Hi everyone, quite exhausted at this point. I have a 2018 Macbook pro laying around collecting dust. And no one will buy it from me, considering what a crappy machine it is by today's standard. It has 32GB RAM, a radeon Graphics card and a 2.9 gigahertz processor. I figure this would be a great...

Hello Forum I have searched the forum for an answer for about a month now, but I am unable to find one, or a similar solution to my problem. Recently I made the decision to migrate to Proxmox as hypervisor after using VMware since 2012. It goes very well. I’ve got an LXC container running and...

Hello. Is it possible to change Native vlan to something else than 1? If so, just globally, or is it possible to make it per VM?
