Problems solved by technology
[0003] However, there is currently no specific solution to the boot storm problem faced by the desktop cloud
Most of the existing technologies minimize the impact of boot storms by replacing high-throughput storage, but they cannot fundamentally solve the boot storm problem.

Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.
[0040] In a first aspect, the present invention provides a method for solving a virtual machine startup storm, such as figure 1 As shown, the method includes:
[0041] When a virtual machine startup request is received, it is judged whether there is a basic image file of the virtual machine to be started in the memory disk;
[0042] If so, start the virtual machine to be started by using the basic image file of the virtual machine to be star...

The invention relates to a method and device used for solving boot storm of a virtual machine. The method comprises following steps: determining whether basic mirror image documents of a to-be-started virtual machine are present or not in a memory disk when receiving a starting request of the virtual machine; utilizing the basic mirror image documents to start the to-be-started virtual machine if so; copying the basic mirror image documents of the to-be-started virtual machine into the memory disk otherwise and utilizing the basic mirror image documents of the to-be-started virtual machine in the memory disk to start the to-be-started virtual machine; and mounting an internal memory to internal space of a local operation system after the memory disk is started by the local operation system. The method and device used for solving boot storm of the virtual machine have following beneficial effects: the basic mirror image documents corresponding to the memory disk are utilized to start the virtual machine; the memory disk is the internal space which is mounted into the local operation system by the internal memory; operation speed of the memory disk is fairly higher than that of a disk; the memory disk is capable of dealing with a deluge of reading operation; and even if many users start the virtual machine, the occurrence of boot storm can be avoided.
Description
technical field [0001] The invention relates to the technical field of virtual machines, in particular to a method and device for solving virtual machine startup storms. Background technique [0002] With the rapid development of cloud computing technology, desktop cloud applications have been gradually adopted by governments and various enterprises. For desktop cloud applications, the biggest management problem is to ensure the smooth operation of the system when the number of storage input / output is at its peak. However, when many users start the system and load applications at the same time, both the operating system and the applications need to perform many read operations on the disk, which takes up a lot of resources. If these operations are multiplied by the hundreds of desktops that users are starting , resulting in I / O times that can quickly overwhelm a storage array, ie, create a boot storm. Boot storms don't go away easily and usually have a significant impact o...
