According to wanghui's comment, this issue was fixed in version: rhev-hypervisor6-6.5-20131017.0.iso ovirt-node-3.0.1-4.el6.noarch but the item of Netconsole server address still could accept ipv6 address in version: ovirt-node-iso-3.0.3-1.1.fc19.iso ovirt-node-3.0.3-1.fc19.noarch
While submitted upstream, it doesn't appear to have been pulled back into the node 3.0 branch. I now submitted it there as well.
This is an automated message. Re-targeting all non-blocker bugs still open on 3.4.0 to 3.4.1.
