Are you using Virt-Viewer or Virt-Manager?
If you are using Virt-Manager, create SSH password less login between the 2 machines and try again.
Also how many times does it prompt for root password when you first connect to the VM ?
And what OS are you using for Virt-Manager ?
The VM doesn't existyet. There is no keyboard available during the process of trying to install the operating system
And there is an option for key mapping in Virt-Manager, you can make it auto or en-US
I don't see any such option under Preferences, New VM
