s51, reading a change control configuration from a change record table corresponding to the second control tool, wherein the change control configuration recorded in the change record table is a control configuration in which the second control tool executes a change operation on a control configuration set corresponding to the second virtual machine cluster within a target time period, and the target time period is a time period in which the second control tool cannot be connected with the first control tool;
And S52, updating the current control configuration set in the first storage space according to the change control configuration.
Optionally, in this embodiment, the above mentioned transmission of the target control configuration to the first control tool through the connection relationship under the condition that the second control tool operates normally, and describes a specific manner in which the second control tool may transmit the target control configuration to the first control tool through the connection relationship constructed by the LINK MODE, so as to implement full synchronization of the control configuration of the first control tool to the virtual machines in the second virtual machine cluster in the second control tool. After the first control tool performs full synchronization on the control configuration of the virtual machines in the second virtual machine cluster in the second control tool, if the control configuration of the virtual machines in the second virtual machine cluster in the second control tool is changed, the manner of synchronizing the changed control configuration to the first control tool by the LINK MODE is described as follows:
taking the scenario set forth in fig. 4 as an example, fig. 6 is a schematic diagram of a configuration information change synchronization according to an embodiment of the present application, where, as shown in fig. 6, a VCENTER-B changes the control configuration of a virtual machine in its second virtual machine cluster (for example, a new virtual machine, a delete virtual machine, and a change control configuration of a virtual machine), and after clicking a confirm or submit button, these changed change control configurations (corresponding to the control configuration in which the change operation is performed) are written into a database VCDB-B of the VCENTER-B, so as to permanently record the change operation. These change operations are then sent to the database VCDB-LMB of LINK MODE opposite VCENTER-A. If the LINK MODE opposite terminal VCENTER-a cannot access (may fail, be closed, etc.) at this time, these data will be recorded in the change record table of the database VCDB-B of the present VCENTER-B, and after the LINK MODE opposite terminal VCENTER-a is restored, the change control configuration is read from the change record table and then inserted into the VCDB-LMB. Specifically, fig. 7 is a schematic diagram of a read change record table according to an embodiment of the present application, as shown in fig. 7, after VCENTER-a returns to normal, the read change record table of VCENTER-B is read in the LINK MODE opposite VCENTER-B, and if there is no data, it is indicated that there is no control configuration change for the opposite VCENTER-B during the period of VCENTER-a failure. If so, the data in the change record table (corresponding to the change control configuration) is read and stored in the database VCDB-LMB of VCENTER-A.
Alternatively, in this embodiment, after waiting for the LINK MODE opposite terminal VCENTER-a to recover, the VCENTER-B may read the change control configuration from the change record table and send the change control configuration to VCENTER-a, where the received change control configuration is inserted into the VCDB-LMB.
As an alternative, after the storing the received control configuration set in the first storage space of the first control tool, the method further includes:
s61, receiving a target adjustment request, wherein the target adjustment request is initiated by the second control tool under the condition that the first control tool is detected to run normally, and the target adjustment request is used for requesting adjustment of the current control configuration set in the first storage space;
s62, responding to the target adjustment request, and executing a target adjustment statement on the first storage space, wherein the target adjustment statement is sent by the second control tool, and the target adjustment statement is used for indicating to adjust the current control configuration set.
Optionally, in this embodiment, when the first control tool and the second control tool both operate normally and the control configuration in the second control tool is changed, the changed control configuration may be synchronized by the target adjustment request, and ase:Sub>A specific synchronization manner may be that the second control tool sends ase:Sub>A target adjustment statement to the first control tool, where the target adjustment statement may be an SQL statement written in the change record table by the second control tool, and taking the scenario set up in fig. 4 as an example, the vcents structures of the LINK MODE are identical, and the database storage structures used are identical, so that the SQL statement when the VCENTER-B has the configuration change and operates the datase:Sub>A in the VCDB-B is also applicable to the VCDB-ase:Sub>A and VCDB-LMB databases of the VCENTER-ase:Sub>A of the LINK MODE. When VCENTER-B performs configuration change operation, the configuration change is converted into SQL sentences, one configuration operation may generate a plurality of SQL sentences, and the SQL sentences are executed in the database VCDB-B according to the sequence (operations such as adding control configuration, deleting control configuration, modifying control configuration and the like are related). Meanwhile, the VCENTER-B also records the SQL sentences and the execution sequence and sends the SQL sentences and the execution sequence to the VCENTER-A at the opposite end of the LINK MODE, and the VCENTER-A at the opposite end of the LINK MODE directly executes the SQL sentences and the execution sequence in the database VCDB-LMB after receiving the SQL sentences and the execution sequence so as to realize the synchronization of the two sides of the VCENTER-A and the VCENTER-B on the changed control configuration. When the VCENTER-A of the opposite terminal LINK MODE does not respond at the moment, the VCENTER-B records the SQL sentences and the execution sequence into a change record table of the VCENTER-B, and the VCENTER change record table is extracted and executed after the opposite terminal VCENTER-A is recovered, wherein the structure of the VCENTER change record table is as shown in the following table 1:
TABLE 1
As an alternative, executing the target adjustment statement on the first storage space further includes:
s71, adding a reference control configuration to the current control configuration set when the target adjustment statement is a first adjustment statement, wherein the first adjustment statement is used for indicating to add the reference control configuration, and the target adjustment statement comprises the first adjustment statement;
s72, deleting a reference control configuration from the current control configuration set when the target adjustment statement is a second adjustment statement, wherein the second adjustment statement is used for indicating to delete the reference control configuration, and the target adjustment statement comprises the second adjustment statement;
s73, when the target adjustment statement is a third adjustment statement, the reference control configuration in the current control configuration set is modified to be a candidate control configuration, wherein the third adjustment statement is used for indicating that the reference control configuration in the current control configuration set is modified to be the candidate control configuration, and the target adjustment statement comprises the third adjustment statement.
Optionally, in this embodiment, it is mentioned that after the configuration change operation is performed by VCENTER-B, the configuration change is converted into SQL statements, and one configuration operation may generate multiple SQL statements, and these SQL statements are executed in the database VCDB-B according to the sequence (related to operations of adding a control configuration, deleting a control configuration, modifying a control configuration, etc.), where a first adjustment statement is used for adding a control configuration, a second adjustment statement is used for deleting a control configuration, and a third adjustment statement is used for modifying a control configuration.
Taking the scenario set up in fig. 4 as an example, based on the above synchronization operation of the control configuration, the VCENTER-a may synchronize the control configuration in the VCENTER-B in real time, so that the VCENTER-a may control the virtual machines in the second virtual machine cluster of the VCENTER-B through the synchronized control configuration, when the LINK MODE opposite VCENTER-B is accessed in the VCENTER-a interface, if the opposite VCENTER-B is normal, the data of the virtual machines in the second virtual machine cluster in all the opposite VCENTER-B are returned to the local VCENTER-a through the opposite VCENTER-B, and then control is performed. If the opposite terminal VCENTER-B is abnormal, the VCENTER-A controls the virtual machines in the second virtual machine cluster through the control configuration information of the opposite terminal VCENTER-B stored in the local terminal VCDB-LMB. Fig. 8 is a schematic diagram of controlling a virtual machine across control tools according to an embodiment of the present application, as shown in fig. 8, in the foregoing manner, VCENTER-a (corresponding to control tool 10.49.33.118) and VCENTER-B (corresponding to control tool 10.49.33.119) of LINK MODE are mutually used, and virtual machine cluster information of two VCENTERs can be displayed on one interface through VCENTER-a.
The application provides a control method of a virtual machine, when two vcerters register with each other through a LINK MODE, the two vcerters registered with each other acquire all configuration information of the other vcerter through the other vcerter and then store the configuration information into a local vcerter, and when the configuration information of the other vcerter cluster cannot be accessed through the other vcerter (for example, the other vcerter is closed, down, failure, etc.), the configuration information of the other vcerter cluster stored into the local vcerter is displayed. When the opposite-end VCENTER cannot be used, when the content in the opposite-end VCENTER cluster is configured through the local VCENTER (such as adding virtual machine control configuration, deleting virtual machine control configuration, modifying virtual machine control configuration and the like), the changed configuration information is stored in a change record table of the local VCENTER, which is specially used for storing change information for the configuration information of the opposite-end VCENTER cluster, when the opposite-end VCENTER becomes available, the local VCENTER detects that the opposite-end VCENTER is recovered to be normal, and the local VCENTER synchronizes the modified configuration information into the opposite-end VCENTER so as to achieve the consistency of the configuration information in the two-end VCENTER. When both vcents are normal, after the vcents configure and modify their own cluster information, the modified configuration information is also synchronized to the opposite vcents. Any VCENTER on the LINK MODE is not available and does not affect the purpose of the operation of the rest VCENTER on the fault VCENTER cluster, thereby achieving the purpose of improving the usability of the VCENTER.
By the control method of the virtual machine, the VCENTER which is the LINK MODE can store one set of configuration data of the VCENTER at the opposite end, and the data of the VCENTER at the two ends can achieve the aim of synchronization through a synchronization mechanism. Through the processing mechanism, when any VCENTER fails, the management of two VCENTER clusters can be realized through the other VCENTER, so that the management and the use of a virtualization system are not affected when one VCENTER fails, and the availability of the virtualization system is improved.
