OpenNebula Apps 7.4.2

We're excited to announce the release of OpenNebula Apps 7.4.2, the companion release to OpenNebula 7.4.2. This is a maintenance release that brings SSH key management improvements and several fixes to Linux contextualization, refreshes the base operating system images (including the new Fedora 45), and extends the service appliances with the new Open OnDemand appliance, a GRE module for the Virtual Router, and InfiniBand and NFS support for OneSlurm.
