Just drag and drop NICs then configure it to active/backup! :) Atenciosamente, Arthur Melo Linux User #302250 2017-11-06 8:15 GMT-02:00 <magnus.isaksson@ilw.se>:
Hello! I'm new(-ish) to oVirt and have a question regarding network.
I currently use vmware, the hosts have 4 nic each and connected to two switches in stack(extreme), i have two vSwitch with two nic each setup in active/standby, with this i don't have to do anything with the physical switch.
So how do i do this setup on oVirt so i don't need to configure the switches? I know how to bond the cards, but i am afraid of a switchloop, so i just want to make sure that does not happen.
Regards Magnus Isaksson

I have a similar setup i am trying to achieve, but i would like to create 2 bonds to increase the bandwith and then configure 1 bond as a backup to the primary. Is there some way to do this?

Hello Bryan, I'm afraid it is not possible with oVirt. You can only attach NICs to a bonding via the way Arthur suggested. Regards, Petr 2017-11-09 16:41 GMT+02:00 Bryan Sockel <Bryan.Sockel@altn.com>:

I would argue that such a setup is problematic. The bond link goes down only when all its slaves are down, therefore, if you loose one slave, the BW is decreased and the backup will not take over. Using 3 or 4 slaves bond can allow you to get both increased BW and redundancy. Thanks, Edy.

Understood. Our typical server deployment is primary network link to one switch and back up link to a second switch. This allows for my network admin to do switch maintenance with out any down time. So in our ovirt deployment we have bonded link for one server going to switch 1 and on server 2 we have a bonded link going to switch 2. We have to manually put the server in maintenance mode before he could do any switch maintenance. If there was an actual switch outage, we would have to wait for the system to restart the HA VM's on the other server. I know there are ways on the switch side that we can make both switches appear as a single switch and possibly create a bond across switches, but that is not something we have implemented.

Note that you can also explore the option of setting up STP in your network (which will handle the loops). Thanks, Edy. On Thu, Nov 16, 2017 at 8:33 PM, Bryan Sockel <Bryan.Sockel@altn.com> wrote:
