Support non-"dir" storage pools for libvirt

[jas4711]

Am I right in understanding that oz only supports libvirt 'dir' storage pools? I can't seem to find any way to use other storage pools for creating my virtual machines, and the "dir" pool type appears to be hard-coded in oz/Guest.py.

If my understand is correct, please allow me to request that Oz supports other storage pools, so that I can create virtual machine directly onto a LVM logical volume. I suppose some new TDL keywords are needed for this.

Yeah, it's true that it is currently hard-coded. I've never had a feature request before for anything else, so I've never looked into anything else :). It's definitely possible, it would just need some work. I'll put it on the TODO list.
