Ask questions in GitHub Discussions
If you still could not find a solution, if you have interesting use cases, if you have custom configurations, and generally if you have any experience that you want to share with others, use the GitHub Discussions, and enter a New discussion in the Q&A category.
Register a new support ticket only if necessary
If you are convinced that you identified a bug related to the binary distribution, not QEMU itself (if you have doubts, use the GitHub Discussions), or you have a pertinent suggestion how to enhance the xPack QEMU Arm distribution, register a New Issue in the the GitHub Issues tracker.
Use of private e-mail
Sending private messages will be automatically replied with a link to this page. The reason for this rude behaviour is simply an attempt to use the time more efficiently; since discussions are archived, other people having similar problems might benefit from the answers.Edit
