Quite some KVM related work has been done today.
Moved "xml does not validate" to answered questions and disabled xml validation in Whonix's build script.
really confusing. Users tend to mindlessly copy and paste commands. No offense, since in the flood of information, sometimes happens to me as well. Just want to adjust the documentation we have to the users we have and not to the users we wish we had. I strongly believe in "anything can go wrong, will go wrong" - talking from experience with previous Whonix support. And every support request, eats up development time. So I wish KVM to cause as little support requests as possible.
Therefore I think it is best if we recommend to use an arbitrarily chosen default folder to store Whonix images. Such as the user's home folder ~/. Then users who did that can mindlessly copy and paste the commands and will not create support requests due to wrong paths.
And to suit the more experienced users as well, we can just add a footnote such as "These are example paths so less experienced or less attentive users can mindlessly copy and paste these commands. If you are an advanced user, feel free to download Whonix to a custom location." I guess this is best to make both groups of users happy.
