Virtualization activities in the Grid Deployment Group

Setup of a virtualization infrastructre

Within EGEE's SA3 activity a team at CERN is doing certification and testing of the gLite middleware. The usage of virtual machines significantly speeds up this process. For more information please have a look at this presentation. This project uses several tools to set up a Xen based virtualization infrastructure:

  • We take Xen rpms provided by CERN Linux support. These rpms allow us to easily integrate with the CERN SLC3/4 based Linux environment. In particular we have AFS enabled guest images. For more information look at the Linux support Xen TWiki.
  • To manage the deployment of virtual machines we use the SmartDomains, a virtual domain manager for Xen based on the open source SmartFrog framework. SmartDomains is developed at CERN openlab.
  • A web interface called vgrid was devloped on top of SmartDomains to make it easy to use.
  • To generate SLC3/4 images ready for use with Xen scripts were developed that allow to create such images easily. The scripts can be used as is or via a web interface called osfarm developed at CERN openlab.
  • Currently we have 9 servers running Xen hosting up to 33 virtual machines.

Several people are involved:
