I use Quantum with VLAN and ip networknamespace. After update some packages, all cloud instances lost connectivity.
I run "ovs-vsctl show" and "ovs-ofctl dump-flows br-int" on both quantum-node and compute-node to check. In Quantum node, everything is ok. *root@quantum:/etc/init.d# ovs-ofctl dump-flows br-int NXST_FLOW reply (xid=0x4): cookie=0x0, duration=3284.199s, table=0, n_packets=33404, n_bytes=2134467, priority=2,in_port=156 actions=drop cookie=0x0, duration=3199.3s, table=0, n_packets=1593, n_bytes=101952, priority=3,in_port=156,dl_vlan=101 actions=mod_vlan_vid:14,NORMAL cookie=0x0, duration=3090.599s, table=0, n_packets=1539, n_bytes=98496, priority=3,in_port=156,dl_vlan=114 actions=mod_vlan_vid:23,NORMAL cookie=0x0, duration=3125.8s, table=0, n_packets=4036, n_bytes=257248, priority=3,in_port=156,dl_vlan=4 actions=mod_vlan_vid:21,NORMAL* v.v... But in compute node, all my flows disappear: *root@compute-01:~# ovs-ofctl dump-flows br-int * *NXST_FLOW reply (xid=0x4): cookie=0x0, duration=604.009s, table=0, n_packets=12897, n_bytes=823626, priority=2,in_port=1 actions=drop cookie=0x0, duration=604.591s, table=0, n_packets=0, n_bytes=0, priority=1 actions=NORMAL * I restarted nova-compute, quantum-plugin-openvswitch-agent. Also reboot compute node. But nothing can help. I checked log and did not found any error. Do you know a quick fix for situation like that? Thank you very much!
