Add single stack ipv6 unit tests to masquerade. Signed-off-by: Alona Kaplan <alkaplan@redhat.com>
Skip ipv4 tests for cluster with no ipv4. Skip ipv6 tests for cluster with no ipv6. Skip dual stack test for cluster that doesn't support both ipv4 and ipv6. Signed-off-by: Alona Kaplan <alkaplan@redhat.com>
Skip tests that are not supported until RA is introduced - issue- kubevirt#7184 Signed-off-by: Alona Kaplan <alkaplan@redhat.com>
skip-dual-stack-test flag shoud be true in single stack ipv6 cluster. Signed-off-by: Alona Kaplan <alkaplan@redhat.com>
The login is taking a bit longer since discovering ipv4 address fails and it takes a ~minute until the discovery gives up. Using cloud-init-nocloud userdata to turn off dhcp on eth0 interface doesn't help to solve the issue since the usedata is invoked after the networking. cloudinit NetworkData or metadata.network-interfaces doesn't help as well, since it is not properly working on cirros. This is a temporary solution. A follow-up solution will be to use alpine instead of cirros. Signed-off-by: Alona Kaplan <alkaplan@redhat.com>
Till now, our tests assumes ipv4 is always supported. Now that we support single stack ipv6 this assumption is wrong. This commit fixes the tests to run ipv4 tests only if ipv4 is supported by the cluster. Signed-off-by: Alona Kaplan <alkaplan@redhat.com>
Change the tests to test both ipv4 and ipv6. Skip the ipv6 tests since VM port-forwarding over ipv6 is not supported yet. Tracking issue kubevirt#7276 Signed-off-by: Alona Kaplan <alkaplan@redhat.com>

ipv6 support is in alpha stage on Istio u/s and is not supported yet by kubevirt. Note: even once ipv6 will be fully supported by istio, kubevirt may have troubles to make it work for VMs because there is no IPv6 equialent to "sysctl net.ipv4.conf.all.route_localnet".
