Yes, if support for it will be added to our OVN solution.
For this to work, we will need:
- Use OVN (external network) solution in oVirt.
- Use OVS cluster in order to connect the external network to the host
network using physnet.
- Introduce support in the OVN solution to enable trunk ports towards the
VM/s.

For the last point an RFE is required.

Thanks,
Edy.

Thank you for responding. Do you think this would this work with OVS?

It is not supported because of how traffic is passed to a vlan by its 
base interface.
When packets arrive to the nic and on top of it there is a vlan, any 
packet with a tag that matches that vlan will be forwarded to it and 
from there to the bridge.
Leftovers (any other tags or non tag packers) will get forwarded to 
the bridge which is directly connected to the nic.


So you cannot have one tag and one untag using the same base interface 
(bond in your case).


Thanks,
Edy.

Correct. On the host i have 1 management interface (ovirtmngmt) and 1 bonded 
pair of 10GB interfaces (bond0)

Under Networks I have created the following networks.
VLAN70 - Tagged with 70
20GBBond - no tagging

In the host I added both VLAN70 and 20GBBond via the Setup Network. I dragged 
the two networks interfaces and dropped on the bond0 nics.

I created two VMs and assigned interfaces.
Test1 - Attached VLAN70
I ping 10.0.70.1 (the gateway) and it works.

Test2 - Attached 20GBBond and create a eth1.70 interface in the OS.
I can not ping 10.0.70.1, since VLAN70 is attached to Test1.
If I stop Test1, remove the VLAN70 and delete the VLAN70 network I can then 
ping 10.0.70.1 from the eth1.70 interface on Test2.
However, both can not exist at the same time.

[ovirt-users] Re: Ovirt - Bonded NICs - using as tagged and untagged at the same time

2018-10-26 Thread Petr Horacek 
Just to make it clear, by "make an interface" you mean you created new
logical VM networks, one without VLAN set, the rest with VLAN? You should
attach those networks to your bonding in Setup Networks dialog. Then you
should be able to connect VMs to any of these networks. On untagged VM NIC
you can create whatever VLAN interface you want.

What do you mean you can no longer use it. You are trying to ping from VM1
(connected to VLAN network) to VM2 (connected to untagged network, but with
VLAN interface inside VM)?
