[SOLVED] General OVS question

[bcmike]

Hi,

I'm currently running Proxmox 6 (no intention to upgrade to 7 for a while) and want to implement an OVS bridge with an active-backup bond on two NICs. What I'm trying to achieve is physical switch redundancy as the switch is one of the last single points of failure.

I'm just wondering how reliable OVS has been for people using Proxmox as this is a full production environment that cannot suffer outages. I'm a little concerned that the network is now dependent on a deamon and that I've heard about race conditions between OVS and Ifupdown2 which we have installed on all of the machines. Our initial testing outside of production has been promising, but you never know about these things until you apply load.

Any general insights would be appreciated.

I personally am a fan of doing everything as simple as possible - and as far as i can see you should be able to get your desired setup with a regular linux bridge - no need for OVS.
* active-backup bond is supported
* you can put the bond as port into your bridge

Check the reference documentation on networking:
https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#sysadmin_network_configuration

I hope this helps!

Thank you for the quick reply. You're absolutely right, a Linux bond will do the exact same thing. I don't know why I thought this wasn't possible with a Linux bond and my mind went immediately to the most complicated solution.

I'll be breathing a little easier using the native Linux bridge and bond.
