Tux Machines (TM)-specific
We ended last time after configuring our first unprivileged Xen domain. In this article, we complete our cluster and then test it using an open-source parallel ray tracer. The first thing we need to do is create additional slave nodes to be used with the cluster. So, let's get down to business.
Creating Additional Unprivileged Domains
Once you have created and configured an unprivileged domain using the instructions from the previous section, you easily can duplicate this domain as described below. Start by making a backup image of the Debian_Slave1_Root filesystem. You only need to do this step once. Note that the tar command probably will take a few minutes to complete, as it is archiving an entire filesystem.
