Xen TEST environment

We are currently testing i386 SLC3 and SLC4 paravirtualized guests on following systems. All CERN users may login there, but please REMEMBER:

THIS IS A TEST ENVIRONMENT, NOT REGULAR SERVICE

In particular we do not guarantee this environment persistence, stability, availability or fitness for any purpose. However we are interested in your experience... (in other words: if it breaks ... keep both pieces ... and tell us about ..)

Please also bear in mind that this test system is not running on an top-performance hardware ...

  • single 160GB SCSI drive (out of which 70GB exported to guests)
  • Xen 3.0.3.0 hypervisor
  • Login restricted.
  • No AFS

Please DO NOT ASK for:

• Root access to virtual guests.
• Any access to the host system.
• Access to above systems from outside of CERN network.

If you need to test some application requiring root access in virtual environment, please followup recipes on this pages to setup your own test system.
