Abstract
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.
