Re: [Libvir] Storage manager initial requirements and thoughts

Experiance with developing virt-inst, virt-manager & cobbler/koan has shown that we need a simple API for enumerating available storage volumes, and allocating new volumes. In providing such an API though, we don't want to have to mandate that everyone using libvirt also install Conga. While Conga is indeed a very capable tool, requiring install / setup of another web service is going to put up a singificant barrier to entry for people wanting to use libvirt/ Particularly for developers who are just experimenting with virtualization on a laptop / desktop / couple of machines. Hence our initial goal is to find a suitable C library we can call into to perform our simple set of storage management tasks. Now in keeping with the libvirt model of pluggable hypervisor drivers, I'd expect the underlying libvirt impl of any storage APIs to also be pluggable. So while the initial impl might be based on GParteD, we would have the option of also providing a Conga based backend at a later date.
