[Libvir] Proposal for the storage API (for discussion only)

[Richard W.M. Jones]

This is an outline for the storage API, for discussion only.  It is 
mostly unimplemented, but presented as a kind of "literate patch", so 
you can read the API calls and how they could be implemented.

I've tried to follow as far as possible operations which are needed in 
order to make virt-install / virt-manager work in the remote case, and 
also to support discovery and creation of partitions / LVs / iSCSI LUNs.

The new API calls are:

   virStorageFileLocations
	- returns a list of locations which can be used
	  for creating file-backed guests

   virStorageFileStat
   virStorageFileStatVFS
   virStorageCreateFile
	- for creating file-backed guest storage

   virStorageListGroups
   virStorageCreateVolume
	- for discovering and creating partitions, LVs, LUNs, &c.

Rich.
