Deploy OVA/OVF templates using OVF Tool

Recently I had massive problems with deploying some VMware appliances under vSphere 6.5. Independently of the frontend (Host Client, HTML 5 Client, Web Client, C# Client) I was unable to deploy templates in a clean way at all – mostly aborts and “generic system failures” occured. Mark Brookfield gave me the tip to use OVF Tool instead

Manage VMware Photon OS containers with Foreman and Red Hat Satellite 6

Photon OS is minimalistic RPM-based Linux distribution which is focussed on running Docker containers. It was optimized for VMware platforms (Workstation, Fusion, vSphere, vCloud Air) – e.g. its Linux kernel offers a caching mechanism optimized for vSphere. Another characteristic is the customized package manager tdnf (Tiny Dandified YUM) which is similar to YUM but has also supports managing OSTree content (git-like versioned kickstartable filesystem content).
