Bug 1614345

+++ This bug was initially created as a clone of Bug #1507587 +++

Description of problem:

related to BZ1507543, ie. trying to have ipv6 only host up.

ovsdb-server listens by default only on ipv4, not very helpful to conquer networks which must use ipv6.

see http://openvswitch.org/support/dist-docs/ovsdb-server.1.html

Version-Release number of selected component (if applicable):
ovirt-engine-setup-4.2.0-0.0.master.20171029154613.git19686f3.el7.centos.noarch

How reproducible:
100%

Steps to Reproduce:
1. have os with ipv6 address too
2. engine-setup
3. see if ovs stuff listens on ipv6 addresses as well

Actual results:
ovs stuff does not listen on ipv6

Expected results:
should listen

Hopefully this can be solved on OVS side. If RHV needs to intervene, we'd clone the bug.

Dan, Jiri,

ovsdb-server supports listening on both IPv4 and IPv6. It can be enabled by setting the listening address to '::' (IPv6 wildcard address, all zeros). In terms of configuration commands this translates to:

$ ovn-nbctl set-connection 'pssl:6641:[::]'
$ ovn-sbctl set-connection 'pssl:6642:[::]'

By default, that is if you don't specify the address, ovsdb-server listens only on IPv4. This behavior is also documented in ovsdb-server(1) man-page under the '--remote' option.

Works with OVS/OVN v2.7+.

I'm guessing you are already using 'set-connection' to enable SSL and so it would seem like a viable solution to adjust the commands to also specify the listening address.

If that does not work for you, please let me know and we'll reopen the issue.

Thanks,
Jakub
