Operating system starting method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides an operating system starting method and device, electronic equipment and a storage medium. After Xen Hypervisor initialization is completed, a privileged domain Dom0 is started; the first virtual machine DomU and the second virtual machine DomU are started through the privilege domain Dom0, a first display card of the electronic equipment is directly connected to the first virtual machine DomU, and a second display card of the electronic equipment is directly connected to the second virtual machine DomU; the operating systems are started in the at least two LXC software containers corresponding to the target virtual machine, the target virtual machine comprises a first virtual machine DomU and/or a second virtual machine DomU, and the operating systems corresponding to the at least two LXC software containers share a display card corresponding to the target virtual machine. According to the method, two virtualization technologies are combined, and the at least two operating systems are started in the at least one virtual machine, so that all the operating systems can be started when the number of the graphics cards is smaller than the number of the started operating systems.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an operating system startup method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of Internet technology, the requirements for the corresponding operating system are higher, especially for the automotive industry. Under the premise of ensuring the stable operation of the vehicle, the modern intelligent cockpit system puts forward new requirements for the display of vehicle instrument information, entertainment information, etc., and the start-up and operation of multiple systems. Because there are functional differences between different operating systems, different operations provide different requirements for isolation and synchronization of system checks. [0003] Currently, Hypervisor technology is mainly used to start multiple operating systems. Hypervisor technology can isolate the kernels of...

Problems solved by technology

[0004] When the number of graphics cards on the device is less than the number of operating systems that need to be started, Hypervisor technology can allow the operating system to exclusively enjoy the right to use the graphics card through the graphics card pass-through method. However, some operating systems may not have the right to use the graphics card, resulting in some operating systems Can't start problem

Or, the paravirtualization (Para virtualization, referred to as PV) type provided by the Hypervisor technology enables the virtualization of the graphics card, but this method is difficult to implement in the Xen Hypervisor, and the stability of the operation of the subsequent operating system is poor
