Hello,
I am trying to set up an oVirt environment using OVH servers. So far I have installed an engine (4.2) and a node. The node is attached to a NAS through a vRack https://www.ovh.co.uk/solutions/vrack/network-technology.xml. I am using one vlan to connect it, which is the management network


However it is not a perfect setup (cf attached screenshot). The management network is in  "Out-of-Sync" state.
on the node :
# ip addr
28: eno4.100@eno4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master ovirtmgmt state UP qlen 1000
    link/ether 0c:c4:ff:7a:6c:13 brd ff:ff:ff:ff:ff:ff
29: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether 0c:c4:ff:7a:6c:13 brd ff:ff:ff:ff:ff:ff
    inet 10.100.0.11/24 brd 10.100.0.255 scope global ovirtmgmt
       valid_lft forever preferred_lft forever

It does not seem possible to add extra vlan. I wanted to have one for the vms and one for the hosts.
Can you give me some help or guidance ?

Also generally speaking do you think such a setup is fine ? 

Thank you
Fabien
