How to reinstall KVM server and KVM tools ?

So installation of KVM and virt manager goes like Yast> Install hypervisor and tools> and selecting KVM server and KVM tools. How do i completely remove both and make a fresh re install again (as i dont know what all packages selecting these two packages install) ?

You can do a “force install” of any packages in openSUSE which over-writes everything, in particular default configuration files (by default and regular installation will attempt to re-use any existing configuration files which might have been customized by the User)
