Hi,
I have an OVS bridge br0 with no NICs and 1 vhost user port which is
connected to a VM. But ping fails between the VM and the br0 port, either way.
The stats show zero all the time. Inside the VM, tcpdump shows nothing.
This is with OVS 2.7.0 and DPDK 17.02. Please indicate what could be going
wrong.
In the host, the bridge's internal port is up.
# ip addr show br0
24: br0: <BROADCAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
qlen 500
link/ether 52:2f:57:13:d8:40 brd ff:ff:ff:ff:ff:ff
inet 200.1.1.1/24 scope global br0
valid_lft forever preferred_lft forever
In the VM, the eth interface is up with address 200.1.1.2/24.
The ports are in the following state, even after "ovs-ofctl mod-port br0 vi1
up":
# ovs-ofctl dump-ports-desc br0
OFPST_PORT_DESC reply (xid=0x2):
5(vi1): addr:00:00:00:00:00:00
config: 0
state: 0
speed: 0 Mbps now, 0 Mbps max
LOCAL(br0): addr:52:2f:57:13:d8:40
config: 0
state: 0
current: 10MB-FD COPPER
speed: 10 Mbps now, 0 Mbps max
The flows are configured as below:
# ovs-ofctl dump-flows br0
NXST_FLOW reply (xid=0x4):
cookie=0x0, duration=2833.612s, table=0, n_packets=0, n_bytes=0, idle_age=2833,

cookie=0x2, duration=2819.820s, table=0, n_packets=0, n_bytes=0, idle_age=2819,
in_port=5 actions=output:1
The table info is as below:
# ovs-ofctl dump-tables br0 | more
OFPST_TABLE reply (xid=0x2):
table 0 ("classifier"):
active=2, lookup=37, matched=28
max_entries=1000000
