How to set a static UUID

Each time a VM transitions to 'Running' from a 'Powered Off' or 'Suspended' state, there is a chance the VM will be assigned to a different back-end host. When this occurs, the VM's unique identifier (UUID) will change and may cause issues with software licensing.

Setting a custom UUID

Skytap allows setting a custom UUID for a VM, which will be applied every time the VM runs, regardless of which back-end host it is assigned to. You can change this setting in the VM Settings menu, under the Hardware tab. The 'Custom UUID' must be exactly 32 hexadecimal characters (0-9, A-F, a-f), and can only be set on a VM that is 'Powered Off'. The UUID will need to be set before any software with strict licensing requirements is installed.

Automatically generate a random UUID

You can use the following URL to automatically generate a random valid UUID that can be copied and pasted in the 'Custom UUID' field in VM Settings:
