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. ----- Original Message -----

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_caps.... https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/ovs/ovs_after_get_stats... 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.

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.

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.

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 because I'm going to put them on different NICs?
It says "specified VLAN ID is already in use".
