This patch contains the implementation Daniel Berrange did of storage pools using SCSI HBAs. I have updated it for the current tree in preparation for implementing NPIV support. Let me know what you think. This looks like a great addition but I wonder if it is of any real use without supporting multipath? On SANs issuing I/O to some paths might cause severe performance penalties or the LUN might be visible but I/O is rejected until an explicit switch over command is sent. This would be handled transparently if multipath would be used on top. Any plans to add this? (Otherwise I might give this a try once I'll find some more free time to spend on libvirt again).
Funny you should mention multipath, that's what I'm working on at the moment. :) The host code will also provide a basis for NPIV support. Dave
