VMware Photon OS – Best OS for Kubernetes and Container Host

During virtualization revolution, IT administrators was be able to use single physical host as virtualization host and providing compute resource for multiple services. Now IT world is going forward and companies moving their services to Cloud-Native Application or Container. Compared known Virtualization and OS Level Virtualization, using less storage capacity is the biggest benefit of OS Level Virtualization or Containerization. Most known Hypervisors are not made for OS Level Virtualization and Containerization needs Container Host. Container Host can be a known Operating System such as Linux distributions.

Guest Operating System Upgrade or New Virtual Machine?

Virtual Machine needs guest operating system (OS) to operates same as physical machine. Operating system is a system software and has life cycle same as other software. But what should we do about updating and upgrading guest operating systems in virtual environments. Guest Operating System Life-Cycle Most implemented services don’t need to any new features on operating system, so we should choose guest operating system with long term support. Both Windows and Linux (Some distributions) offering different of channels. You can choose a path that more stable or choose a path for have new features. Update vs Upgrade When you need to newest technologies and features on the latest major version of operating system, you have to do Upgrade. But when you are applying regular patches on operation system, you are doing Update. Keep Update Guest Operating System Operating systems’ vendors releasing patches during operating system life-cycle. Apply patches (Security or others) to keep guest operating system secure and stable as well as your services and business.

We have many HPE Blade System C7000 chassis for hosting our virtual infrastructures or our customers virtual infrastructures. Also many of them are filled with HPE ProLiant BL460c Gen10. Recently, we had serious problem with some of the servers about network connection, if there was FlexFabric 650 (FLB/M) adapter installed on blade server. What’s Exact Problem? Our servers were working fine but after a while, we lose our vMotion network connectivity, the hosts couldn’t migrate virtual machines even between servers in same C7000 chassis. The problem was happened on one chassis and other chassis has no problem. Network adapter was connected physically but it don’t pass any network traffic, the issue some like ARP problem! Also network adapter status was Degraded in iLO web administration. List of All Attempts to Recovering Issue Try this, ask IT guy about network problem on network card, one hundred percent sure that IT guy will say: Upgrade firmware, update driver, upgrade ….! So, I did it! 😀 Let’s review the list: Upgrade Firmware for FlexFabric 650M and FlexFabric 650FLB. Update Driver (ESXi). Turn off, turn on virtual connect modules. Unassign and reassign server profiles. Check all configurations and compare with other chastises. Re-seat one...
