Hello, I see a title as in subject on RH EL 7.1 release notes (and I presume the same functionality to be inside the just released, right now in respin/remirror, CentOS 7.1). Description says: The support for Remote Direct Memory Access (RDMA)-based migration has been added to libvirt. As a result, it is now possible to use the new rdma:// migration URI to request migration over RDMA, which allows for significantly shorter live migration of large guests. Note that prior to using RDMA-based migration, RDMA has to be configured and libvirt has to be set up to use it. What about enabling into oVirt too, via os support detection or something similar? Eventually in 3.6 and not in 3.5 trunk. I didn't delve yet with it and its configuration, but I think it could be a nice thing for oVirt. Gianluca
