Sharing USB key by multiple virtual machines located at different hosts

摘要

A system for sharing a USB Key by multiple virtual machines located at different hosts including at least two virtual machine managers, each virtual machine manager including a virtual machine transceiver module which is configured to receive a request for accessing a USB Key from a virtual machine within its host; a storage module which is configured to store an association relationship between a USB Key and the virtual machine authenticated by the USB Key; a verification module which is configured to, in response to judging that the virtual machine of the received request can access the USB Key, transmit the request for accessing the USB Key to a USB Key transceiver module of a virtual machine manager of the host where the USB Key is located; and a USB Key transceiver module which is configured to receive a request for accessing a USB Key, and to transmit an access request to a connected USB Key.

主权项

1. A computer system for sharing a USB Key by a plurality of virtual machines located at different hosts, the computer system comprising:
a memory; and a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
receiving, by a first virtual machine manager located within a first host, a request for accessing a USB Key from a virtual machine within the first host, wherein an association relationship between at least one USB Key and one or more virtual machines authenticated by the at least one USB Key is stored in the first virtual machine manager; andbased on determining that the virtual machine requesting access to the USB key can access the USB Key, transmitting, by the first virtual machine manager, the request for accessing the USB Key to a second virtual machine manager of a second host where the USB Key is located, according to the stored association relationship, the second virtual machine manager configured to transmit an access request to the USB Key.
