I understand that Citrix ships a vlan-maint release with 6.0.2, but I also know that some users at least used to install newer OVS on top of it. If that is still an important use case, then I'd like to continue supporting it. I'm going to ask around and see if anyone around here knows of that still going on. > My intention, of removing --fake-iface from > rhel/etc_sysconfig_ifup-ovs is, if rhel doesn't want a fake bond > interface why should it create one. --fake-iface was created for > compatibility reasons and should only be used if it is required to. I agree that removing --fake-iface from rhel/* is a separate issue, that doesn't have to be tied to removing it globally (which really I'd like to do, I'm just worried about break compatibility). _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
