Hi Saurav,

Currently OpenNebula can load multiple Transfer Managers, so you can choose
a different one for each host; i.e. a host could use tm_ssh and another one

You cannot use different Transfer Managers for different kind of files.
However, it should be easy to modify one of the existing drivers and detect
the kind of file to be copied, and apply different actions.

The existing LVM and NFS drivers [1] can be used as a base for this new
mixed driver. The output of the 'file' command could be parsed to detect if
the file to copy is an ISO 9660 or a bootable disk, and then apply the copy
or the LVM commands.
