Today I shall be moving a whole bunch of virtual wires to #openvswitch. What could possibly go wrong? 😂

Also going to give https://github.com/PLVision/open_vmonitor a try as a GUI to #openvswitch

Going to take another look at using #openvswitch on #debian bookworm as now there are sensible systemd units for it that start it up before networking.target. I used it a long time ago but it was tempremental because of the startup scripts not always starting up in time. When it did work it was great though.

this one's for the enthusiasts, but if anyone else out there is using #openvswitch on #fedora , note it'll probably break on upgrade to #fedora38 . see https://bugzilla.redhat.com/show_bug.cgi?id=2188710 , workaround is in the first comment.

Hat wer Erfahrungen, wie man im Proxmox + Open Vbridge eine Netzwerkverbindung einer VM debuggen kann? Ich würde gern eine zweite VM mit wireshark aufsetzen, die einen Spiegelport der zu untersuchenden VM hat....
#proxmox #wireguard #OVS #OpenVSwitch

So.... bis auf den Access-Switch im Büro sind jetzt alle Router, Firewalls und Switches virtualisiert. Performance sehe ich gerade keine Unterschiede, weder messbar noch gefühlt. Fast 1kW weniger Dauerstromaufnahme und das ohne Klimaanlage, die derzeit nicht anspringt.
Lizenzkosten 0€, Einrichtung ca. 25h, Investitionen 280€ für LWL-Netzwerkkarten und viel dabei gelernt.

I am finding it useful to write these blog post on basic aspects to remember some details and helping me to better understand OVN. I hope to continue with these entries and add more advanced topics.

Still motivated to write about #OpenvSwitch :). New blog post: "OpenvSwitch. Geneve tunnel" https://albertomolina.wordpress.com/2022/12/04/openvswitch-geneve-tunnel/

HomeSDN is back in business 😎#OpenVSwitch #FaucetSDN

@projectdp I really enjoyed the #SDN stuff, and using #OpenvSwitch. It was neat to learn, and think about how it could all be utilized with something like #PacketFence.

Hopefully you enjoy the Gluu stuff. I think it's great!

I think the biggest issue with maintenance, was that the systems generally sat idle or barely utilized, unless I was playing with something super complex. So, running them mostly idle, and then having a high performance enterprise class drive fail... well, it was $300-400 to replace a relatively small drive. But, they were 15k spinny drives rated for datacenter.

I had a power supply fail, and so replacing those were expensive. Fiber card failures, etc. General things that just fail from age. Which would be fine if I was utilizing it for something big. But, just having it sit there, running a windows domain with 1 or 2 users, full exchange setup, etc... neat, but not worth the overall cost.

Noise, heat, and all that wasn't too bad, because it all sits in a dedicated full server rack in the garage. Nice 2x 10Gbps fiber to the rack from main network stack.

If I was going to do a lab now, I'd probably utilize something similar to a NUC. Something relatively small / lower power, but can be loaded up with 128GB RAM minimum, and an okay processor. This would be more than enough for testing things.

These days, most of my lab work is done via a #digitalocean instance. Relatively cheap for what it is. Let's me explore, have a routable IP, etc. Then, I can shut it down if I want.

Optimally, maybe a small NUC + DO would be a good setup.

OK. Effectivement c'était bien "juste" un problème de MAC address lié au passage en bullseye...
Maintenant faut que je trouve pourquoi j'ai plus de bridge #openvswitch (peut être la même erreur ?)

RT @zwindler@twitter.com

Des gens arrivent à faire des bridges avec #ProxmoxVE 7 ?
Depuis l'upgrade, dès que j'assigne ma carte réseau comme port du bridge, je me coupe la chique.
Impossible de démarrer un bridge, qu'ils soit classique ou bien #OVS
😒😢😡
