Abstract
Exemplary methods, apparatuses, and systems include a first input/output (I/O) filter receiving, from a first filter module within a virtualization stack of a host computer, an input/output (I/O) request originated by a virtual machine and directed to a first virtual disk. The first I/O filter determines to redirect the I/O request to a second virtual disk and, in response, forwards the I/O request to a second I/O filter associated with the second virtual disk. The first I/O filter is a part of a first instance of a filter framework within the host computer and the second I/O filter is part of a second, separate instance of the filter framework.
