Description

TECHNICAL FIELD

[0001] The present application relates to the field of virtual machines, in particular to a PCIE-based on-card virtual machine system. BACKGROUND

[0002] A virtual machine (VM) refers to a complete computer system that is simulated by software, runs in a completely isolated environment, and has complete hardware system functions. Work that can be completed in a physical computer can also be implemented in a virtual machine. Each virtual machine has independent CPU, memory, hard disk, and operating system, etc., and can be operated like a physical machine.

[0003] In the past, virtual machines were run on hosts with good performance. Users directly access virtual machines on the host or indirectly access virtual machines remotely through the network. The computing resources used by virtual machines, including CPU, memory, hard disk, etc., are allocated from the host. The more virtual machines run, the fewer computing resources are left on the host, which eventually leads to a decline in host performance.

[0004] In addition, in the past, virtual machines were generally run in a virtual hardware environment with the same CPU architecture as the host. Hardware virtualization functions of the host CPU were used to accelerate the speed of virtualization. If the host wants to use heterogeneous virtual machines, it can only use software simulation and cannot use the hardware virtualization function of the host CPU, resulting in low running speed.
