You and Osier should talk about exactly what you're doing and how to implement it. Does tmpfs fit the requirements? Then it could just be a <pool type='filesystem'/> with <source device='tmpfs'/> or something like that. (In reply to comment #2) > Does tmpfs fit the requirements? Then it could just be a <pool > type='filesystem'/> with <source device='tmpfs'/> or something like that. tmpfs might work. I don't know the performance differences between scsi_debug direct, LVM on top of scsi_debug, or qcow like images on top of tmpfs. One thing that libvirt would have to do is recreate the setup each start up. It's not enough to just make the tmpfs pool, it would need to recreate any image files on top of it. People can do this manually with host tmpfs mounts... I think that's sufficient without needing to add native libvirt support |
