[one-users] SCP bottleneck

     We've a OpenNebula 2.0 cluster  in SSH mode and when we deploy near 
simultaneously 3 or 4 MVs of about 1GB, sometimes some of the 
deployments fail because SSH/SCP connection timeouts.
     I've seen in diferent slides that is possible to make TM plugins 
based on parallel-ssh or bittorrent.

     Has anyone experimented similar problems, or developed some of 
these plugins?

Best regards
