"KVM and XEN image" is

https://download.opensuse.org/distribution/leap/16.0/appliances/Leap-16.0-Minimal-VM.x86_64-and-xen.qcow2

but should be

https://download.opensuse.org/distribution/leap/16.0/appliances/Leap-16.0-Minimal-VM.x86_64-kvm-and-xen.qcow2

"MS HyperV image" is

https://download.opensuse.org/distribution/leap/16.0/appliances/Leap-16.0-Minimal-VM.x86_64-HyperV.vhdx.xz

but should be

https://download.opensuse.org/distribution/leap/16.0/appliances/Leap-16.0-Minimal-VM.x86_64-MS-HyperV.vhdx.xz

All other links are wrong as well.
