I've been using Vagrant installed with zypper from here:
https://download.opensuse.org/repositories/Virtualization:/vagrant/openSUSE_Leap_15.0/

The latest update is broken, rendering vagrant unusable:

sudo zypper -n in vagrant
vagrant plugin install vagrant-vbguest

Installing the 'vagrant-vbguest' plugin. This can take a few minutes...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

conflicting dependencies fog-core (~> 1.43.0) and fog-core (= 2.1.2)
  Activated fog-core-2.1.2
  which does not match conflicting dependency (~> 1.43.0)

  Conflicting dependency chains:
    fog-core (= 2.1.2), 2.1.2 activated

  versus:
    vagrant-libvirt (> 0), 0.0.41 activated, depends on
    fog-core (~> 1.43.0)
