- Sandia supercomputer boots a million virtual machines. Computer scientists at the Energy Department's Sandia National Laboratories have simultaneously booted one million Linux kernels, all of which ran as virtual machines on the labs' Thunderbird supercomputer.
- Thunderbird is a 4,480-node Dell-based computer cluster. Each node ran 250 Linux kernels. The host OS on each node is a stripped-down version of Linux kernel, compiled by the researchers themselves. It contains only the kernel core and and a start-up script that boots up the virtual machines. "...The root file system lives out in Random Access Memory..."
- For the virtualization, the system uses a hypervisor built into the Linux kernel, called Lguest, which was developed by the research arm of IBM. ...it is "very fast and very lightweight,"...the start-up for each virtual machine is a fraction of second..."
- The management software is OneSis, which was originally developed by Sandia. "...OneSis is pretty key to making this thing work at all. It is good at managing thousands of thousands of nodes in a very easy way..."
