Here is what I have in my terminal right now and I don't quite understand what is going wrong. It appears that the command Virsh cannot find the gateway .xml file.
asdf@asdf-VirtualBox:~$ sudo virsh -c qemu:///system define Whonix-Gateway*.xml
error: Failed to open file 'Whonix-Gateway*.xml': No such file or directory
The .xml is sitting in my downloads folder, and i tried moving the directory to the downloads folder but the same thing happened. Also if it helps I'm pretty much following the guide step by step(https://www.whonix.org/wiki/KVM). This issue is probably has more to do with my lack of understanding of KVM than it is an error or a bug but nonetheless it is stopping my progress.
