Embodiment 2

[0154] On the basis of Embodiment 1 of the management server of the present invention, optionally, the adjustment module 602 is specifically used for:

[0155] Use the following formula (1) to determine the load balance degree σ1 of the mth virtual group:

[0156] ρ 1 = 1 N Σ i = 1 N ( x i - μ ) 2 - - - ( 1 )

[0157] Among them, N is the number of physical servers in the virtualization cluster; x i is the resource occupancy rate of the virtual machines belonging to the m-th virtual machine group on the physical server i, where m is ...

Embodiment 3

[0163] On the basis of Embodiment 1 or Embodiment 2 of the management server of the present invention, optionally, the adjustment module 602 is specifically used for:

[0164] According to the resource occupancy rate of the virtual machines belonging to the nth virtual machine group on each physical server, it is determined that the virtual machine to be migrated needs to be migrated from the source physical server to the target physical server; wherein the virtual machine to be migrated is the virtual machine of the nth virtual machine group A virtual machine; wherein, n is less than K;

[0165] Determine whether the remaining resources of the target physical server are greater than the resources required by the virtual machine to be migrated;

[0166] If yes, then migrate the virtual machine to be migrated to the target physical server;

[0167] Otherwise, on the target physical server, the virtual machine belonging to the kth virtual machine group is migrated from the targ...

Abstract

The invention provides a method and a device for dispatching dynamic resources of a virtual cluster. The virtual cluster comprises at least one management server and a plurality of physical servers, one or a plurality of virtual machines are deployed on the physical servers, and businesses run on the virtual machines. The method includes the steps: determining business priorities corresponding to each virtual machine group in K virtual machine groups by the management servers; sequentially performing virtual machine deployment and adjustment for the K virtual machine groups by the management servers according to the order of the business priorities from high to low. The virtual machine groups run the same businesses, and resources occupied by the virtual machines belonging to the same virtual machine group in each physical server are balanced.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a method and device for Dynamic Resources Scheduling (DRS, Dynamic Resources Scheduling) of a virtualized cluster. Background technique [0002] In the virtualization technology, multiple virtual machines can be deployed on a single physical server by virtualizing the physical server, thereby effectively improving the resource occupancy rate of the physical server. Among them, a resource pool composed of multiple physical servers deployed with virtual machines is called a virtualization cluster. [0003] DRS is an important feature of virtual clusters; in the prior art, the methods for implementing DRS mainly include: the cluster management system regularly monitors the resource occupancy rate of each physical server; and migrates some virtual machines on physical servers with high resource occupancy To the physical server with low resource usage rate, realize the...
