Untangle 10 VMware OVF deployment fails

When I tried to deploy Untangle 10 OVF til VMware it failed: OVF Deployment Failed: File ds:///vmfs/volumes/uuid/_deviceImage-0.iso was not found Quick and dirty solution,  create a empty file (or just rename an existing ISO), rename it to «_deviceImage-0.iso» and upload it to the root of the datastore you are deploying the machine to.
