Question: I'm upgrading to a newer version of OnApp and I need to enable IPV6 on my CentOS 5 HVs. How do I do this?
Answer: To enable IPv6 support do the following:
1. Edit /etc/modprobe.conf and comment strings:
alias ipv6 off
options ipv6 disable=1
2. Edit /etc/sysconfig/network
replace NETWORKING_IPV6=no with NETWORKING_IPV6=yes
3. Reboot the HV
