I’ve been trying to create an image using packer-plugin-qemu and I consistently have failed results.
I am probably missing something obvious related to network.
This issue is quite common, just search for “Waiting for SSH to become available…”, it is the standard step which a build process hangs.
I am on a macos host.
I’ve tried it on ubuntu as docker container. same issue.
It hangs forever on Waiting for SSH to become available…
Does anyone has any tip on how to debug this ?
Here are some logs
