Problems solved by technology

If the storage system is not well designed to handle such an intensive input / output (I / O) load, it may eventually cause the virtual machine to start too slowly, or even some virtual machines cannot be started, affecting the normal use of users

example 1

[0098] Example 1: The virtual machines on the host computer include: VM1-VM400, a total of 400 virtual machines.

[0099] And the virtual machines VM1-VM100, VM201-VM300 are all created using the Windows 7 template win7templete; the virtual machines VM101-VM200, VM301-VM400 are all created using the Windows 10 template win10templete.

[0100] After determining the system templates of each virtual machine, the virtual machines can be divided into two categories based on the system templates of each virtual machine, one of which includes virtual machines VM1-VM100, VM201-VM300, and the corresponding system template is win7templet; The other category includes virtual machines VM101-VM200, VM301-VM400, and the corresponding system template is win10templete.

[0101] When the host monitors the trigger event generated by the virtual machine snapshot, it determines that the virtual machines corresponding to the trigger event generated by the virtual machine snapshot include: VM1-VM40...

example 2

[0135] Example 2: After the memory snapshot files of the virtual machines VM1-VM400 are generated based on the above-mentioned example 1, when a trigger event for batch startup of the virtual machines is detected, the following steps can be adopted to start the virtual machines VM1-VM400 in batches:

[0136] The virtual machine VM1 is started first; here, the virtual machine VM1 started first is randomly determined.

[0137] The host recognizes that the system template of the virtual machine VM1 is win7templete.

[0138] Since the virtual machine VM1 is started first, the base memory snapshot file of win7temple does not exist in the common memory area of ​​the host machine at this time, so the base memory snapshot file base1 of the virtual machine VM1 is loaded into the common memory area.

[0139] Copy base1 from the memory public area to the memory of the virtual machine VM1, and load the extended memory snapshot file extend1 of the virtual machine VM1 into the memory of VM1...

Abstract

The embodiment of the invention provides a virtual machine starting method and a device, and the method comprises the steps: monitoring a trigger event of batch starting of virtual machines; when triggering events of batch starting of the virtual machines occur, memory snapshot files corresponding to the multiple target virtual machines triggered and started by the triggering events are obtained;and starting the plurality of target virtual machines based on the memory snapshot files respectively corresponding to the plurality of target virtual machines. According to the embodiment of the invention, the virtual machine can be quickly started through the virtual machine memory snapshot file, the data volume of reading the data from the storage system in the batch starting process of the virtual machine is reduced, and the situation that the virtual desktop is started too slowly or even cannot be started due to resource limitation in the batch starting process is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of virtual machines, and in particular, to a method and device for starting a virtual machine. Background technique [0002] Virtual Desktop Infrastructure (Virtual Desktop Infrastructure, VDI), also known as client virtualization or desktop virtualization, is a virtual machine running Microsoft Windows operating system Windows 7 or Windows 10 on a virtualized host machine in the data center. There are various application frontends for desktop virtualization. The user connects to the remote virtual desktop by using a protocol such as Remote Desktop Protocol (Remote Desktop Protocol, RDP) from the client device, so as to realize access to the remote virtual desktop. [0003] When a large number of virtual desktops are started at the same time in a short period of time, for example, from 9:00 a.m. to 5:00 p.m. every working day, multiple virtual machines running virtualized desktops will be started i...
