Creating or converting a VM to LXC

[Paulo F. Santos]

Olá Dev's, queria saber se é possível transformar uma VM em LXC? Se não, como posso criar um LXC com um sistema operacional (por exemplo, Oracle Linux)? Então, se eu puder montá-lo, disponibilizá-lo para a comunidade?

Hello Dev's, I wanted to know if it is possible to turn a VM into LXC? If not, how can I create an LXC with an operating system (e.g. Oracle Linux)? So if I can assemble it, make it available to the community?

It's not a PVE question per-se, yet it works perfectly fine. The easiest steps would be:

• boot a live linux inside of your VM
• tar the filesystem and store it "outside" of the VM and compress it with e.g. gzip
• use this file as a template for creating an LX(C) container

This is the easiest method, not the best. I would then further optimize it by removing stuff like kernel, grub and everything else boot related (e.g. efi stuff).

I'm running a couple of Oracle Linux VMs in various setup (e.g. including oracle database) for quick tests.

Here a couple of other threads about this:
