Additional IP addresses

Affects OpenNebula 6.0.0.2

OpenNebula has a bug whereby secondary IP addresses have no network connectivity due to a bug in how the IPTables rules work.

This affects IPv4 and IPv6, but we only care about IPv4 here.

When a VPS goes up, multiple new iptables chains are created. All are correct, apart from the base chain which needs all secondary IP addresses added to the final ipset list.

If the VPS ID is 34, find the list of IPs being checked by typing ipset list one-34-0-ip-spoofing and confirm that just the primary IP address is there.

Add all the additional IP addresses using the command ipset add one-34-0-ip-spoofing <IP address>
