Problems solved by technology

[0013] Although the device allocation method under the existing virtualization technology also selects the corresponding mode of accessing the physical device according to the specific situation, but in the direct access to the physical device mode, the user virtual machine directly accesses the physical device without being managed by the virtual machine manager. to visit
In addition, the device allocation methods under the existing virtualization technology are all aimed at the situation where a single user virtual machine accesses the physical device, and the use right of the physical device is always controlled by the single user virtual machine

Abstract

The invention discloses a method for dynamically allocating apparatuses, an apparatus access monitoring unit in the method monitors an access physical apparatus of user virtual machine, an apparatus access mode controlling unit determines the access mode of the access physical apparatus of user virtual machine according to the information obtained by monitor, and then automatically converts the access mode into the determined access mode. At the same time, the invention also discloses a device for dynamically allocating apparatuses, comprising an user virtual machine, an input output management virtual machine, a virtual machine manager, system hardware and a virtual machine manager, and further comprising the apparatus access monitoring unit and the apparatus access mode controlling unit. Considering two aspects of performance and share, the invention automatically allocates the apparatuses for the user virtual machine according to the access request sent by the user virtual machine to the apparatuses and the using condition of the current physical apparatus, such that the limited physical apparatus can be used by a plurality of virtual machines and guarantee the excellent performance of the apparatus in the virtual machines.

Description

technical field [0001] The invention relates to a method for allocating computer equipment, in particular to a method and device for dynamically allocating equipment based on virtualization technology. Background technique [0002] Existing virtual machine systems are generally divided into two types, one is a virtual machine system that includes an input-output management virtual machine, and the other is a virtual machine system that does not include an input-output management virtual machine. [0003] figure 1 A virtual machine system structure diagram not including the input and output management virtual machine is given. The figure includes a first user virtual machine 101, a second user virtual machine 102, a third user virtual machine 103, a virtual machine manager 104, and system hardware 105, wherein the first user virtual machine 101 includes a first device driver module 1011, and The second user virtual machine 102 includes a second device driver module 1021 , t...
