[Users] Error on Setting up VLAN

[Alessandro Bianchi]

Hi everyone and happy new year first !

I'm setting up a test host using VLAN

It holds 2 VM's so I

- Stopped the two VMs and removed the "public_10" network from the NIC
- edited the "public_10" network, checked "enable VLAN tagging" and set 
10 as VLAN identifier
- assigned the "new" edited network to the VMs NIC
- edited the HOST network, clicked the pencil on the relevant NIC and 
clicked "sync network" since it showed the network as "not synced"

Ovirt tried to setup the network but ended with "cannot up interface" 
error and I lost contact with the node

Ovirt is 3.3.2 on Fedora 19 (it is AIO)

Here is the log:

How may I amend the configuration files?

Any hint?
