[ovs-discuss] upgrade/downgrade issue between openvswitch 1.1.0pre and 1.4.1

[YIMIN CHEN]

Hi,

I am working on openvswitch 1.1.0pre, and would like to upgrade to
1.4.1. I have two source trees, one for each version. What is the
right way to do if I want to switch back and forward with two
versions? I reran "make;make install" and then restart the servers, is
that correct?

 I installed 1.4.1 from one source tree and then try to use 1.1.0pre
in an older tree, which was previously working. The issue I am seeing
now is the output of ovs-ofctl seems wrong:

it used to be:

  cookie=0x0, duration_sec=1618s, duration_nsec=206000000ns,
table_id=1, priority=32768, n_packets=0, n_bytes=0,
idle_timeout=10000,hard_timeout=28270,ip,nw_dst=11.1.1.4,actions=mod_dl_dst:00:aa:bb:00:00:01,output:2
  cookie=0x0, duration_sec=1618s, duration_nsec=206000000ns,
table_id=1, priority=32768, n_packets=0, n_bytes=0,
idle_timeout=10000,hard_timeout=65407,ip,,nw_dst=11.1.1.5,actions=mod_dl_dst:00:aa:bb:00:00:02,output:3

Now it becomes:
stats_reply (xid=0x712bf): flags=none type=1(flow)
  cookie=0x0, duration_sec=28s, duration_nsec=193000000ns, table_id=1,
priority=32768, n_packets=0, n_bytes=0,
idle_timeout=10000,tun_id_wild,actions=mod_dl_dst:00:aa:bb:00:00:02,output:3

1) two flow entries become only one,
2) even the one flow entry does not look the same.

Of course now my hosts can not ping each other.
I haven't change any code, the only thing I can think of is I did
something wrong during upgrade/downgrade.

I really appreciate if you can give me some advise on what I did wrong.


Thanks!
