Isn't the rhel way to install NetworkManager anyway? Because then you can forget all your ifcfg scripts anyway because they will be overwritten by NM.
At least that was the cause when i had NetworkManager installed... (That was why i removed it if i remember correctly)
Does anyone have a good link on that subject?
IBM says that tap interfaces are best practice:

My RHCSA course material doesn't even touch the subject (At least not until now). The Red Had documentation is only focused on using virt-manager and thereby explains not much in that regards.
