1. I am using the userspace mode of ovs. When I execute the following commands to start the ovs daemon, I got one error and one warning are shown below. It looks that the ovs daemon is started and able to perform learning switch functionality. Just want to check if I can safely ignore them due to the userspace mode of ovs?
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock --remote=db:Open_vSwitch,manager_options --pidfile --detach; ovs-vsctl --no-wait init; ovs-vswitchd --pidfile --detach Jun 07 06:01:39|00001|reconnect|INFO|unix:/usr/local/var/run/openvswitch/db.sock: connecting...

The Open vSwitch kernel module is probably not loaded. Jun 07 06:01:39|00004|dpif|WARN|failed to enumerate system datapaths: No such file or directory 2. I applied the following rate limiting rules (no error is shown after executing the commands), but the rate limiting does not work. I can send 100 Mb/s traffic from one host to another. just wondering if it is because the userspace mode does not support QoS? ovs-vsctl set Interface tap0 ingress_policing_rate=1000 ovs-vsctl set Interface tap0 ingress_policing_burst=100 my topology VM1 (eth0) --- (eth0) VM2 (eth1) --- (eth0)VM3 the ovs needs to run inside VM2 for some reason of our project. The virtualization technology I used is OpenVZ, which is a OS-level virtualization. Therefore, I am not able to load any kernel module in VM, and I choose to run userspace mode of ovs. Thank you for your help. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
