This is a memo when I prepared an environment to use multiple same OS (Ubuntu 22.04) with WSL2 on Windows 11, referring to other web pages. The procedure is based on Windows 11 WSL2 with one Ubuntu 22.04 already installed.
1. Start Power Shell with administrator privileges and execute the following command.
PS C:\Users\username> wsl -l --verbose NAME STATE VERSION * Ubuntu Running 2
2. Execute the following command to export the OS environment (Ubuntu).
PS C:\Users\username> wsl --export Ubuntu Ubuntu-22.04.4.Copy.tar
3. Run the following command to import the exported OS environment with the name Ubuntu-22.04.4.Copy.
PS C:\Users\username> wsl --import Ubuntu-22.04.4.Copy Ubuntu-22.04.4.Copy Ubuntu-22.04.4.Copy.tar
4. Execute the command in step 1. again, and it will show the following output.
PS C:\Users\username> wsl -l --verbose NAME STATE VERSION * Ubuntu Running 2 Ubuntu-22.04.4.Copy Stopped 2
5. I confirmed that I can log in to the imported OS environment (Ubuntu-22.04.4.Copy) with the specified user name using the following command.
PS C:\Users\username> wsl -d Ubuntu-22.04.4.Copy -u username
6. Sets the default login user name in the OS environment (Ubuntu-22.04.4.Copy) for the next time the imported OS environment (Ubuntu-22.04.4.Copy) is launched. Add the following highlighted line to /etc/wsl.conf using a vi editor, etc. In the example below, the user name is username.
username@ESPRIMOWD2H2:~$ cat /etc/wsl.conf [boot] systemd=true [user] default=username
7. I confirmed that the imported OS environment includes directories, files, etc. created in the exported environment as shown in the example below.
fukagai@ESPRIMOWD2H2:~$ ls /repos/ images yolov9 fukagai@ESPRIMOWD2H2:~$ sudo docker ps -a [sudo] password for fukagai: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0c38c2a0b984 nvcr.io/nvidia/pytorch:21.11-py3 "/opt/nvidia/nvidia_…" 14 hours ago Exited (0) 14 hours ago yolov9-gpu
8. The following command removes the OS environment (Ubuntu).
PS C:\Users\username> wsl --unregister Ubuntu
9. Memo
I wanted to reconfirm the procedure for setting up Docker to use NVIDIA’s GPGPU in an Ubuntu 22.04 environment, so I checked the procedure for running multiple operating systems of the same version on WSL2.
I confirmed that steps 1. through 7. allow us to back up the original OS environment.
The original Ubuntu 22.04 environment was removed in step 8. and Ubuntu 22.04 was reinstalled on WSL2 with the following command. The installed Ubuntu 22.04 is confirmed to be the environment immediately after installing Ubuntu 22.04, as shown in the example command below.
PS C:\Users\username> wsl --install
Ubuntu is already installed.
Ubuntu is running...
Installing, this may take a few minutes...
