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.
As long as your switch ports are configured correctly, adding vlans
is
simple. I don't put anything in maintenance to do it.
I have a bonded NIC (2x1Gbps); I presume I just need to tell the switch
that this is a vlan trunk?
Just go to networks -> New

Check the "enable VLAN tagging" and enter your vlan. You don't really
need
to change anything else.
Do I need to edit ovirtmgmt and enable vlan tagging too?

Now you have a logical network and a Vnic profile for this vlan:

Now you need to tell Ovirt what physical NIC you want this to operate on.
Go to your host and select "Setup Host Networks"
Drag the new network onto the NIC or bond you want to use:
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?

You can click the pencil and have this interface get an IP address if you
want, but, you don't need to - your vms will get IPs. So you can leave
this
all alone in here:
This would be a host address on the VLAN? If so, I agree -- I don't
think most VLANs will need that.

Now when you are creating a VM, you can attach this Vnic profile. You
could also add the Vnic to an existing VM.

And that's it. If you have the VM configured to DHCP, and you have a dhcp
server listening on that Vlan, it will work. If your VM doesn't get an
IP,
check your router's DHCP logs to see if it hears anything from the Mac
address of your VM's nic. If you also have a DNS resolver that adds DHCP
entries, and your VM has a hostname configured in cloud-init, you'll even
be able to resolve the FQDN to your VM immediately.
Yeah, pretty much all VMs are DHCP.
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.
Hope this helps!
Indeed. Major open question right now is ovirt-shell ;)
