Hello, I'm testing ovs command in citrix xenserver 6.0.2, and I found the following command executed when creating vlan object (with vlan tag 1000 on the eth2) in xenserver:
[root@nclcst301 debug]# ovsdb-tool show-log /etc/openvswitch/conf.db ..... record 714: 2013-12-20 17:09:02 "ovs-vsctl: /usr/bin/ovs-vsctl --timeout=20 -- --with-iface --if-exists del-port eth2 -- --may-exist add-br xenbr2 -- --may-exist add-port xenbr2 eth2 -- set Bridge xenbr2 "other-config:hwaddr=\"98:4b:e1:67:3d:ec\"" -- set Bridge xenbr2 fail_mode=standalone -- remove Bridge xenbr2 other_config disable-in-band -- br-set-external-id xenbr2 xs-network-uuids af7a9da8-ad61-52f5-3755-0fc755964e80;14c2e3a6-d154-0d23-d91d-3fcc6f100f8e;4b93be58-72f8-7867-fbe2-6d3e7fc1cf8d;4580b69a-7e78-19ae-ad5a-bad3419c3543 -- --if-exists del-br xapi10 -- --may-exist add-br xapi10 xenbr2 1000 -- br-set-external-id xapi10 xs-network-uuids af7a9da8-ad61-52f5-3755-0fc755964e80;14c2e3a6-d154-0d23-d91d-3fcc6f100f8e;4b93be58-72f8-7867-fbe2-6d3e7fc1cf8d;4580b69a-7e78-19ae-ad5a-bad3419c3543 -- set Interface xapi10 "MAC=\"98:4b:e1:67:3d:ec\""" ..... As far as I know, the above command disconnects eth2 at first (--if-exists del-port eth2) .. If it's true, can packet loss happen if other VMs are connected to the eth2 for a while? Thank you -- Jeong,Soyoung
