Note that you can also explore the option of setting up STP in your network
(which will handle the loops).

Thanks,

Re: [ovirt-users] NIC Bonding

2017-11-16 Thread Bryan Sockel
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.

Thanks
Bryan Sockel

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.

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.

Magnus Isaksson

Hello Bryan,

I'm afraid it is not possible with oVirt. You can only attach NICs to a
bonding via the way Arthur suggested.

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?
