Description

There's a section of code in vmware.pm which deletes unused VM files if additional space is need for a reservation. It currently checks if the VM files already existing on the host server have a corresponding VM that is turned on. This doesn't necessarily mean the VM is being used by a VCL reservation. It's possible for unused VMs to be on and the the VCL process won't be able to make enough space available.

Another enhancement would be to delete unused VM files in order of image popularity or to delete files for images which are already loaded on another VM host.
