<masayag> suggested me to send this email after our discussion on IRC.

Here is what's happening :
In 3.0, I was used to use one nic for transporting all my vlan network, and ovirtmgmt was part of these vlans.
in 3.1/vdsm 4.10, I systematically get a ovirt engine error when attempting to drag a new vlan network to the same nic : 
"Error while executing action Setup Networks: Internal oVirt Engine Error"
When looking at the host vdsm log I find this :
"Setup attached more than one network to nic em1, some of which aren't vlans"

So it tells me that the ovirtmgmt bridge is not a vlan and it can add an second vlan network to this card because of this.
But this is an error. ovirtmgmt is a vlan network I created by myself :
# vi ifcfg-ovirtmgmt

NM_CONTROLLED=3D"yes"
HWADDR=3D"44:1E:A1:3D:35:92"
BOOTPROTO=3D"static"
IPADDR=3D10.34.30.155
PREFIX=3D24
DNS1=3D193.52.69.50
GATEWAY=3D10.34.30.2
DEVICE=3D"ovirtmgmt"
ONBOOT=3D"yes"
TYPE=3DBridge

[root(a)khamsin ovirt-engine]# brctl show
bridge name     bridge id    &n= bsp;          STP enabled = ;    interfaces
ovirtmgmt          &n= bsp;    8000.441ea13d3592      = ; no            = ;  em1.30
virbr0          8000.00000= 0000000       yes

the dialog box in the DC tells it is a vlan 0, so there is a bug here, and plus this network management is not editable to change this.
at contrary, we see that the ovirtmgmt is correctlly shown as a vlan in the host network interfaces :
em1.30 (10.34.30.155)
ovirtmgmt

What can I do to use multiple vlan on a single nic?

problem. As a complementary step for defining the vlan for the management network manually, you should set it on the DC management network definition as well. I can guess that the checkbox next to the 0 vlan-id isn't checked, and even so - vlan-id 0 is a reserved tag. You should create new data-center. Right after (before adding a cluster to it) you should go to the management network of the data center and update the vlan-id to its actual value (30 in your case). Than you can add cluster to the DC and hosts. Attaching other vlans to em1 should be supported since the vdsm will get list of networks, all with proper vlan-ids. --===============3000711989720961335==--
