http://bugzilla.opensuse.org/show_bug.cgi?id=1040377 Bug ID: 1040377 Summary: [wicked] unable to add gre tunnel into ovs bridge by ifcfg files Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: thehejik@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 726043 --> http://bugzilla.opensuse.org/attachment.cgi?id=726043&action=edit wicked logs I'm trying to setup two machines, each with its own ovs-bridge containing tap devices. Those two bridges should be connected over GRE tunnel. It works like a charm when I use ovs-vsctl CLI for adding GRE into current osv bridge:

ovs-vsctl add-port br1 gre1 -- set interface gre1 type=gre options:remote_ip=10.100.51.62 (and the same command ending with "options:remote_ip=10.100.51.209" on other machine)

But problem is that when I want to create corresponding enslaved gre1 by ifcfg-gre1 file for adding GRE tunnel into ovs bridge. file ifcfg-br1:

BOOTPROTO='static' IPADDR='10.0.2.2/15' # Yes, same address for both machines STARTMODE='auto' OVS_BRIDGE='yes' OVS_BRIDGE_PORT_DEVICE_1='tap0' ... OVS_BRIDGE_PORT_DEVICE_12=tap131 OVS_BRIDGE_PORT_DEVICE_13='gre1'

file ifcfg-tap*:

BOOTPROTO='none' IPADDR='' NETMASK='' PREFIXLEN='' STARTMODE='auto' TUNNEL='tap' TUNNEL_SET_GROUP='nogroup' TUNNEL_SET_OWNER='_openqa-worker'

file ifcfg-gre1:

STARTMODE='auto' BOOTPROTO='none' TUNNEL='gre' TUNNEL_LOCAL_IPADDR='10.100.51.209' # (REMOTE and LOCAL IPs are swapped on other machine) TUNNEL_REMOTE_IPADDR='10.100.51.62' TUNNEL_TTL='64'

After performing # wicked ifup br1 the bridge is up, but there is some problem with gre tunnel and the connection to other bridge is not established.

# ovs-vsctl show Port "br1" Interface "br1" type: internal Port "gre1" Interface "gre1" error: "could not add network device gre1 to ofproto (Invalid argument)" <--- THIS IS PROBABLY THE PROBLEM Port "tap2" Interface "tap2" ... and so on

Did I miss something or the support for GRE tunnel within OVS bridge is just not implemented yet? SuSEFirewall2 is set properly, because when using ovs-vsctl then everything works.
