You should be able to use bonded interfaces with an IP on each VLAN
Interface for the ovirt hosts and the engine. For example, here is the
IP configuration for one of our VLANs.
10: bond3: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UP group default qlen 1000
link/ether 00:1b:21:5c:80:39 brd ff:ff:ff:ff:ff:ff
inet6 fe80::21b:21ff:fe5c:8039/64 scope link
valid_lft forever preferred_lft forever
24: bond3.311@bond3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UP group default qlen 1000
link/ether 00:1b:21:5c:80:39 brd ff:ff:ff:ff:ff:ff
inet 192.168.111.201/24 brd 192.168.111.255 scope global bond3.311
valid_lft forever preferred_lft forever
inet6 fe80::21b:21ff:fe5c:8039/64 scope link
valid_lft forever preferred_lft forever
bond3.311 configuration is managed in the
/etc/sysconfig/network-scripts/ifcfg-bond3.311 file.
IMO setting up bonded NICs with VLAN tagging is one area where ovirt
falls short. You essentially have to configure your networks twice.
First using the /etc/sysconfig/network-interface files and then inside
of the engine itself. VDSM may also need to be configured to use ifcfg
persistence in the config file.
cat files/vdsm/vdsm.conf
[vars]
ssl = true
net_persistence = ifcfg
[addresses]
management_port = 54321
Your switch ports also need to be configured to support 802.1q networking.

Hi,
I setup oVirt a few years back… now that the HCI is real, I am
revisiting it. I have deployed with Gluster, and am now moving on to
networking.
I come from a VMware shop and normally we trunk all the network ports
exposing all VLANs to the hosts and place VMs in Portgoups that are
tagged with VLANs.
I did manage to do this years back but I am struggling to get this to
work today. I had pretty limited hardware back then and I thought I
installed using vlan tagging and trunked ports, but I don’t see any
option to do this using the glusterfs and hosted engine setup.
Each host has a dual port 10Gb NICs I use one for storage that is
connected to my storage network and one for ovirtmgmt. (I need to add
another of these for redundancy down the road, but no money for that
at the moment)
The hosts also have 4 x 1Gb ports. So in lieu of being able to
configure vlan tagging to trunked ports on hosted engine deploy, I am
considering cabling up a 1 Gb port on each in my management services
VLAN and when it is all up and running create another logical network
(or several of them as I think these equate to what is a vlan tagged
port group in VMware) with the 10Gb NIC backing for VMs.
Does that sound reasonable? Or if anyone can point me to any docs
that describe how to deploy to a specific VLAN with trunk ports, that
would be nice as well as I won’t have to actually go to the office and
run additional cables.
Appreciate any advice
Bill
