Hi

I have the following issue when I will install a kvm VM system via the command, on an aarch64 system, and to use the same architecture as VM but

virt-install --name vm3 --memory 1024 --disk size=30 --arch aarch64 --debug --location http://download.opensuse.org/ports/aarch64/distribution/leap/15.2/repo/oss

but I got :

You should know that there is a difference between an installation source and the OSS repository…
The installation source contains the installation routine and optionally the files needed to install.
The OSS repository does not contain an installation routine and only has files used to build or maintain a machine.

So,
I’d recommend in your installation command to point to an installation source (typically an ISO file) and not to the OSS repository.
If you haven’t provided necessary info in your command (and there are many items), you will be prompted to provide those as the installation progresses unless a default is automatically entered (eg your number of processors).

Most people will download the ISO installation file and store it on your machine or network somewhere, and then configure your installation path accordingly. I haven’t tried to access an installation source from across the Internet as you’ve tried to do, and don’t know if there are consequences… At the least, I’d expect the entire ISO file (which can be multiple gigabytes in size) would have to be downloaded into your system RAM before it can be run if you did so…
