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?

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:

Hello LnxBil
Thanks for the information.
Have you experienced any difficulties using Oracle Linux (such as running Oracle DB)?
