Start by reproducing the VMware deployment with salt-cloud -m %mapname% using the supplied Ubuntu template and compare it with the working RHEL 7 case. Trace the salt-cloud VMware provisioning path to determine where the hostname is handled; done means the deployed Ubuntu guest reports the requested hostname instead of ubuntu.
