Abstract:
1. A computer implemented method for mapping a Virtual machine (VM) drive to underlying storage, the method comprising: locating a signature for a physical disk mounted to a VM, the signature to the physical disk being assigned by an operating system; creating a snapshot of the physical disk to the VM while the VM is in operation; querying the snapshot of the physical disk in read-only mode for the signature; finding a signature associated with at least one or more files on a storage medium representing a virtual machine file system (VMFS) for a hypervisor that is running the VM; finding a portion of the at least one or more files on the storage medium that contains the signature; comparing the signature of the snapshot of the physical disk with the signature associated with at least one or more files on the storage medium until a common signature is found; and
