Hi All,
I have tested ovs-vswitchd behavior with the instruction given in
INSTALL.Linux. This is working fine. In this configuration, I have two datapath
elements, br0 and br1, linked with the same ovs-vswitchd daemon.
However, now I am interested to have br0 and br1 linked with two different
ovs-vswitchd daemon. So I followed following instructions.
for br0
mkdir -p /usr/local/etc/openvswitch0
ovsdb-tool create /usr/local/etc/openvswitch0/conf.db
vswitchd/vswitch.ovsschemaovsdb-server /usr/local/etc/openvswitch0/conf.db
--remote=punix:/usr/local/var/run/openvswitch0/db.sock \
--remote=db:Open_vSwitch,manager_options \
--private-key=db:SSL,private_key \
--certificate=db:SSL,certificate \
--bootstrap-ca-cert=db:SSL,ca_cert \
--pidfile=/usr/local/var/run/openvswitch0/ovsdb-server.pid
--detach
ovs-vsctl --db unix:/usr/local/var/run/openvswitch0/db.sock --no-wait init
ovs-vsctl -db unix:/usr/local/var/run/openvswitch0/db.sock add-br br0
ovs-vsctl -db unix:/usr/local/var/run/openvswitch0/db.sock add-port br0 eth1
sudo ovs-vswitchd unix:/usr/local/var/run/openvswitch0/db.sock
--pidfile=/usr/local/var/run/openvswitch0/ovs-vswitchd.pid -v --log-file=/tmp/0
--detach
Now br0 is working fine. Also if i do ifconfig -a, br0 interface is present.
all ovs-ofctl, ovs-dpctl commands are working fine
After that I started running commands for br1 where the commands are similar to
above but i changed openvswitch0 to openvswitch1, br0 to br1 and eth1 to eth2
in above commands.
After running last command (ovs-vswitchd) for br1, br0 gets deleted
automatically. There is no interface br0 remained in the ifconfig output and
also neither of above ofctl/dpctl commands working. Now there is only br1
remained in my configuration.
I think, I am doing something wrong. Can someone suggest something in resolving
this issue which is forcing br0 to get deleted?
Thanks,
Sachin
