Re: [ovirt-users] OVN between two different datacenters with different networks

2018-04-13 Thread Vasily Lamykin 
Very big thanks, In your solution I want fix only one...
" tunneling-IP is IP-of-host-of-engine-2"
For me - works variant is IP of host2 , which can provides access to engine1

The subnet is used to configure OVN's internal DHCP server.
This means you use DHCP to assign IPs to the vNICs, which is already a good 
test if the VM is connected as expected.

Please note that per host only a single OVN central is supported!

Please check via
sudo ovn-sbctl show
on engine1 if both hosts are connected to OVN central engine1.

Probably the host of engine2 is configured to use engine2 as it's OVN central. 
Probable the host of engine2 has to be connected to OVN central engine1 and the 
tunneling interface might require some configuration.

Both is handled by executing
/usr/libexec/ovirt-provider-ovn/setup_ovn_controller.sh \  IP-central 
tunneling-IP key_file cert_file ca_file on the host.

Probably
IP-central is IP-of-engine1
tunneling-IP is IP-of-host-of-engine-2
and key_file cert_file ca_file has to be stolen from host of engine1 and copied 
in a new location on host2 and configured on host2.

[ovirt-users] OVN between two different datacenters with different networks

2018-04-10 Thread Vasily Lamykin 
Hi, all
I try to configure ovn in engine, what I do by step:
1.Created network test1 with external ovn provider on engine1
2.Created subnet for this network
3.Connect engine2 to engine1 ovn provider(through “add provider”)
4.Successfully imported network test1 on engine2
5.I see subnet’s on all engines
6.Created 2 VM with nic in network test1 on both engines
7.Assigned ips from one subnet(192.168.10.0/24) to all VMs

Expected results: VM from engine1 can ping VM from engine2 in same subnet in 
ovn network test1

Now, I don’t have ping ability between two VMs

ovn-nbctl show
switch 54beaa3c-de8f-435f-b132-8542ddeb4b4b (test-ovn-phys)
port b580d44d-e616-42dd-9e17-63983d0f91e5

port cfd5f32c-00a7-419e-8bbe-27518a4c74dc
addresses: ["00:1a:4a:16:01:00 dynamic"]

node from engine1 with testVM
vnet0:  mtu 1500 qdisc pfifo_fast master 
ovs-system state UNKNOWN qlen 1000
link/ether fe:1a:4a:16:01:01 brd ff:ff:ff:ff:ff:ff

node from engine2 with testVM
vnet0:  mtu 1500 qdisc pfifo_fast master 
ovs-system state UNKNOWN qlen 1000

   valid_lft forever preferred_lft forever

How can I do ovn connection? What I did wrong?
