Dear all,
It's really a shame that I cannot complete my job. So I have to ask for
help here.
I installed the OVN and run the northd and controller successfully. Also
,I added the fail_mode(secure) in br-int.
Then, I followed the setup.sh of env1 of OVN-Tutorial.md.
ovn-nbctl lswitch-add sw0
ovn-nbctl lport-add sw0 sw0-port1
ovn-nbctl lport-add sw0 sw0-port2
ovn-nbctl lport-set-addresses sw0-port1 fe:54:00:a6:6f:5a
ovn-nbctl lport-set-addresses sw0-port2 fe:54:00:88:27:ce
ovn-nbctl lport-set-port-security sw0-port1 fe:54:00:a6:6f:5a
ovn-nbctl lport-set-port-security sw0-port2 fe:54:00:88:27:ce
ovs-vsctl add-port br-int vnet0 -- set Interface vnet0
external_ids:iface-id=sw0-port1
ovs-vsctl add-port br-int vnet1 -- set Interface vnet1
external_ids:iface-id=sw0-port2
In this test, I have two VMs, and the "vnet0" and "vnet1" is the dev in
host., the "fe:54:00:xx:xx:xx" are these dev's macaddress. But I find
the OVN didn't work. whatever I do, the two VMs always cannot
communicate with each other.
And i run " $ ovn-sbctl show", it didn't show anything. I guess in the
last step, I didn't add the set options in the OVS.
At the same time, I run the ovs-ofctl show, it suggest:(different from
the tutorial book)
root@troy-PC:~# ovs-ofctl show br-int
+ ovs-ofctl show br-int

I want to use the OVN to control the two VMs network(just like iptables
to control the connection behaviors). But in the guide book and
examples, they use it in sandbox and doesn't add any VMs, if possible,
could you give me some guidance about the OVN usage with VMs please?
Best regards,
Troy
