On-card virtual machine system based on PCIE

Abstract

The invention provides an on-card virtual machine system based on PCIE (Peripheral Component Interface Express), which comprises a host and at least one PCIE card inserted into a PCIE card slot of the host, an on-card virtualization management system runs in the PCIE card, and a host virtualization management system client and a plurality of virtual machine clients run in the host; the on-card virtualization management system creates a plurality of virtual machines by utilizing resources such as a CPU (Central Processing Unit), a memory and a flash memory on the card; the host virtualization management system client is connected with the on-card virtualization management system through a PCIE (Peripheral Component Interface Express) interface so as to create and manage a virtual machine and the like in each PCIE card; and the virtual machine client is connected to a plurality of virtual machines created by the on-card virtualization management system through PCIE (Peripheral Component Interface Express) interfaces, and receives data such as pictures and audios in the virtual machines through the PCIE interfaces. According to the method, the operating system is operated by using resources such as the CPU, the memory and the flash memory on the independent PCIE card to support the virtualization system, calculation resources of a host are not used, the performance of the host is not reduced, and a plurality of PCIE cards can be inserted to increase the number of virtual machines.

Description

technical field [0001] The invention relates to the field of virtual machines, in particular to a PCIE-based on-card virtual machine system. Background technique [0002] A virtual machine (VM, 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. Everything that can be done on a physical computer can be done on a virtual machine. Each virtual machine has independent CPU, memory, hard disk and operating system, etc., and the virtual machine can be operated like a physical machine. [0003] In the past, virtual machines were running on hosts with better performance. Users directly accessed virtual machines on the hosts, or indirectly accessed virtual machines remotely through the network. The computing resources used by the virtual machine, including CPU, memory, hard disk, etc., are all allocated from the host; the more virtual machines are running, the l...

AI Technical Summary

Problems solved by technology

If the host wants to use a heterogeneous virtual machine, it can only be simulated by software, and the hardware virtualization function of the host CPU cannot be used, resulting in slow running speed
