It had me a bit confused, as I distinctly recall disabling all IPv6 support while building the machine.
Anyhow, since I don't need IPv6 support at the moment and to avoid any unnecessary red flags while booting, I'll just go ahead and disable it completely.
0. Login as root / su
1. Check to see if it loads on boot.
chkconfig --list | grep ip6tables
//in my instance, it was enabled for levels 2,3,4 and 5;
2. Disable ip6tables
chkconfig ip6tables off
3. Stop ip6tables service (if running)
service ip6tables status (if process is runnig, stop; if not, ignore next line)
service ip6tables stop
That's it!
It may or may not help my VM hanging issue, but at least it'd clear that pesky red flag.
Cheers,
noveck
