High availability method and architecture of universal serial bus (USB) peripherals in virtualization environment

Abstract

The invention discloses a high availability method of universal serial bus (USB) peripherals in a virtualization environment. The high availability method of the USB peripherals in the virtualization environment comprises following steps that a redirection system device and a server are connected to the same network; each USB peripheral is connected to the redirection system device, and a destination address for redirection of each USB peripheral is configured on the redirection system device; the redirection system device directs the inserted USB peripherals to corresponding virtual machines according to the configured destination addresses for redirection; and when the server, in which the virtual machines are, breaks down, the virtual machines are migrated to another server from the server breaking down, the redirection system device redirects the USB peripherals to the migrated virtual machines, and the virtual machines continue to run a function or a service authenticated or authorized by the USB peripherals. The high availability of the migrated virtual machines and the function or service thereof is guaranteed.

Description

technical field [0001] The invention relates to an application technology of a USB peripheral in a virtualized environment, in particular to a high-availability method for a USB peripheral in a virtualized environment. Background technique [0002] Driven by the advancement of science and technology, network technology is increasingly developed, and the demand for servers is also increasing. In order to save IT hardware costs and improve server utilization, virtualization technology is becoming more and more popular. Virtualization English translation is Virtualization, which is widely used in the IT industry , virtualization refers to the use of various methods to simulate various hardware resources (including CPU, RAM, hard disk, and network controller) of a physical computer, so as to realize that multiple "real" computers can run on a single physical computer. Based on the virtual machine technology, each virtual machine can run its own independent operating system witho...

Problems solved by technology

[0004] When the virtual machine function or service does not require authentication or authorization, the migration of the virtual machine will not affect the function or service. Due to copyright protection and other factors, when some functions need to use USBKey for authentication or authorization, only the USBKey needs to be inserted. The relevant functions or services can only work normally on the server running the virtual machine. When the server fails to provide services, the virtual machine will be migrated to other servers. To ensure the operation of these services, the USBKey must also be migrated accordingly. On the hypervisor system of server virtualization, and then use the USBPass-through function of the virtualization platform to penetrate the USB peripherals into the corresponding virtual machines. During this process, the USB peripherals do not automatically follow the migration of the virtual machines, but need to Physical migration to solve, which results in high availability of virtual machines, but running functions or services are not highly available, it still needs to be solved technically
