Does 4.3 still support ovirt-shell?
I cannot re-image, I need to upgrade. That only means I need to do
it in
two steps, 4.1 -> 4.2 -> 4.3.

I have a bonded NIC (2x1Gbps); I presume I just need to tell the switch
that this is a vlan trunk?
You just need to tag whatever VLANs you want to get through.

Do I need to edit ovirtmgmt and enable vlan tagging too?
What for?

So there's nothing special I need to set up on the host? I just need to
add the new virtual networks to the existing bond/interface?
That's how it works for me.

This would be a host address on the VLAN? If so, I agree -- I don't
think most VLANs will need that.
I think maybe you need to if you want to be able to access the HE from that
vlan? I've never needed to.

Yeah, pretty much all VMs are DHCP.
What I do is leave them on DHCP, that way they come "UP" right away. Then
I can reserve their IP in the router.
Thanks. I'll try this out. I still have at least 1-2 months
before I can
even entertain migrating, and it could be as long as 3-4 months. So I
have time to think and plan.

Indeed. Major open question right now is ovirt-shell ;)
