Virtual machine creation method, device, device, system and computer program product

Abstract

Embodiments of the present application provide a virtual machine creation method, device, device, system and computer program product. The method for creating a virtual machine includes: obtaining a virtual machine creation request; in a physical IO device, determining a hardware queue corresponding to the virtual machine creation request; establishing a virtual machine based on the hardware queue, and determining in the Hypervisor a The corresponding virtual memory of the machine. The technical solution provided by this application realizes a virtual machine that can create a maximum number of virtual machines equal to the number of hardware queues based on multiple hardware queues in the physical IO device, with good device sharing and high deployment density; after the virtual machine is established, the Virtual memory is configured for each virtual machine in the hypervisor, so as to control the access operation of the virtual machine based on the virtual memory, so that when the client computer and the virtual machine perform data exchange, it is beneficial to improve the utilization rate of the IO device resources of the virtual machine.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a virtual machine creation method, device, device, system and computer program product. Background technique [0002] With the rapid development of science and technology, mainstream cloud computing vendors share a physical device with different tenants through IO virtualization frameworks such as virtio / vhost in order to improve the hardware resource utilization of physical IO devices (such as network cards, solid state drives, etc.) However, this solution brings serious performance loss and cannot satisfy tenants with high performance requirements. In order to meet users' requirements for high performance, the industry provides a PCI device pass-through solution, that is, a physical device is completely exposed to a tenant. Although this solution has no performance loss, one device can only be used by one tenant. , and the device slots on the physical mac...

Problems solved by technology

[0002] With the rapid development of science and technology, mainstream cloud computing vendors share a physical device with different tenants through IO virtualization frameworks such as virtio / vhost in order to improve the hardware resource utilization of physical IO devices (such as network cards, solid state drives, etc.) use, and the performance loss caused by this solution is serious, and cannot satisfy the tenants with high performance requirements

In order to meet users' requirements for high performance, the industry provides a PCI device pass-through solution, that is, a physical device is completely exposed to a tenant. Although this solution has no performance loss, one device can only be used by one tenant. , and the device slots on the physical machine are limited, which greatly reduces the deployment density and resource utilization
