Hi and thanks for the reply.
I have now solved the issue. If anyone is wondering how:
Veeam was using DNS to connect to everything meaning it would always connect to the
management IP behind the FQDN of the server.
Wat I did was:
- Give every host an IP in the Backup VLAN
- Set up DNS Policies so that in my BACKUP VLAN the FQDN always resolves to the hosts IP
in the backup VLAN
Veeam is now happily using the 10Gbps bond and speeds have increased significantly.
It adds a little bit of management overhead having to manage a seperate DNS Scope but it
shouldn’t really matter.

If the host does not have an IP on the 10G network then it cannot use that interface.

Hi all
I was wondering if anyone managed to get Veeam working with a dedicated backup VLAN
instead of sending traffic over the ovirtmgmt interface.
We have an OLVM setup (version 4.5.5-1.42.el8) with 3 hosts in 1 cluster for now.
Each host has a 1Gbps NIC pair in a seperate management LAN that is only used for
ovirtmgmt
Each host also has a 10Gbps NIC Bond where all the VLAN's are trunked including a
dedicated Backup VLAN. The hosts do not have an IP in this Backup VLAN configured (is this
needed?)
Each host also has 2 NICs dedicated to storage backend (iSCSI Multipathing)
Our Veeam Appliance and workers are setup in the Backup VLAN and they can communicate with
the backup repository that is also in this VLAN.
When we take a backup, however, we see that the ovirtmgmt network is maxed out on trafic,
which probably shouldn't happen.
We come from a VMWare environment where the backup proxies handle all the trafic through
the backup VLAN without relying on the management network and I was expecting it to work
similarly
Has anyone managed to get this working as I envision it?
Or is the solution to simply link ovirtmgmt to the 10Gbps bond and skip the dedicated mgmt
networking?
I've also opened a ticket with Veeam for this, but for now I'm just getting
questions from them and no real answers.
If I get a useful solution from them I will also post it here
