Title: COMMUNICATIONS PORT PASSTHROUGH METHOD AND DEVICE
Abstract:
A communications port passthrough method and device, the method comprising: when passing through to a virtual machine a first communications port of a host machine, providing first port information of the first communications port (S11); obtaining port information of every communications port of the host machine (S12); determining second port information from among the port information of every communications port of the host machine, matching the first port information (S13); passing through to a virtual machine a second communications port, which corresponds to the second port information (S14). The present solution can automatically pass through a second communications port of a cascade device of a first communications port through to a virtual machine when the first communications port has already been passed through to a virtual machine.
