Abstract

The invention provides an analog input output method, a device and a system of virtual machine cluster. The analog input output method, the device and the system of the virtual machine cluster is suitable for the technical field of virtual machines. The analog input output method, the device and the system of the virtual machine cluster comprises that first servers receive analog input / output (I/O) processing instructions of a second server; the second server integrates all device models (DM) of virtual machines (VM) in a VM cluster; the I/O processing instructions are generated by the DMs; the first servers renew virtualization states of the VMs according to the analog I/O processing instructions, wherein the virtualization states of the VMs are instructed by the analog I/O processing instructions. In embodiments of the analog input output method, the device and the system of the virtual machine cluster, the communication between the servers of each VM and the server of each DM can be achieved by intensively operating the DMs of all VMs of the VM cluster on one server and utilizing a non-transparent bridge (NTB) mechanism of a peripheral component interconnect express (PCIE) or a remote direct memory access (RDMA). The analog I/O of the VM can be achieved and software architecture of the VM cluster is simplified efficiently. Using rate of the VM cluster resource can be improved.

Description

technical field [0001] The invention belongs to the technical field of virtual machines, and in particular relates to a virtual machine (Virtual Machine, VM) cluster simulation input / output (Input / Output, I / O) method, device and system. Background technique [0002] Virtual I / O Server (Virtual I / O Server, VIOS) is a device used to provide shared I / O services and simulated I / O services for VMs in a virtualization system, which serves as the bottom layer of the current popular cloud computing platform One of the important supporting technologies directly affects the I / O performance of the VM, and the complexity of its implementation architecture will directly affect the complexity of the entire virtualization system. [0003] In a large-scale data processing environment such as a cloud computing center, a cluster composed of multiple servers, network devices, and storage devices is running, and by deploying virtualization software on the server, the entire cluster can create t...
