Most probably you forgot to share the memory between host and guest. in the VM xml: E.g.: <memoryBacking> <hugepages> <page size='2' unit='M' nodeset='0'/> </hugepages> </memoryBacking> ... <numa> <cell id='0' cpus='0-1' memory='4194304' unit='KiB' memAccess='shared'/> </numa> ... fbl > Compute0: > Bridge br-int > Controller "tcp:127.0.0.1:6633" > is_connected: true > fail_mode: secure > Port "vhu2aae3928-3c" > tag: 1 > Interface "vhu2aae3928-3c" > type: dpdkvhostuser > root@compute0:~# file /var/run/openvswitch/vhu2aae3928-3c > /var/run/openvswitch/vhu2aae3928-3c: socket > > Compute1: > Bridge br-int > Controller "tcp:127.0.0.1:6633" > is_connected: true > fail_mode: secure > Port "vhuca25b420-6d" > tag: 1 > Interface "vhuca25b420-6d" > type: dpdkvhostuser > root@compute1:~# file /var/run/openvswitch/vhuca25b420-6d > /var/run/openvswitch/vhuca25b420-6d: socket > > > When I ping, I even does not find ARP packets in the br-int flow tables. > root@compute0:~# ovs-ofctl dump-flows br-int | grep "in_port=3" > cookie=0xb177d87a58ae18fe, duration=1927.889s, table=0, n_packets=0, > n_bytes=0, idle_age=1927, priority=10,icmp6,in_port=3,icmp_type=136 > actions=resubmit(,24) > cookie=0xb177d87a58ae18fe, duration=1927.886s, table=0, n_packets=0, > n_bytes=0, idle_age=1927, priority=10,arp,in_port=3 actions=resubmit(,24) > cookie=0xb177d87a58ae18fe, duration=1927.893s, table=0, n_packets=0, > n_bytes=0, idle_age=1927, priority=9,in_port=3 actions=resubmit(,25) > cookie=0xb177d87a58ae18fe, duration=1927.891s, table=24, n_packets=0, > n_bytes=0, idle_age=1927, > priority=2,icmp6,in_port=3,icmp_type=136,nd_target=fe80::f816:3eff:fed3:2116 > actions=NORMAL > cookie=0xb177d87a58ae18fe, duration=1927.888s, table=24, n_packets=0, > n_bytes=0, idle_age=1927, priority=2,arp,in_port=3,arp_spa=192.168.100.13 > actions=resubmit(,25) > cookie=0xb177d87a58ae18fe, duration=1927.896s, table=25, n_packets=0, > n_bytes=0, idle_age=1927, priority=2,in_port=3,dl_src=fa:16:3e:d3:21:16 > actions=NORMAL > > root@compute0:~# ovs-ofctl show br-int > OFPT_FEATURES_REPLY (xid=0x2): dpid:0000caf6709a034a > n_tables:254, n_buffers:256 > capabilities: FLOW_STATS TABLE_STATS PORT_STATS QUEUE_STATS ARP_MATCH_IP > actions: output enqueue set_vlan_vid set_vlan_pcp strip_vlan mod_dl_src > mod_dl_dst mod_nw_src mod_nw_dst mod_nw_tos mod_tp_src mod_tp_dst > 1(int-br0): addr:7e:de:e2:7b:2a:83 > config: 0 > state: 0 > speed: 0 Mbps now, 0 Mbps max > 2(patch-tun): addr:5a:2a:d3:f0:14:72 > config: 0 > state: 0 > speed: 0 Mbps now, 0 Mbps max > 3(vhu2aae3928-3c): addr:00:00:00:00:00:00 > config: 0 > state: 0 > speed: 0 Mbps now, 0 Mbps max > > Best Regards > Xu Rongjie (Max) > -- Flavio _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
