Is this possible?
I have 3 hosts with each four physical interfaces.
On one of them, I have a vlan defined which I'd like to use for
ovirtmgmt. However, after installing the host, it says that the
ovirtmgmt network is missing on it and if I try to assign ovirtmgmt I
can only do it on the physical NIC's
Any ideas?

Technically, it is possible, I used to do it at the very beginning
but... if you can, the best practice is to dedicate a physical nic to
the ovirtmgmt network as a non-tagged vlan.
Imagine you install your node on an access port, then you want to add
bond, then the ovirtmgmt on a tagged vlan... each time you change your
port config to match to your node config, you can loose ssh connection
at any time.

Hi Nathanaël,
Yeah, I think I'll have to just use a physical NIC for the ovirtmgmt.
Too bad, it would be nice to be able to separate it from the standard
network.

Actually in several environments I can use globally only 4 network
adapters, but they are all 10Gb/s.
So in this case is a shame to use a pair of them for ovirtmgmt only...
I use 2 of them in bonding (802.3ad) for ovirtmgmt and VMs, and 2 of them
for iSCSI, migration network and NFS access
The culprit is to pre-define the bond on the host and set ovrtmgmt as a
vlan based network with the vlan id that is necessary in your case.
Eg on one environment of these my vlan for ovirtmgmt is 68
In this case on the host there will be bond0 before setup and then after
setup they will be created bond0.68, bond0.65 interfaces and ovirtmgmt
bridge and vlan65 bridge
8: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP group default qlen 1000
link/ether 18:03:73:0d:e9:41 brd ff:ff:ff:ff:ff:ff
24: bond0.65@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue master vlan65 state UP group default qlen 1000

[root@ov200 ~]
with the ovirtmgmt bridge on bond0.68 device
In another environment I have 4 interfaces and ovirtmgmt not set up as vlan
based, but I can configure the switch ports as trunk with vlan 187 enabled
and as default vlan set the 68 one, so that if packets are not tagged they
go through that vlan.
In this case on one host I have to preconfigure the bond0 and then at the
end of setup I will have something like this:
45: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
master ovirtmgmt state UP group default qlen 1000
link/ether f4:e9:d4:d6:15:a0 brd ff:ff:ff:ff:ff:ff
46: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue

link/ether f4:e9:d4:d6:15:a0 brd ff:ff:ff:ff:ff:ff
inet 10.4.192.47/24 brd 10.4.192.255 scope global ovirtmgmt
valid_lft forever preferred_lft forever
inet6 fe80::f6e9:d4ff:fed6:15a0/64 scope link
valid_lft forever preferred_lft forever
47: bond0.187@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UP group default qlen 1000
link/ether f4:e9:d4:d6:15:a0 brd ff:ff:ff:ff:ff:ff
inet 10.4.187.102/24 brd 10.4.187.255 scope global bond0.187
valid_lft forever preferred_lft forever
48: bond0.65@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue master vlan65 state UP group default qlen 1000
link/ether f4:e9:d4:d6:15:a0 brd ff:ff:ff:ff:ff:ff
49: vlan65: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP group default qlen 1000
link/ether f4:e9:d4:d6:15:a0 brd ff:ff:ff:ff:ff:ff
and
# brctl show
bridge name bridge id STP enabled interfaces
;vdsmdummy; 8000.000000000000 no
ovirtmgmt 8000.f4e9d4d615a0 no bond0
vlan65 8000.f4e9d4d615a0 no bond0.65
vnet0
vnet1
So the ovirtmgmt bridge is on bond0 and the VM dedicated bridge (vlan65) is
on bond0.65
And on bond0.187 I have the ip dedicated to live migration.
The important thing is to presetup the bond and make the right choice at
the beginning about ovirtmgmt, if you want ovirtmgmt vlan based or not.
And also configure accordingly the switch ports, of course.
HIH,
Gianluca

Thanks guys.
That is awesome info, I’ll see if I can make it work

I changed from non-vlan to vlan on our systems which are all ovirt node installs, you need
access to the nodes/hosts that doesn't use the ovirtmgmt network ( another
interface/KVM/console). I believe it was /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt
I edited then restarted the neworking.
