Yes, under networks you can create new and specify VLAN tags.
When you add NIC's under the VM, you choose the new Network you chose
and the interface on the VM will be automatically then on that VLAN.

Hi, is it possible to use different VLANs with one NIC in ovirt?

Hi Joseph, I did that but the problem is that I have an ovirtmgmt network by default and
another network that is a VLAN, VLAN 5 exactly. But VMs that are in VLAN 5 cannot go
outside. Maybe it could be because the traffic on ovirtmgmt is unlabeled and on VLAN 5 it
is tagged. Or maybe I have to create some internal route so that VLAN 5 packets can exit
on ovirtmgmt. I don't know what exactly happens and I would like to help me.

How is your switch port configured?
The switch port, in your case, would have to be set up in trunk mode, for the vlan 5
tagging, then also have a native vlan defined, for the untagged management packets.

If the route to outside is via untagged network, VLAN 5 should not able to
reach outside.

Yes.
Or maybe I have to create some internal route so that VLAN 5 packets
can
exit on ovirtmgmt.
This would break the isolation between VLAN5 and ovirtmgmt.
Do you want to separate VLAN5 from ovirtmgmt?
I don't know what exactly happens and I would like to help me.
Maybe you know already what happens, I just did not get your intention.
You can have separate layer 2 networks using VLANs, which are isolated.
They could be connected via a router, which can be a physical device, a
machine outside oVirt or
even an oVirt VM which has a vNIC for each network.
Most simple would be to connect the VMs to ovirtmgmt, but this way the VMs
could harm the physical hosts.
