Abstract
The methods and systems described herein provide for granting a virtual machine exclusive access to an optical disc drive responsive to a determination the virtual machine initiated a transaction with the optical disc drive. A drive manager maps an optical disc drive connected to the computing device to a plurality of virtual machines hosted by a hypervisor executed by the computing device. The drive manager intercepts a transaction stream generated by the optical disc drive and converts the transaction stream to a command stream. The drive manager determines, based on an analysis of the command stream, a first virtual machine of the plurality of virtual machines initiated a transaction with the optical disc drive. Responsive to the determination, the drive manager locks the optical disc drive to grant the first virtual machine exclusive access to the optical disc drive.
