No, you can also use filesystem DS in combination with ssh TM for exemple. > However, configuring the storage locally on the node would allow for better > performance (especially if using SSDs), even though the VM then would not > be fault tolerant (node goes down, so does the storage for the VM).

I customized the TM (see http://blog.opennebula.org/?p=4002 ), so that image is copied from "remote" storage (could be ssh or nfs) to the local LVM. I still plan to publish these patch, even if they are based on 3.6, so I'll probably first update them so that they work on 4.x. > Is there a way to configure OpenNebula to use local logical volumes as a > datastore? Create the lv on the node, boot the VM, if nned be create the lv > on another node, migrate the VM. If you join OpenNebulaConf in Berlin, I'll give a talk about it Thursday afternoon (http://opennebulaconf.com/schedule/), I'll be happy to discuss it with you. In a nutshell, you can basically use filesystem DS with a customized version of ssh TM which creates LV on the flight.
