Re: [ovirt-users] Communicate between the guest vm's hosted on, different hosts on different data centres using OVS

Hi Suresh,
You would need to connect the two OVN instances somehow. If it's
just two single hosts, I think the easiest way would be to create a VPN
connection between the two hosts with OpenVPN or the like and then add
the tun/tap interfaces into the OVN on each box. You might run into
problems if you start adding more hosts though, as if the host with the
VPN goes down it would disconnect the two datacenters.
If the two datacenters are on the same physical network (ie, you just
mean oVirt datacenter and not different colocation providers) then
adding a VLAN to the NICs connected to the OVN interface would work.
You would probably have to setup some sort of channel bonding/LACP as
you add more hosts, but OVN should be able to handle that simply enough.

Hello,
I have configured OVS network on oVirt 4.1.1, following the document
https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/
I have created OVN Provider, and created new Logical Network for OVS using
OVN Provider. I have synced the network also selected OVS when I created
the cluster.
I have two data centres and each data centre has one host each.
Now I have created VM's selecting OVS network (not ovirtmgmt). VM's in the
same data centre can talk to each other.
How do i make the VM's hosted on different data centre can talk to each
other?
Appreciate your help in advance,
Sincerely,
Suresh.

Hi Charles,
We use an Ethernet cable to connect between the hosts through 10G port.
We want to use the guest VM's hosted on different hosts 10G network. oVirt
already supports SR-IOV. So we should guest 10G speed for our VM's.
In KVM we can create a second bridge and add the 10G interface to the
bridge would do the trick.
But in oVirt how do we do this? We want to use our OVs network, which was
created using OVN Provider.

Hmm, so you have 2 10G ports on each host. 1 port is currently in use
with oVirt, and the other isn't? Then I think you just add a new
network in the Networks tab called OVNLink, then go into the Hosts tab,
click on each host and then on the Network Interfaces tab in the bottom
of the window and assign the unused 10G network device to that link.
I haven't used OVN with oVirt, but that would work with regular
networking so I think it should work with OVN.
If the link is already in use, you should be able to do the same thing
only when you add the new network set it up with a VLAN ID. If you are
going through a switch then the switch will have to be setup to handle
the VLANs.

New subject: Communicate between the guest vm's hosted on, different hosts on different data centres using OVS
I have created a separate network for 10G network and made central server
part of it. After that configured the OVN controller using vdsm-tool
vdsm-tool ovn-config <OVN central server IP> <local IP used for OVN
tunneling>
Then added OVN provider to oVirt as an external network provider and
created a new network based on OVS. Now the new VM's we create use this new
network.
Thanks for your help!
