Hi, First of all, sorry for the rookie question. Because of my network setup my compute nodes (CentOS 7.3) are in a network segment without IPv6 routing, however IPv6 is enabled on the hosts (just the default setup in CentOS 7). This leads to problems when I try to install or update packages from the repos since some of them are already on IPv6 and the compute nodes try to access them over IPv6 and fail. I am considering disabling IPv6 on the compute nodes. Right now I am using legacy (linux bridge) networking. Will disabling IPv6 on the compute nodes prevent using IPv6 on the guest VMs?
