Abstract

The invention discloses a virtual machine starting method and device, equipment and a storage medium. The invention discloses a virtual machine starting method. The method comprises the following steps: decompressing an initramfs file in a kernel to obtain an executable file of an init process; running an executable file of the init process to create the init process; and executing the init process to finish starting. By starting the virtual machine, the initramfs file outside the kernel is prevented from being loaded, and the starting speed of the virtual machine is increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to a method, device, device and storage medium for starting a virtual machine. Background technique [0002] The initramfs file needs to be loaded during the virtual machine system startup process. The initramfs file is set outside the kernel; the external initramfs file occupies a relatively large storage space; loading the external initramfs file generally causes a delay of several seconds or more, and the startup speed of the virtual machine is slow. Contents of the invention [0003] The main purpose of the present application is to provide a method, device, device and storage medium for starting a virtual machine, so as to solve the above problems. [0004] In order to achieve the above purpose, according to one aspect of the present application, a method for starting a virtual machine is provided, including: [0005] Decompress the initramfs file in the ke...
