Hi, just had a look at Bug 1501761 <https://bugzilla.redhat.com/show_bug.cgi?id=1501761> - Add the additional host to the HostedEngine failed due to miss the package "qemu-kvm-tools" Issue is that since qemu-kvm-tools has been removed in recent qemu-kvm we dropped it as requirement in 4.2 so it's not included anymore in oVirt Node 4.2.

- Is oVirt Node 4.2 supposed to be backward compatible with oVirt Engine 4.1?

If so, we need to change ovirt-host-deploy in the upcoming 4.1.7 release in order to not fail when adding a 4.2 node.

It can be delivered in 4.1.8 ...​

Fortunately no changes will be needed on engine as host upgrade manager in 4.1 checks only about qemu-kvm and qemu-img​ ​packages​ ...
