Is private cloud virtualization platform privacy-friendly as a potential solution?

Is that a good idea if I set up whonix vms on ovirt, openstack or red hat virtualization(RHV) on a rack server and use/manage it remotely from webui, ssh or rdp? Is there any potential negative side compare with install on a pc environment? Thanks!
