Virtualisation host reboot Friday 7 Feb AM virtual machines affected

The below work has now been completed and all services are back to normal. 

An issue has been identified with one of the hypervisors (virtualisation servers) which hosts a number of CEDA and JASMIN virtual machines.

A reboot of the hypervisor is needed to clear the issue but this will mean that some or all of the following virtual machines are not available for some time (hopefully a few seconds, but could be a few minutes) tomorrow morning Friday 7th Feb 2020 around 09:00.

This would result in interruptions to service(s) running on these machines.

The VMs affected are:

Many of these are not outward-facing machines but are used for components of the CEDA and JASMIN service infrastructure, so there could be some knock-on effects on services.

We apologise for any inconvenience this may cause, and thank you in advance for your cooperation.
