Hello guys,
I'm really new to Open vSwitch but I'm pretty sure I found a bug (and if
not, I could use some help).
I already saw a thread with the exact same description:
http://openvswitch.org/pipermail/discuss/2013-January/008937.html
And the guys there say that the bridge.ko kernel module would be the
problem. I don't have a bridge kernel module installed and I still am
able to reproduce.
I am using the Ubuntu VM provided by mininet which by default comes with
ovs v1.4.3 so I purged that version and recompiled ovs v1.12.90 from
sources. After creating the dist files and installing them, I rebooted
the machine and noticed the bug:
*OVS - boot script bug*:
_Steps to reproduce_:
- fully install openvswitch v1.12.90 on a Ubuntu machine (binaries,
kernel module, boot scripts) as described in the official documents
- start all the components (ovsdb-server, openvswitch-switch,
openvswitch-controller)
- make sure it is up an running (`ovs-vsctl show` - should produce an
output containing a UUID)
- reboot the machine
- call `ovs-vsctl show` again
_Expected result_:
- the produced output should be the same as before the reboot
_Actual result_:
- the output shows a couple of errors related to /db.sock/
_Note_:
- until now we discovered that if we stop the ovsdb-server process,
delete the /db.sock/ file and relaunch ovsdb-server with all the
parameters* that should be in the init file the system will work until
the next reboot
* the following command is the one that I am using to fix ovs for the
current session. It was extracted from the official /"INSTALL" /document
in the root of the git repo:
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=db:Open_vSwitch,SSL,certificate \
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \
--pidfile --detach
If anyone else is able to reproduce this, please tell me if you know the
root cause. In the mean time I will keep you posted with what I find
(and a fix if I can get to it).
Thanks,
