Video Demo: Building a Rocks HPC Cluster with Xen Hardware Virtual Machines (HVM) (Update 1)

This is the new video demo of my Rocks HPC compute cluster after I have set dom0_mem=1024M for my Xen hypervisor.

I started all 5 nodes at one go without crashing and without sluggishness.

Previous video demo shows that I can only start 3 nodes with-out setting dom0_mem for the Xen hypervisor. If I attempt to start the 4th node, dom0 will freeze.

This is proof that setting dom0_mem really works and improves overall system performance.
