Also it should be noted that, the communication quality information that Virtual Machine Manager module can send according to the server received, real-time renewal and maintenance are carried out to communication quality matrix, to improve the reliability of this communication matrix, and then ensure that the virtual machine carrying out disposing and moving according to this communication matrix can carry out normal communication with the opposite end virtual machine that there is communication traffic.

There is the opposite end virtual machine of communication traffic in step 405, inquiry and object virtual machine.Perform step 406.

This object virtual machine is virtual machine to be migrated or waits to dispose virtual machine.In embodiments of the present invention, when data center determines to need dilatation according to traffic load, can dispose new virtual machine in the server of Virtual Machine Manager module management, this new virtual machine is to be waited to dispose virtual machine; Under certain server of data center occurs that exception, data center network fault or certain server need the situations such as active maintenance, need on the virtual machine (vm) migration occurring disposing in abnormal server to other server, the virtual machine disposed in this abnormal server is virtual machine to be migrated.When after Virtual Machine Manager module determination object virtual machine, the opposite end virtual machine that there is communication traffic with this object virtual machine can be inquired about in a database.Example, hypothesis goal virtual machine disposes virtual machine VM7 for waiting, then Virtual Machine Manager module polls to treat to dispose with this opposite end virtual machine that virtual machine VM7 exists communication traffic can be VM8 and VM9.

It should be noted that, when certain switching node of data center breaks down, the communication between multiple VM of this switching node can be caused all to receive impact, now Virtual Machine Manager module needs affected abnormal virtual machine to move in other servers, in abnormal virtual machine transition process, excessive for avoiding data center's impact, abnormal virtual machine to be migrated to be reduced as far as possible, therefore, in Virtual Machine Manager module before inquiry exists the opposite end virtual machine of communication traffic with object virtual machine, also need to determine object virtual machine from abnormal virtual machine, namely abnormal virtual machine to be migrated.Fig. 4-3 is a kind of method flow diagrams determining object virtual machine from abnormal virtual machine that the embodiment of the present invention provides, and as shown in Fig. 4-3, the method comprises:

Step 4051, this abnormal virtual machine of instruction receiving abnormal virtual machine transmission and other virtual machine communication states are the communication abnormality information of abnormality.Perform step 4052.

In embodiments of the present invention, when the communication state that virtual machine detects between other virtual machines is abnormality, communication abnormality information can be sent to Virtual Machine Manager module.Example, when supposing that the communication state that virtual machine VM1 detects between virtual machine VM2 is abnormality, VM1 can send communication abnormality information to Virtual Machine Manager module.

Step 4052, according to this communication abnormality information, determine the abnormal server being deployed with this abnormal virtual machine.Perform step 4053.

Example, Virtual Machine Manager module according to the communication abnormality information received, can determine that the abnormal server being deployed with this abnormal virtual machine VM1 is: server A.

The number of the abnormal server in the server of step 4053, statistics Virtual Machine Manager module management.

If the number of the abnormal server in the server of this Virtual Machine Manager module management equals 1, perform step 4054; If the number of the abnormal server in the server of this Virtual Machine Manager module management is greater than 1, perform step 4055.Example, Virtual Machine Manager module is determining that the abnormal server being deployed with abnormal virtual machine VM1 is: after server A, the number can adding up the abnormal server in the server of this Virtual Machine Manager module management is 1, and performs step 4054.

Step 4054, this abnormal virtual machine is defined as this object virtual machine.

If the number of the abnormal server in the server of this Virtual Machine Manager module management equals 1, then this abnormal virtual machine is defined as this object virtual machine.Example, suppose that the abnormal server that Virtual Machine Manager module is determined is: server A, then because the number of this abnormal server is 1, then abnormal virtual machine VM1 can be defined as object virtual machine by Virtual Machine Manager module.

Step 4055, inquiry communication matrix, the communication state adding up each abnormal server and other abnormal server is the number of times of abnormality.Perform step 4056.

If the number of the abnormal server in the server of this Virtual Machine Manager module management is greater than 1, then Virtual Machine Manager module can inquire about communication matrix, and the communication state adding up each abnormal server and other abnormal server is the number of times of abnormality.Example, suppose virtual machine VM1, VM2 and VM5 have sent communication abnormality information to Virtual Machine Manager module, Virtual Machine Manager module determines that the abnormal server being deployed with abnormal virtual machine VM1 is: server A, the abnormal server being deployed with abnormal virtual machine VM2 is: server B, the abnormal server being deployed with abnormal virtual machine VM5 is: server C, then because the number of this abnormal server is 3, be greater than 1, therefore Virtual Machine Manager module can inquire about communication matrix, the communication state adding up abnormal server A-C and other abnormal server is respectively the number of times of abnormality.As can be seen from the communication matrix shown in table 1, the communication state of abnormal server A and abnormal server B is normal condition, be abnormality with the communication state of abnormal server C, then Virtual Machine Manager module can determine that the communication state of abnormal server A and other abnormal server B and C be the number of times of abnormality is 1; In like manner, it be the number of times of abnormality is 1 that Virtual Machine Manager module can also add up the communication state obtaining abnormal server B and other abnormal server, and the communication state of abnormal server C and other abnormal server is the number of times of abnormality is 2.

Step 4056, be that the server that the number of times of abnormality is maximum is defined as destination server by communication state.Perform step 4057.

Example, due in abnormal server A-C, the communication state of abnormal server C and other abnormal server is the number of times of abnormality is 2, and communication state is that the number of times of abnormality is maximum, then this abnormal server C can be defined as destination server by Virtual Machine Manager module.

Step 4057, the abnormal virtual machine of disposing in this destination server is defined as this object virtual machine.

In embodiments of the present invention, if be also deployed with other virtual machines in this destination server, but other virtual machines do not send anomalous communication information to Virtual Machine Manager module, namely these other virtual machines are not abnormal virtual machine, then these other virtual machines can not be also defined as object virtual machine by Virtual Machine Manager module.Example, the abnormal virtual machine VM5 disposed in destination server C can be defined as object virtual machine by Virtual Machine Manager module, i.e. virtual machine to be migrated.If also deploy virtual machine VM6 in destination server C, but VM6 normally can perform communication traffic with the opposite end virtual machine that there is communication traffic, then VM6 need not be defined as virtual machine to be migrated by Virtual Machine Manager module.

Step 406, determine the server being deployed with this opposite end virtual machine.Perform step 407.

The virtual machine disposed in each server can be recorded in the database of Virtual Machine Manager module, therefore after Virtual Machine Manager module determines the opposite end virtual machine that there is communication traffic with object virtual machine, the virtual machine disposed in each server can be inquired about, determine the server being deployed with opposite end virtual machine.Example, suppose Virtual Machine Manager module polls to be VM8 and VM9 with the opposite end virtual machine waiting to dispose virtual machine VM7 and exist communication traffic, then Virtual Machine Manager module can determine that the server being deployed with virtual machine VM8 is server G, and the server being deployed with virtual machine VM9 is server H.

Step 407, from preset communication matrix obtain destination server, this destination server and this communication state being deployed with the server of this opposite end virtual machine are normal condition.Perform step 408.

In embodiments of the present invention, have recorded the communication state between any two servers in this communication matrix, this communication state comprises normal condition or abnormality.If the server being deployed with opposite end virtual machine comprises multiple server, then the communication state between this destination server and the plurality of server should be normal condition.Example, for the server G and the server H that are deployed with virtual machine VM8 and VM9, known by the communication matrix shown in question blank 1, the server being normal condition with the communication state of this server G and server H comprises: server E, server F, server G and server H, then server E-H can be defined as destination server by Virtual Machine Manager module.If the communication state that Virtual Machine Manager module does not get the server being deployed with opposite end virtual machine with this from the communication matrix preset is the destination server of normal condition, then can according to the size of the cpu resource of managed each server, the destination server that the size of storage resources and the size of network interface bandwidth select suitable server to dispose as VM and move.

It should be noted that, if this object virtual machine is virtual machine to be migrated, after Virtual Machine Manager module obtains destination server from the communication matrix preset, also need from this destination server, the source server being deployed with this virtual machine to be migrated to be deleted, and using the server except this source server as object service.Example, suppose that server E breaks down to need to safeguard, Virtual Machine Manager module needs the virtual machine VM0 disposed in this server E to migrate to other servers, the virtual machine that there is communication traffic with this virtual machine VM0 is: virtual machine VM8 and VM9, the server being wherein deployed with virtual machine VM8 is server G, the server being deployed with VM9 is server H, known by the communication matrix shown in question blank 1, the server being normal condition with the communication state of server G and server H comprises: server E, server F, server G and server H, then server E-H can be defined as destination server by Virtual Machine Manager module, because the server E in destination server is for being deployed with virtual machine to be migrated: the source server of VM0, therefore Virtual Machine Manager module need from destination server by this source server: server E deletes, now, destination server after renewal is: server F, server G and server H.

Step 408, add up the number of this destination server.

If the number of this destination server equals 1, perform step 409; If the number of this destination server is greater than 1, perform step 410; If the number of this destination server is less than 1, then Virtual Machine Manager module can determine that the communication state not getting the server being deployed with opposite end virtual machine with this from the communication matrix preset is the destination server of normal condition, then can according to the size of the cpu resource of managed each server, the destination server that the size of storage resources and the size of network interface bandwidth select suitable server to dispose as VM and move.Example, suppose that the destination server that Virtual Machine Manager module obtains is: server E, server F, server G and server H, then Virtual Machine Manager module can add up the number obtaining this destination server is 4, is greater than 1, therefore performs step 410.

Step 409, by this object deploying virtual machine in this destination server.

If the number of this destination server equals 1, then Virtual Machine Manager module can directly by this object deploying virtual machine in this destination server.

Step 410, from the set of this destination server, select deployment server according to preset rules.Perform step 411.

If the number of this destination server is greater than 1, then Virtual Machine Manager module can select deployment server according to preset rules from the set of this destination server.Example, Virtual Machine Manager module can from the set of destination server, { server E, server F, server G, select deployment server in server H} according to preset rules.

Fig. 4-4 is a kind of method flow diagrams selecting deployment server from the set of destination server that the embodiment of the present invention provides, and as shown in Fig. 4-4, the method comprises:

Step 4101, from the server of Virtual Machine Manager module management screening meet the alternate servers set of the standard of parameter preset.

This parameter preset comprises at least one in cpu resource, storage resources and network interface bandwidth.In embodiments of the present invention, Virtual Machine Manager module can according to parameters such as the CUP of object virtual machine and internal memories, and in the server of Virtual Machine Manager module management, screening meets the alternate servers set of the standard of parameter preset.Example, hypothesis goal virtual machine disposes virtual machine VM7 for waiting, parameter preset is cpu resource, storage resources and network interface bandwidth, Virtual Machine Manager module according to the standard of the parameter preset that the CPU of virtual machine VM7 and internal memory set is: the dominant frequency of CPU is more than 4 GHzs (GHz), storage resources is more than 8 GB (GB), network interface bandwidth is more than 10 MBPSs (Mbps), the alternate servers set meeting the standard of above-mentioned parameter preset that then Virtual Machine Manager module is screened from the server of this Virtual Machine Manager module management can be { server A, server E, server F, server G}.

Step 4102, screen server identical with the set of this destination server in this alternate servers set and obtain alternative deployment server set.

Virtual Machine Manager module can get common factor to the set of alternate servers set and destination server, obtains alternative deployment server set.Example, the set of hypothesis goal server is { server E, server F, server G, server H}, the alternate servers set of Virtual Machine Manager module screening is { server A, server E, server F, server G}, then Virtual Machine Manager module is occured simultaneously to these two server set conjunction, screens the alternative deployment server set obtained can be: { server E, server F, server G}.

Step 4103, from this alternative deployment server set, select deployment server according to compatibility algorithm.

Compatibility algorithm refers to from alternative deployment server set, and the server that between the server selecting and be deployed with opposite end virtual machine, communication path is the shortest is as deployment server.Example, suppose that the opposite end virtual machine that there is communication traffic with object virtual machine VM7 is VM8 and VM9, the server being deployed with VM8 is server G, the server being deployed with VM9 is server H, then as can be seen from the network topology structure shown in Fig. 4-2, alternative deployment server set { server E, server F, in server G}, and the server that between server G, communication path is the shortest is server G, and the server that between server H, communication path is the shortest is also server G, then server G can be chosen as deployment server by Virtual Machine Manager module.

It should be noted that, except compatibility algorithm, Virtual Machine Manager module can also from alternative deployment server set Stochastic choice server as deployment server.

Step 411, by this object deploying virtual machine in this deployment server.

Example, object virtual machine VM7 can be deployed in deployment server by Virtual Machine Manager module: in server G.
