For an all-in-one, what I would suggest is the following procedure:
On your PC, create a dummy NIC via:
sudo ip link add dev dummy_0 type dummy
sudo ip link set dev dummy_0 up
It's important that the name will be in the dummy_* format.
Following that, go back to the GUI, select the host and hit Refresh Host
Capabilities.
You should see the new dummy_0 device as a host NIC.
Create a VM network, and under the host Network Interfaces tab hit Setup Host
Networks.
Drag and drop the new VM network on dummy_0 (Don't give dummy_0 a boot protocol
or an IP address
in the edit network dialog).
At this point you should be able to attach VM vNICs' to the new VM network and
they won't
be physically connected to any other network, but they'll be able to talk
amongst themselves.
The "private network" feature is planned* for oVirt 3.5, so in the future
you'll be able
to just define a network as a private one and everything will work
automatically.
* No promises!

Subject: [Users] networking: basic vlan help
Hello again,
I'm new to VLANs and have a few questions. Right now I just have the mgmt
interface (bridged with eth0) on my all-in-one oVirt test setup. I want to
separate some VMs from the public facing net, which I think means that they
need to be on a different VLAN. I created two new networks, pubX and
privY, with vlan ids X and Y, but couldn't assign them to eth0 because the
current mgmt network is non-VLAN. I was about to enable VLAN tagging on the
mgmt network, but I wanted to make sure that doing so wouldn't do anything
to eth0 that would disrupt access to it (I only have remote access and don't
want to lock myself out). Also, if it is safe, does the mgmt vlan tag id
matter? is 0 the right value?
Any/all help, hints, tips or references to examples/links greatly
appreciated.
Robert

wouldn't disabling 'vm network' on the mgmt network to simply allow the
VLAN'd networks for VMs be simpler?
also, since this question/use-case came up several times past 2 weeks -
do we have a good enough user feedback on why user can't attach a
logical network to the same interface, suggesting there is a non-vlan'd
network visible to VMs, and that if they want to use VLAN'd networks on
the same nic, they should disable the 'vm network' role on the
non-vlan'd network?
