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 [image: Screenshot from 2018-03-15 09-03-37.png] 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

If you are limited to a single VLAN, I would use this as a single logical network in oVirt. To isolate the traffic between VMs, I would use external logical networks on the ovirt-provider-ovn.
Hello, Thank you for the answer. I'll try your solution. Fabien On Thu, 15 Mar 2018 at 11:59 Dominik Holler <dholler@redhat.com> wrote:
