Hello,
I'm looking for some advice on or even just some examples of how other oVirt
users have configured networking inside their clusters.
Currently we're running a cluster with hosts spread across multiple racks in
our DC, with layer 2 spanned between them for VM networks. While this is
functional, it's 100% not ideal as there's multiple single points of failure
and at some point someone is going to accidentally loop it :)
What we're after is a method of providing a VM network across multiple racks
where there are no single points of failure. We've got layer 3 switches in
racks capable of running an IGP/EGP.
Current ideas:
- Run a routing daemon on each VM and have it advertise a /32 to the
distribution switch
- OVN for layer 2 between hosts + potentially VRRP or similar on the
distribution switch
So as per my original paragraph, any advice on the most appropriate network
topology for an oVirt cluster? or how have you set up your networks?
Thank you
