PARALLELIZED VIRTUAL MACHINE CONFIGURATION

摘要

Techniques for facilitating parallelized configuration of multiple virtual machines. The techniques include duplicating commands received from an administrator and controlling the multiple virtual machines with those commands in a parallel manner. Different types of commands are treated differently. More specifically, commands for controlling software executing in the virtual machines are replicated and sent to each virtual machine. By contrast, commands for managing virtual machines themselves are provided to virtualization software like a hypervisor to be executed. Duplication of the commands for controlling software executing in the virtual machines is performed by an input/output multiplexer, which also has the function of combining display output from each of the virtual machines. More specifically, the input/output multiplexer displays a common display output to the administrator, where the common display output is the screen that is shown on each of the virtual machines.

主权项

1. A method for parallelizing execution of configuration operations for a plurality of virtual machines, the method comprising:
identifying a first command for the plurality of virtual machines; determining that the first command comprises an input/output command for execution by each virtual machine in the plurality of virtual machines; replicating the first command for each of the virtual machines in the plurality of virtual machines to generate first replicated commands; and controlling each virtual machine of the plurality of virtual machines according to the first replicated commands via an input/output multiplexer.
