Subject:  Re: [Users] unsuccessful at creating bonded interface

So far I have been unable to successfully create a bonded interface on
ovirt node 2.5.5-0.1.fc17, either mode 1 or mode 4 (and I will have need
of both going forward).

When I try it, the config fails, but if I log in I see the bonded
interface.  Restarting gives the error cannot change config there are
still slaves attached.  Rebooting, eliminates the config and what I had
originally come back (but at least the node
 is pingable again).

Can someone point me in the right direction here of how to get this
feature working?

Hi Jonathan,
Can you please send the relevant logs of engine & VDSM that include the
error that you get when you try to create the bond?

Thanks!

ButŠ before I could find the relevant part in the engine log, I think I
figured out the problem.  There is a little config button when you drag
the interfaces and network together that I didn't notice before.  I guess
I just assumed that when you drag them all together the interface config
was moved from em1 over to bondX.  My assumption was incorrect.  Now that
I have mode1 working, ill try a mode4  :)

Thanks!
