Unique ID for a Different vCenter
On one vCenter Server, the
moRef
uniquely identifies a virtual machine. If you need to track and inventory virtual machine backups across multiple vCenter Servers, you can use moRef
together with instanceUuid
. You can see the instanceUuid
at the following browser path:https://<vcserver>/mob/?moid=ServiceInstance&doPath=content.about
For direct connections to ESXi, the host address and
moRef
uniquely identify a virtual machine. However this moRef
could be different from the one that vCenter Server returns, hence the fallback to instanceUuid
. The instanceUuid
was new in VMware vSphere 4.0. In previous releases, the fallback was to Uuid
.
