Embodiment Construction

[0086] see figure 1 , is a schematic diagram of a host cluster, which may include: a host 10, a host 20, and a host 30, wherein, the host 10 may be configured with VM 101, VM 102, ... VM10n (wherein, n indicates that in the host 10 The total number of configured VMs, the value of n is an integer greater than 1), similarly, VM 201, VM 202, ... VM20m can be configured on the host 20 (wherein, m represents the total number of VMs configured in the host 20, m is an integer greater than 1), the host 30 can be configured with VM 301, VM 302, ... VM 30k (wherein, k represents the total number of VMs configured in the host 30, and the value of k is an integer greater than 1) . It should be noted that the above figure 1 The shown host cluster is only an exemplary illustration for illustrating the application scenario of the embodiment of the present application, and the host cluster may also include more hosts.

[0087] Taking the host 10 as an example, assuming that the host memory...

Abstract

The embodiment of the invention discloses a virtual machine scheduling method and device. The method and the device are applied to host cluster. The host cluster comprises a plurality of hosts. Each host is configured with a plurality of virtual machines (VMs). The method comprises the following steps: putting a VM with a to-be-processed task in a host cluster into a plurality of threads, whereineach thread comprises a preset number of VMs; using a multi-thread queuing batch processing mechanism; each thread sequentially processing the to-be-processed tasks of the VMs included in the thread;that is to say, the condition that the previous thread meets the preset condition being used as a condition for triggering the next thread to begin to process the to-be-processed task of the VM included in the next thread. Therefore, the problem that the performance of the host and the normal operation of the virtual machine on the host are influenced due to the fact that the memory of the host inthe host cluster is excessively divided when a large number of tasks to be processed are simultaneously operated in parallel is avoided. The excessive division of the memory of the host can be effectively avoided to a certain extent, and the normal operation of the host and the virtual machine on the host is ensured.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a virtual machine scheduling method and device. Background technique [0002] Usually, multiple virtual machines (English: Virtual Machine, VM for short) are configured on the host, and each VM runs independently on the host, and various software and applications can be installed on these VMs to enrich the services supported on the host , to improve host performance. The host is configured with host memory, and the configured memory will also be allocated to it when the VM is built on it, and each host determines any value between 0.8 and 1.2 as the virtualization degree. [0003] However, in order to ensure the normal operation of the host and its virtual machines, it is necessary to ensure that the host does not overprovision, that is, ensure that the sum of the configured memory of all VMs built on the host does not exceed the product of the host memory and th...
