[ovs-dev] trying to use brcompat with the latest 3.4 kernel

[André Ruß]

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 at pod1-bl1:~# ovs-vsctl show
60b13c13-0e13-44d2-8c1b-c7ca7b9c2459
    ovs_version: "1.7.0"
root at pod1-bl1:~# brctl addbr br0
add bridge failed: Connection timed out
root at pod1-bl1:~# ovs-vsctl show
60b13c13-0e13-44d2-8c1b-c7ca7b9c2459
    Bridge "br0"
        Port "br0"
            Interface "br0"
                type: internal
    ovs_version: "1.7.0"
root at pod1-bl1:~# brctl addif br0 eth1
can't add eth1 to bridge br0: Connection timed out
root at pod1-bl1:~#
root at 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 at pod1-bl1:~#

So brcompat is working but tools like libvirt fail since they are timeoutet. Is there a solution for that issue?

Regards
Andre
