Introduction to Linux interfaces for virtual networking | Red Hat Developer [2018-10-22]
Get an introduction to Linux virtual interfaces, including commonly used interfaces, when to use them, and how to create them.
Do you use any of the mentioned virtual network interfaces? What for?
Handy primer, but also out of date, especially for RHEL and RHEL-adjacent. For one thing, they’re all in on NetworkManager. The commands outlined in the article aren’t permanent, and it doesn’t go over ways to make them permanent. Secondly, teaming is deprecated by RH since the guy who maintained the driver quit.
Do you happen to know any more recent documentation that would have similar diagrams?
I don’t. I usually search for, e.g., nmcli bridge setup
I use macvtaps in my homelab for vulnerable VMs because no matter how I set up the bridges or what guide I followed it just broke networking every time on a headless server that's a massive pain to fix.
Wish I knew about macvtaps from the get-go, it was a dead giveaway that bridges are some demonic shit on Linux as every guide was different, and for every guide there was always some people on Reddit saying how it didn't work for them at all.
I haven't found myself missing hard-corpo software in a while but in that moment I really wished I was just using VMware on windows where creating a bridge interface takes one click instead of janky virsh syntax and messing with ifconfig etc.
