Further, do I need tun/tap to host VMs that themselves support virtual ips? The module for tun I found as part of the base install. But I cannot locate the module for ethertap and yum does not tell me where it is found.
Yep, you do want tun/tap. But if you create a regular bridge and tells virt-manager or libvirt to use this for your virtual machines, virt-manager/libvirt will take care of the tun/tap setup.
From your virtual machines point of view, tun/tap will get you the
same connectivity as if you plugged a ethernet cable from your network into it, without any restrictions.
