Description:
Deployment of Microsoft patches and hotfixes on ~200 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, DG/CO, EN/ICE, IT/UDS, IT/OIS and IT/CS.
The upgrades will 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. All Virtual Machines are expected to be back by 08:30.
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).
The upgrade schedule is:
