Nope, only specific licensing software seem to be checking this

We put in serial either
1. the UUID Engine send to us
2. the host UUID as returned by our getHostUUID utility function
the latter is unlikely to change, even after this disk move.
depends on which host the VM is started. It’s the host-derived ID so it’s often different
every time you run a VM.
So I suppose here it just means the VM was launched on a different host. It shouldn’t be
significant to the boot issue.
So the first suspect in line is Engine
Arik, do you know if Engine is indeed supposed to change the UUID in this flow?
That seems very surprising.
Thanks and bests,
