Red Hat is in the KVM camp. Canonical is in the Xen camp. You'll get better support if you stay within your camp. One nice thing about KVM is that each virtual machine is a Unix process. You can "kill -9", so to speak, the entire machine. (More importantly, you can strace it, and so on). Currently they have approximately the same performance. If you need to squeeze the last bit of performance out of them then you'll have to benchmark both for your application to see which works best. On the other hand, if you are that concerned about performance then you should be using bare metal :-) By the way... there are systems that will manage large groups of KVM or Xen VMs for you. I am involved in an open source project called Ganeti which will manage clusters of either. http://code.google.com/p/ganeti Tom -- http://EverythingSysadmin.com -- my blog http://www.TomOnTime.com -- my videos _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
