I assume you mean that you're trying to use the upstream kernel module. If so, that won't work. From our recently added FAQ:
-=-=-=-=-=-=-=-=- Q: What features are not available in the Open vSwitch kernel datapath that ships as part of the upstream Linux kernel? A: The kernel module in upstream Linux 3.3 and later does not include the following features: - Bridge compatibility, that is, support for the ovs-brcompatd daemon that (if you enable it) lets "brctl" and other Linux bridge tools transparently work with Open vSwitch instead. We do not expect bridge compatibility to ever be available in upstream Linux. If you need bridge compatibility, use the kernel module from the Open vSwitch distribution instead of the upstream Linux kernel module. - Tunnel and patch virtual ports, that is, interfaces with type "gre", "ipsec_gre", "capwap", or "patch". It is possible to create tunnels in Linux and attach them to Open vSwitch as system devices. However, they cannot be dynamically created through the OVSDB protocol or set the tunnel ids as a flow action. Work is in progress in adding these features to the upstream Linux version of the Open vSwitch kernel module. For now, if you need these features, use the kernel module from the Open vSwitch distribution instead of the upstream Linux kernel module. -=-=-=-=-=-=-=-=- The FAQ is linked from the website and available here: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=FAQ;hb=HEAD The FAQ will be included as part of the 1.8 release. --Justin On Jun 24, 2012, at 8:12 PM, André Ruß wrote: > Hi, > > I am trying to use the brcompatd in the latest 3.4 kernel with the latest git > checkout (1.7.90). > > After starting the brcompatd the following line is posted every 5 seconds to > the syslog: > > Jun 25 02:02:37 pod1-bl1 kernel: [ 2402.712848] brcompat: timed out waiting > for userspace > Jun 25 02:02:42 pod1-bl1 kernel: [ 2407.699981] brcompat: timed out waiting > for userspace > Jun 25 02:02:47 pod1-bl1 kernel: [ 2412.687175] brcompat: timed out waiting > for userspace > > Using commands like “brctl” does work (at least addbr / delbr / addif / > delif) but they are issueing a “connection time out”: > > root@pod1-bl1:~# ovs-vsctl show > 60b13c13-0e13-44d2-8c1b-c7ca7b9c2459 > ovs_version: "1.7.0" > root@pod1-bl1:~# brctl addbr br0 > add bridge failed: Connection timed out > root@pod1-bl1:~# ovs-vsctl show > 60b13c13-0e13-44d2-8c1b-c7ca7b9c2459 > Bridge "br0" > Port "br0" > Interface "br0" > type: internal > ovs_version: "1.7.0" > root@pod1-bl1:~# brctl addif br0 eth1 > can't add eth1 to bridge br0: Connection timed out > root@pod1-bl1:~# > root@pod1-bl1:~# ovs-vsctl show > 60b13c13-0e13-44d2-8c1b-c7ca7b9c2459 > Bridge "br0" > Port "br0" > Interface "br0" > type: internal > Port "eth1" > Interface "eth1" > ovs_version: "1.7.0" > root@pod1-bl1:~# > > So brcompat is working but tools like libvirt fail since they are timeoutet. > Is there a solution for that issue? > > Regards > Andre > > _______________________________________________ > dev mailing list > dev@openvswitch.org > http://openvswitch.org/mailman/listinfo/dev _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
