Hi all,

<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="yes"
HWADDR="44:1E:A1:3D:35:92"
BOOTPROTO="static"
IPADDR=10.34.30.155
PREFIX=24
DNS1=193.52.69.50
GATEWAY=10.34.30.2
DEVICE="ovirtmgmt"
_ONBOOT_="yes"
TYPE=Bridge

[root@khamsin ovirt-engine]# brctl show
bridge name     bridge id               STP enabled     interfaces
ovirtmgmt               8000.441ea13d3592       no              em1.30
virbr0          8000.000000000000       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?
