Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] refer to figure 1 , figure 1 It is a flowchart of an embodiment of a method for establishing a virtual machine shared storage cache in the present invention, including:

[0025] Step S101: Obtain the data read and written from the virtual boot disk during the boot process of the virtual machine.

[0026] A virtual machine refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment.

[0027] When the virtual machine is started, the virtual machine reads and writes data from the virtual boot disk. These data are the real and valid data needed for the virtual machine to start, and these valid data are obtained to facilitate storage of these virtual machines. Read and write from the virtual boot disk when the virtual machine starts The data.

Abstract

The present invention discloses a method and device that establishes a virtual machine sharing storage cache. This method includes: data read and write from the virtual startup disk during the start of the virtual machine; store the data described to the virtual machine shared cache device for other for othersRead the data from the virtual machine sharing buffer device when starting the virtual machine.In the above method, the present invention can solve the input and output problem when the virtual machine concurrently starts with the effective data of the virtual machine with a small memory space.

Description

technical field [0001] The invention relates to the technical field of virtual machines, in particular to a method and device for establishing a virtual machine shared storage cache. Background technique [0002] Regardless of whether it is a virtual machine deployed in full-clone mode or a virtual machine deployed in linked-clone mode, when a large number of virtual machines are started at the same time, frequent input and output (IO, Input Output) operations occur, which creates a negative impact on shared storage. The high input and output per second (IOPS, Input Output per second) pressure peak causes the virtual machine to start slowly. When configuring desktop cloud storage, configure it according to the highest peak requirement, resulting in waste of high IOPS storage configuration during normal hours. [0003] The existing technology adopts the flow control method, sets the start time of the virtual machine several hours before going to work, and gradually starts al...
