I tried a lot, but a program didn't work in lxc. (multics r82 , r83, r84) R81 works fine but r82+ does not work. Now can I go back to openvz? The source code is here. github.com/multi-cs/multics I'm sorry for my bad english.
I am not have a subscription. Can subscription solve this problem? I'm thinking of going back to Proxmox 3 or using solusvm vss. Because I don't think I can solve this problem.
OpenVZ is not supported since PVE 3.x, but having a subscription has nothing to do with it, it is only for commercial support and doesn't add any features to the software, since it's completely free to use anyway Most probably your problem occurs because of something in the software you're using. Maybe if you provide us the error, we can get closer to a solution. Where does it occur exactly? At your position though, I would ask them why this specific version you want is not working with LXC, and maybe we can figure out a solution based on their answer.
We are also still using PVE 3.4 with OpenVZ as almost everything is just working. Tried to move to LXC but was a painful experience - with 10 years of OpenVZ we didn't had that much issues and downtimes than 3 months with LXC, so we stay running the productive environment with OpenVZ. We also have one 2 Node cluster with PVE 5.4 for testing but LXC is not really usable in an production environment - virtualization normally simplifies your infrastructure but with LXC it's the other way around, better to go with KVM. The PVE gui is great where i find the old gui better and more usable with the horizontal menu as the new one in the middle - would be cool if there is a option to choose between themes...
