The key to *keeping* it off in RHEL 6, and I assume in CentOS 6, is the setting NM_CONTROLLED="no" in the /etc/sysconfig/network-scripts/ifcfg-* files. This is a new setting in RHEL 6, and I'm having difficulty finding documentation for it, but it seems to work in keeping NetworkManager's greedy little paws off my stable settings.
In both the RH and FP docs, the only reference that I've found is in this section: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualiza...
Yeah, "libvirt" is not your friend for network configurations, nor is the "bridged" network setup used for KVM. It's not well supported, especially in the documentation.
RHEL 5 has a similar section so it's not a new setting, just a not-well-documented one (like a DNS or DHCP one that you referred to recently).
libvirt is also not your friend for correct documentation. This *will not work* for RHEL 5 or CentOS 5, because there is nothing in the actual /etc/sysconfig/network-scripts to support it. You have to disable NetworkManager with chkconfig or rip it out, which is actually safer.
