I'm interested to know what applications you plan to run in the VM that make disk I/O performance so important. My initial Xen installations several years ago were all to KVM partitions, but recently I've settled on file-based disk representations: * they're easy to rsync to other hosts and/or backup * i haven't noticed any significant performance difference -- Paul Heinlein <> [email protected] <> http://www.madboa.com/ _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
