METHOD OF STORING VIRTUAL PORT AND MATERIAL MEDIUM MERGER Russian patent published in 2012 - IPC G06F12/08 

FIELD: information technology.

SUBSTANCE: method of storing the state of a virtual port in a virtual computer system, in which a distributed virtual port (DVport) is stored in a read-only memory cell, wherein the DVport has a given dynamic state and configuration parameters; storing the link between the DVport and VNIC for a first connection between VNIC of the corresponding virtual machine and a virtual switch associated with a first virtual port; and retrieving the state from the DVport into a new second virtual port using the dynamic state and configuration installation from the read-only memory cell when restarting the VM corresponding to the connected VNIC, restoring the state which enables the second virtual port to set up a second connection for transmitting network frames between the VNIC, corresponding to the virtual machine, and the virtual switch associated with the first virtual port, wherein the second connection is set up based on the state of the first connection.

EFFECT: ensuring correct connection between a virtual machine and a virtual port of a virtual switch, even when restarting the virtual machine.
