Thanks, that helps. What the engine isn't finding is the user, not the
virtual machine. Can you provide more information about that user? I
mean, take the virtual machine and find via the GUI which user is using
it. Then go to https://.../ovirt-engine/api/users and find that user.
Share the definition of that user that you get there, if possible.
