How to execute x86_64 binaries in Linux VM with Rosetta 2

Thanks to Apple's Virtualization framework it is possible to use Rosetta 2 inside a Linux VM to run x86_64 applications. All the videos and resources I've found online only explain how to install x86 applications using the apt package manager by appending :amd64 to the application name. For example:

sudo apt install libx11-6:amd64

You also need to add the amd64 apt repositories such as described in the Github repository macOS-Linux-VM-with-Rosetta . But I'm wondering, and I haven't found an answer yet, how to execute x86_64 binaries that I have manually downloaded somewhere or compiled on my own, not through the apt registry. I'm using Parallels 20.1.1 on an M1 Mac Pro running macOS 15.0.1, I have created a Ubuntu 22.04.2 VM with the Parallels Rosetta setting enabled. I have also enabled Rosetta in my VM using the script provided by Parallels as described in Using Rosetta to run x86-64 Docker Containers and Binaries in Linux virtual machines with Parallels Desktop .

$ sudo ./rosetta_x86_sources.sh enable
$ sudo apt update

But when I execute a x86 binary inside this VM I get an error indicating that I'm running the wrong platform.

cannot execute binary file: Exec format error

how can I execute x86_64 binaries on a Linux VM with Rosetta 2?
