Patch Set 3: Dan, I found the real reason. It is (of course!) not that the veth sides are up. When NM is running it somehow sets sysctl net.ipv6.conf.veth14.disable_ipv6=1 to any veth it manages. This affects setting of an IPv6 address only so the problem only really exists for a month or so. Do you know if we can turn some knobs to enable IPv6 in NM? I am not sure that adding [ipv6] method=auto to /etc/NetworkManager/NetworkManager.conf helps. ipv6 settings in NM: https://developer.gnome.org/NetworkManager/0.9/ref-settings.html Not even putting net.ipv6.conf.all.disable_ipv6 = 0 and net.ipv6.conf.default.disable_ipv6 = 0 to /etc/sysctl.conf (which is symlinked to .d directory, of course) and rebooting to make sure (out of pure helplessness). systctl: http://wiki.centos.org/FAQ/CentOS6 Perhaps I am doing something wrong. Maybe, maybe it's a NM bug (that it seemingly ignores my configuration). But I need to replace this old hack _now_ so I can base all my work (including fixes to DHCP and gateway reporting) on the new NM_CONTROLLED=no approach. I'll try to locate a bug if it exists and as soon as most of my fixes are merged I will sit down and file the bug if it really is there. As you asked, I prepared this text to the commit message: """ Current NetworkManager versions (certainly require this change): 0.9.9.1-35.git20140326.4dba720.el7 and 0.9.10.1-1.4.20150115git.fc21 """ -- To view, visit http://gerrit.ovirt.org/37041 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: comment Gerrit-Change-Id: Idba14753bf9cd37ec1659a49ba7e13b9478f3913 Gerrit-PatchSet: 3 Gerrit-Project: vdsm Gerrit-Branch: master Gerrit-Owner: Ondřej Svoboda <[email protected]> Gerrit-Reviewer: Dan Kenigsberg <[email protected]> Gerrit-Reviewer: Ido Barkan <[email protected]> Gerrit-Reviewer: Ondřej Svoboda <[email protected]> Gerrit-Reviewer: Petr Horáček <[email protected]> Gerrit-Reviewer: [email protected] Gerrit-Reviewer: oVirt Jenkins CI Server Gerrit-HasComments: No _______________________________________________ vdsm-patches mailing list [email protected] https://lists.fedorahosted.org/mailman/listinfo/vdsm-patches
