VIRTUAL MACHINE UPDATE BY MEANS OF INSERT OR SIMILAR Russian patent published in 2012 - IPC G06F15/16 

FIELD: information technologies.

SUBSTANCE: each of multiple virtual machines (VM) is stored in a suspended form in a library to be extracted from the library and restarted on a host. Each restarted VM comprises multiple software structures, every of which is at least potentially non-current and requires software update. To update a non-current VM, such a VM is extracted and restarted on a supporting host, and for each non-current structure of software there is an update permitted by obtaining a required software update from an appropriate source of updates as an insert. Alternatively, VM is installed on a computing device, components of the installed VM are studied to detect whether its every software structure is current, and each non-current software structure is updated by getting a required update of software from an appropriate source of updates as an insert and its application to the installed VM.

EFFECT: higher reliability of virtual machines update.
