Hi,
Just to up my problem, I always need help.
Do you think it could be a driver incompatibility ?
I remember, I already do that conf a year ago. I used other hardware
with drivers r8169, e1000e and tg3 (only 2 of them but I don't
remember which ones).
Here my OVS setup:
# modprobe openvswitch_mod.ko
# ovsdb-tool create /etc/openvswitch/conf.db
/usr/share/openvswitch/vswitch.ovsschema
# ovsdb-server /usr/local/etc/ovs-vswitchd.conf.db \
--remote=punix:/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,managers \
--private-key=db:SSL,private_key \
--certificate=db:SSL,certificate \
--bootstrap-ca-cert=db:SSL,ca_cert \
--pidfile --detach
# ovs-vsctl --no-wait init
# ovs-vswitchd unix:/var/run/openvswitch/db.sock \
--pidfile --detach
I check log and I cannot see anything. Can I start OVS more verbosely ?
