CVI Hypervisor upgrades on July 5 and July 6

 
Description: 

We are planning the deployment of Microsoft patches and hotfixes on ~130 Hypervisors in the CVI service, hosting Virtual Machines in the Self-Service as well as in hostgroups dedicated to BE/CO, Engineering Services, IT/GT, EN/ICE, IT/UDS and IT/OIS.

The upgrades will take place between 07:30 and 08:00, and involve a reboot of the hypervisors. The Virtual Machines hosted on those servers will be automatically suspended into a 'Saved State', and will resume once the hypervisor has restarted (typically within 5 minutes). From the VM perspective this intervention is therefore largely transparent. The upgrade schedule is:

 Up-to-date information about which of the hypervisors host which Virtual Machine can be obtained from the VMM website (go to https://vmm.cern.ch -> "Manage my Machines" -> Click on VM name for details -> Look for "VM Host") or from the LANdb Network Database (http://network.cern.ch).
