IIUC your question, you have various options:
1. GUI 2. SDKs 3. CLI
you need to create network in DC, attach it to cluster, attach to host NIC/s (if you want it to be atomic operation, i.e you expect connectivity loss during the operation/s, setupnetworks should be used, otherwise you can use attach-network dialogues in UI)

please see this [1].
[1] http://www.ovirt.org/Features/Design/Network/SetupNetworks
and it is possible to disable this automatic network bonding on the engine so that we can use separate networks on the network interfaces..?
attaching logs would help, but i guess it happen cause you did not saved your host network config, i.e when host got rebooted, it performs roll-back to old config, this is actually disaster recovery mechanism.

engine does not need to be connected to storage network. it does all storage access via the hosts.
It worked fine after manually tweaking the sysconfig/network-scripts, but this config was then shortly overridden by Engine discovering and trying to use the second NIC for bonding with ovirtmgmt.
the engine isn't trying to bond by itself. have you bonded the interfaces on the host setup-network dialog?

Then I'm happy with the explanations that it is supposed to work the way I initially expected.. That all operations are actually carried out on the nodes is good news, and should solve all worries. I'll go back and see what is actually going wrong on the engine and try to fix it. I'd love to reinstall the engine, but as I can't find any documentation on how to reliably move configs from one engine to another, and I was brave enough to already put ovirt into production with a number of hypervisors, I'm somewhat limited to what I can/dare to do. ----- Ursprungligt meddelande ----- I have also more than one interface in my Engine but never had this problem, I don't have a ovirtmgmt network on my Engine hosts thats not needed. I can understand the need for the engine server to have a nic/ip in the managment network AND a nic/ip in the storage network. I also have a separate access/public network and ilo network. It looks like you have a bond defined somewhere and it looks like you have vdsm running on your engine server. Just looking at my two engine servers and none has more than one ip.

My engine hosts don't host the iso/export domains so don't need to be in the storage network. If you have the possibility, go back to a bare machine with NetworkManager turned off and network turned on. Make sure networking is working as expected, eth0=ip in managment, eth1= ip in storage.

Hmm.. yes, I do have the storage network configured in DC and Cluster, and also attached to all my hypervisors. The question is just how I also attach it to the Engine server, as this isn't visible as a node in the GUI?
i think this could be done with puppet, afaik some work for integrating it to oVirt been done lately, though not sure if it's already available,
oved?
Not sure I understand the use-case, but currently the integration doesn't allow provisioning of any kind on hosts. Oved

Thanks Michael,
I'm still trying to get my head around this, but I can't see how I configure the networks on the engine? For nodes and AOI it's OK, but in my case I am running the engine as a separate server which is not a node and does not show up as a Host in the GUI. Or do I need to add the engine as a host in the GUI as well, to be able to configure it?
IIUC your question, you have various options:
1. GUI 2. SDKs 3. CLI
you need to create network in DC, attach it to cluster, attach to host NIC/s (if you want it to be atomic operation, i.e you expect connectivity loss during the operation/s, setupnetworks should be used, otherwise you can use attach-network dialogues in UI)

Hi,
I want to use two network interfaces connected to different networks in Engine (3.3), where one is for ovirtmgmt and one is for a separate storage network. It works fine for a minute or so after rebooting Engine, but then the configuration is changed by Engine, connecting both interfaces to bond0 and losing connectivity (as obviously you can't bond those two interfaces when they are connected to separate physical networks..). What is the mechanism doing this,
please see this [1].
[1] http://www.ovirt.org/Features/Design/Network/SetupNetworks
and it is possible to disable this automatic network bonding on the engine so that we can use separate networks on the network interfaces..?
attaching logs would help, but i guess it happen cause you did not saved your host network config, i.e when host got rebooted, it performs roll-back to old config, this is actually disaster recovery mechanism.
