Requesting virtual-machine changes safely
A request to change a virtual machine should identify both the new resource requirement and the effect on the application. Some changes can be made online in certain environments, while others require a restart or migration. Do not assume that every guest supports the same procedure.
Provide a complete change request
- Service and virtual-machine name, current resources, desired CPU, RAM or storage, and the reason for the change.
- Operating system and application dependencies, including any licences tied to hardware characteristics.
- Current backup status, permitted downtime and the person who will validate the application.
- A rollback plan, noting that expanding a filesystem or disk may not be easily reversible.
We will confirm the supported method, capacity and charges before proceeding. After completion, check the operating system, application, monitoring and backups. A successful hypervisor task does not by itself confirm that the application is functioning correctly.
