Description of problem:

There is no easy way to access the contents of RHEV virtual disks from a remote application. The CFME product currently accesses said data through storage LUNS directly mapped to the CFME appliance. However, this method has a number of shortcomings.

The CFME implementation of the same functionality for VMware based VMs utilizes VMware's VixDiskLib (VDDK) facility. This facility enables CFME to access the contents of VMware virtual disks remotely, via an: open, read, write, close paradigm.

A RHEVM facility simliar to VMware's VixDiskLib would enable CFME to provide comparable support for the RHEVM environment.

See:

While the full feature set is not needed, minimally open, read and close operations are required.
