Advanced bonding how-to
Can someone point me out to the RH's docs on advanced bonding configurations . We have HP server with 4 NICs onboard . One used for rhevm , another is directly connected to some logic network with statis ip . eth2 and 3 I configured as bond0 . I expected to have an option to configure multiple bonding interfaces . I found a video presentation on this issue . What about a doc?

I am testing RHEV 3.0 with hipervisor node 6.2 and I found very interesting this document, specially the part about multiple VLAN netowk layout with a NIC bond, but I have problems with the rhevm network.
I can create a bond to link the management logical network, but after that, I'm unable to attach any other logical network to that bond. Do you know if is this posible?
Thanks
I guess your rhevm network is not tagged. Currently, RHEV does not allow setting tagged and untagged networks on the same interface
Yes, my rhevm network is not tagged, thanks for your advice. I have made some test and configuring the rhevm network as tagged I can see that is not possible to add more netowks over the managemente netwok. I opened a case with RedHat support and this is waht they told me:
"In RHEV3, it's not currently possible to add more logical networks on top of rhevm network. It doesn't matter the interface used for rhevm is bonded or not. This is a bug and a fix is being worked out with high priority. An async errata will be released soon.
In the meantime, you can try the work around of manually setting it up via /etc/sysconfig/network-scripts/ifcfg-xxx files. However, I recommend waiting for the fix. Please note that we do not support mixing tagged and untagged vlans. So you should use a tagged vlan for rhevm network as well once the fix is released. Only then you will be able to add more tagged logical network on top of rhevm."
Then, it seems at this moment is not possible to add more logical networks in the same interface where is configured the management network.
Thanks for your help.
Hi Antonio,
Have you heard anything new about this fix?
I'm in the same situation.
Best regards,
