Sorry, i didn't quite understand that mail :) Okay, so far as i see it, we have three different kinds of network traffic: 1. the cluster infrastructure traffic (openais) 2. then application traffic (such as http if you're running a cluster of webservers, or nfs, or...) 3. the xm migrate traffic i think if you are able to separate the 2nd kind of traffic from the other two, the cluster should already benefit from this. and this can be done by attaching the xen-guest bridge to a different network interface then the interface that RHCS uses. unless you want to migrate every few seconds, i don't think the migration traffic should have any effects to the cluster infrastructure. best regards, johannes -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
