[wildfly-dev] IPv6 testing changes

Hi guys, JGroups update <https://github.com/wildfly/wildfly/pull/6805> exposed a problem with our ipv6 testing on our CI. To fix that we had to modify the network configuration on all build agents and config how ipv6 testsuite is ran. As part of work we also simplified testing on ipv6 where now all you need to pass to testsuite is -Dipv6. for anyone of you that runs ipv6 testsuite locally on linux add this config for your network: # Allow loopback to multicast ip -6 route add table local local ff13::/16 dev lo metric 5 # Add an additional "unique" address to lo for clustering tests ifconfig lo add fccc::2/128 Anyone that has currently open PR that is not merged yet, to rebase them as otherwise you will get clustering & domain ipv6 related test failures. -- tomaz
