[0045] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0046] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0047] According to one aspect of the present invention, an embodiment of the present invention provides a resource scheduling method for a virtual machine, such as Figure 1 As shown, it may include the steps of:

[0048] S1, in response to a storage pool triggering a preset rule, determining a number of hosts corresponding to the storage pool;

[0049] S2, determining a virtual machine to be subjected to data migration and a source host among a plurality of hosts according to a preset rule triggered by the storage pool;

[0050] S3, obtaining load parameters of several other storage pools mounted by each of the hosts;

[0051] S4, determining a target host and a target storage pool among several other storage pools mounted under the target host according to the load parameter;

[0052] S5, migrating the data of the virtual machine to be migrated from the storage pool to the target storage pool mounted on the target host.

[0053] The solution proposed in the present invention can automatically schedule storage pool resources to achieve load balancing of the storage pool.

[0054] In some embodiments, the OCFS cluster file system can be used to implement basic management of the file system through the 02cb service, and any node in the cluster can access the storage device in parallel. The storage pool device type supports local disks of server nodes, shared disks of SCSI services provided by SAS and ATA disks, and disks of distributed storage pools.

[0055] In this way, multiple storage pools of different types can be mounted on each host. Multiple storage pools can include storage pools that are exclusive to the host or storage pools shared with other hosts. In addition, the storage pool has a special tree structure. You only need to create a separate DRS directory, which can also be called a storage cluster. Add different storage pool resources to the storage cluster for management. In addition to automatically recommending the best storage resources when creating, cloning, or migrating VMs, it can also trigger preset rules when a storage pool on the host has an increased storage rate or excessive IO pressure due to the continuous growth of business data of the virtual machine, which exceeds the trigger threshold.

[0056] In some embodiments, in response to a storage pool triggering a preset rule, determining a number of hosts corresponding to the storage pool further includes:

[0057] Obtain the usage rate and IO pressure value of the storage pool at preset time intervals;

[0058] In response to a usage rate of the storage pool being greater than a usage rate threshold, the storage pool triggers a first preset rule;

[0059] In response to the IO pressure value of the storage pool being greater than a pressure threshold, the storage pool triggers a second preset rule.

[0060] Specifically, the normal operation of a virtual machine depends not only on whether the CPU and memory resources of the host where it is located are sufficient, but also on whether the storage resources where it is located are sufficient. In order to ensure the storage resources required by the running virtual machines, multiple different storage pools can be managed in a clustered manner. With the increase of virtual machine business data, when the usage rate or IO pressure of a storage pool in the cluster is high, the storage pool will generate a corresponding alarm, or the usage rate and IO pressure of the storage pool can be detected at preset time intervals. If the usage rate or IO pressure exceeds the set scheduling threshold, the scheduling of the storage cluster will be triggered. At this time, the background can obtain the storage usage of all storage and the %util value of IO pressure (a few percent of a second is used for IO operations), and obtain through monitoring whether the usage rate of a storage pool in the cluster pool is higher than the set threshold, or the %util value is higher than the threshold.

[0061] In some embodiments, determining a source host among a plurality of hosts and a virtual machine on the source host to be migrated data according to a preset rule triggered by the storage pool further includes:

[0062] In response to the virtual machine triggering a first preset rule, determining the virtual machine to be migrated according to the largest virtual machine file in the storage pool, and further determining the source host according to the virtual machine to be migrated;

[0063] In response to the virtual machine triggering the second preset rule, a virtual machine with the largest virtual machine file among the shut down virtual machines in the plurality of hosts is used as the virtual machine to be migrated, and then the source host is determined according to the virtual machine to be migrated.

[0064] Specifically, if the usage rate of a storage pool is higher than a threshold, the disk files of all virtual machines on the storage pool can be sorted by size, and the largest disk file can be obtained as the migration object. The virtual machine to be migrated and the source host where the virtual machine is located can be determined through the largest disk file. If the %util value is higher than or equal to the set threshold, because the IO operation of the original storage pool is relatively frequent at this time, the virtual machine with the largest virtual machine file among the virtual machines in the shutdown state of several hosts will be used as the virtual machine to be migrated.

[0065] In some embodiments, obtaining load parameters of several other storage pools mounted by each of the hosts further includes:

[0066] In response to the storage pool triggering a first preset rule, obtaining current usage rates of a plurality of other storage pools mounted by each of the hosts;

[0067] In response to the storage pool triggering a second preset rule, current IO pressure values ​​of several other storage pools mounted by each of the hosts are obtained.

[0068] In some embodiments, determining a target host and a target storage pool among several other storage pools mounted under the target host according to the load parameter further includes:

[0069] In response to the storage pool triggering a first preset rule, determining whether current usage rates of a plurality of other storage pools mounted on the source host are all greater than a first preset value;

[0070] In response to the existence of other storage pools whose current usage rate is less than the first preset value, taking the storage pool whose usage rate is less than the first preset value as the target storage pool and taking the source host as the target host;

[0071] In response to the current usage rates of several other storage pools being greater than the first preset value, other storage pools whose current usage rates are less than the first preset value are randomly mounted from other hosts as target storage pools.

[0072] In some embodiments, it also includes:

[0073] In response to the storage pool triggering a second preset rule, determining whether current IO pressure values ​​of a plurality of other storage pools mounted under the source host are all greater than a second preset value;

[0074] In response to the existence of other storage pools whose current IO pressure value is less than the second preset value, taking the storage pool whose current IO pressure value is less than the second preset value as the target storage pool and taking the source host as the target host;

[0075] In response to the current IO pressure values ​​of several other storage pools being greater than the second preset value, other storage pools mounted in other hosts and having current IO pressure values ​​less than the second preset value are used as target storage pools.

[0076] Specifically, when the first preset rule is triggered, the storage pools in the cluster with IO pressure values ​​lower than the first preset value can be sorted by the current usage rate, and the storage pool with the smallest usage rate mounted on the same host is preferentially obtained as the target storage pool for scheduling. If there is no applicable storage pool on the same host, other storage pools are traversed and the storage pool with the smallest usage rate is used as the target storage, and then the data in the original storage pool is obtained and migrated to the target storage pool. When the second preset rule is triggered, the storage pools in the cluster with IO pressure values ​​lower than the second preset value can be sorted by the current IO pressure values, and the storage pool with the current IO pressure value mounted on the same host is preferentially obtained as the target storage pool for scheduling. If there is no applicable storage pool on the same host, other storage pools are traversed and the storage pool with the current IO pressure value is used as the target storage, and then the data in the original storage pool is obtained and migrated to the target storage pool.

[0077] In some embodiments, it also includes:

[0078] The data of the virtual machine to be migrated in the storage pool is deleted.

[0079] Specifically, after the data migration is completed, the virtual machine disk files of the original storage pool are deleted, and the alarms generated by the original storage pool automatically disappear from the historical alarm list.
