We have DEV and QA is the same "data center" but on the network side of
things they are on different switches, so they reused some VLAN IDs.
No problem, my server has 4 NICS.
But how do I tell ovirt its ok to have 2 networks with same vlan ID

It says "specified VLAN ID is already in use".

Hi Bill,
Currently the engine blocks adding two networks with the same vlan id to a data center.
If you think there is a use case for having more than one network with the same vlan id in
a DC, please open an RFE.
As a workaround, you can add a network with a 'fake vlan id' (a vlan id that is
not in use by the dc).
And using 'vdsm before network setup hook' (https://bugzilla.redhat.com/1057637)
translating the 'fake vlan id' to the desired one.
Alona.

thank you very much for the reply.
I'm trying to find more about how to setup a 'fake vlan id', but so far
have not been able to find anything. The link you mentioned mentioned a
link about setup_network_hooks, but the link doesn't work any more.
I have found there is a directory called
/usr/libexec/vdsm/hooks/before_network_setup.
This doc http://www.ovirt.org/develop/developer-guide/vdsm/hook/network-nat/
suggests using "|sudo engine-config -s CustomDeviceProperties"
|
but I haven't found any descriptions on how to use it.
This doc goes into a little detail:
http://200.1.19.60/ovirt-engine/docs/manual/en_US/html/Administration_Gui...
but what property define vlan number and how do I tell it that this
number is really that number?
Thanks.

It's not a must to use the custom properties in your case, although it
will be more flexible.
The idea is to use a 'fake' vlan, say 999, and build a hook on the
host to intercept the request, detect that the vlan id is 999 and
replace it with the correct vlan id.
Using the custom properties just allows you to define the target vlan
id on the Engine and not in the hook code.
You can review this reference for the vdsm part:
http://www.ovirt.org/develop/developer-guide/vdsm/hooks/
but what property define vlan number and how do I tell it that this number
is really that number?
If you look at this hook as an example:
https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/extra_ipv4_addrs
You need to look for the 'vlan' attribute, check it is 999 and
overwrite it with your ID.
Thanks.

That's because you need to fake it back as well, otherwise Engine
complains that what it requested is not what exists.
So you need another two hooks: after_get_caps and after_get_stats
Please look at these two:

https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/ovs/ovs_after_get_st...
To see what you need to change, issue the two reports on your host:
# vdsClient -s 0 getVdsCaps
# vdsClient -s 0 getVdsStats
If I try detaching the "custom" network I get an error:
So obviously I'm missing something.

My hook script, please excuse the poor scripting since this is my first
python script.
I would suggest posting a patch on gerrit (https://gerrit.ovirt.org),

"""
Tweak an interface defintion so that it uses an alternate port group.
It applies on a per vnic basis, it gets triggered and used by event:
* before_network_setup
This hook can be used to allow multiple NICs with same VLAN ID
in case they are used on multiple hardware NICs.
