Example Embodiment
[0027] Example 1
[0028] This embodiment takes the CPU and memory resources on the physical host as an example to illustrate the process of resource scheduling for each physical host. The process is as follows: figure 2 As shown, including the following steps:
[0029] Step 100: Determine whether the utilization rate of various resources on each physical host reaches a set utilization rate;
[0030] Step 200: When the utilization rate of one or several resources (ie, some resources) on a certain physical host reaches the set utilization rate, then one or more virtual machines on the physical host are migrated to the resource that does not reach the set utilization rate. The utilization rate of all resources on the physical host after the migration operation is consistent.
[0031] Among them, all resources on the physical host include one or more of the following:
[0032] Central processing unit resources, memory resources, network resources, disk resources.
[0033] The consistent u...
Example Embodiment
[0034] Example 2
[0035] This embodiment is based on image 3 The scenario shown is an example to illustrate the method of resource scheduling for each physical host when creating a new virtual machine.
[0036] Among them, when the resource scheduling is initialized, the resources of each physical host are sufficient, so the newly created virtual machine can be deployed on any physical host under the premise of ensuring the load balance of each physical host;
[0037] When the utilization rate of one or several resources (that is, some resources) on one or more physical hosts reaches the set utilization rate, the virtual machines on the physical host whose utilization rate of some resources have reached the predetermined utilization rate are performed. Adjust to make full use of resources. Specifically, when a new virtual machine is to be created, one or more virtual machines on a physical host whose utilization of one or several resources reach the set utilization are migrated t...
Example Embodiment
[0040] Example 3
[0041] This embodiment introduces a resource scheduling system, which at least includes a judgment unit and a migration unit.
[0042] The judgment unit judges whether the utilization rate of each resource on each physical host reaches the set utilization rate;
[0043] The migration unit, when the judging unit judges that the utilization rate of one or several resources on the physical host reaches the set utilization rate, it migrates one or more virtual machines on the physical host to other resources that have not reached the set utilization rate On the physical host, the utilization of all resources on the physical host after the migration operation is consistent.
[0044] Among them, the migration unit makes the utilization of all resources on the physical host after the migration operation consistent refers to:
[0045] The difference between the utilization rates of various resources on the physical host after the migration operation of the migration unit is ...
