Patent attributes
An on-demand disposable virtual work system that includes: a virtual machine monitor to host virtual machines, a virtual machine pool manager, a host operating system, a host program permissions list, and a request handler module. The virtual machine pool manager manages virtual machine resources. The host operating system interfaces with a user and virtual machines created with an image of a reference operating system. The host program permissions list may be a black list and/or a white list used to indicate allowable programs. The request handler module allows execution of the program if the program is allowable. If the program is not allowable, the host request handler module: denies program execution and urges a virtual machine specified by the virtual machine pool manager to execute the program. The virtual machine is terminated when the program closes.
