METHODS AND SYSTEMS TO PERMIT MULTIPLE VIRTUAL MACHINES TO SEPARATELY CONFIGURE AND ACCESS PHYSICAL RESOURCE Russian patent published in 2015 - IPC G06F9/44 

FIELD: information technology.

SUBSTANCE: methods and systems are disclosed to permit multiple virtual machines (VM) to separately configure and access a physical resource, substantially outside of a virtual machine monitor (VMM) controlling the VM. Each of a plurality of virtual machines (VM) may access and configure a physical device through corresponding instances of a device driver which provides controllable functions of the physical device within the VM. VM-specific configuration parameters and connection information may be maintained for each of the VM, outside of a VMM, to reconfigure or virtualise the physical device for each of the VM in accordance with VM-specific configuration parameters and connection information. Physical device virtualisation augmentation features may be implemented in a combination of a physical device controller and a host device driver which executes outside of the VM.

EFFECT: high efficiency of configuring a physical device.
