC2.The source network configuration information of VM1 can be preserved in target proxy unit, for the release of migration and proxy resources again.
In the time that VM1 enters shutdown migration phase, completing after shutdown migration, on target physical main frame, move dummy machine system, delete old Microsoft Loopback Adapter and IP tunnel that dummy machine system has, complete a network in the cross-domain migration of dummy machine system and switch.After having moved, dummy machine system again initiates to connect by the network configuration from new.
In the time that above-mentioned VM1 enters shutdown migration phase; can start respectively the agent functionality of the upper source of physical host A, B agent unit, target proxy unit; and interrupt the original network of dummy machine system and connect; delete original network configuration; after completing, migration deletes the former Microsoft Loopback Adapter NC1 of dummy machine system; the configuration of deletion IP tunnel, discharges the resource of occupying in migration.
As Fig. 5, after migration completes, in the time that new connection request sends to the old Microsoft Loopback Adapter of source physical host A (1), by the source agent unit of source physical host A, be the network IP that VM1 is new by the object IP information Reseal of connection request bag, and carrying out Connection Service (2) newly asking to be sent to VM1, VM1 is receiving after connection request bag, is connecting processing (3) according to packet information by source IP.
In addition, in the time receiving the instruction message that again carries out cross-domain migration, first target proxy unit on target physical host B identifies whether migration is again to move back to source network, can identify by the identification information of network, and for example IP address and subnet mask are identified.
Target proxy cell response is identical with the identification information of source network in the identification information of objective network of migration again, judges that VM1 moves back source network.The source agent unit dummy machine system of target proxy unit on can notification source physical host A moved back to this locality, and using the identification information of source network as the identification information of the objective network of migration again, using the identification information of objective network as the identification information of the source network of migration again, and using source physical host as the target physical main frame again moving, using target physical as the source physical host again moving, carry out according to the method described above network switching, again carry out operation and the subsequent operation of the identical and corresponding identical new Microsoft Loopback Adapter of network type of old Microsoft Loopback Adapter number that on the dummy machine system moving, increase has with dummy machine system on the physical host of source.
If judge, VM1 non-migrating return source network, can set up new agent unit at the target physical main frame of migration more according to the method described above, the information of the source physical host A of its preservation is transmitted to new target proxy unit by target physical host B simultaneously, and after migration completes, discharge the target proxy element resources of target physical host B.
So far, described in detail according to method for switching network and the system of a kind of dummy machine system migration of the present invention.For fear of covering design of the present invention, details more known in the field are not described.Those skilled in the art, according to description above, can understand how to implement technical scheme disclosed herein completely.
