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.

You know that each vendor has customized image that includes VMware ESXi, drivers and management tools. It seems, there is an issue on HPE Agentless Management (AMS) on latest ESXi image.
QEMU (short for Quick Emulator) is a free and open-source emulator that performs hardware virtualization. QEMU is a hosted virtual machine monitor: it emulates the machine’s processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems.
All VMware guys know that guest OS needs drivers for
paravirtualized devices and the drivers provided by VMware as a package which called VMware Tools. VMware Tools is available for supported operating systems and also there is an open-source which called Open-VM-Tools and it’s available for modern Linux distributions and installed by operating system installer.

Whether you want to provide Ceph Object Storage and/or Ceph Block Device services to Cloud Platforms, deploy a Ceph Filesystem or use Ceph for another purpose, all Ceph Storage Cluster deployments begin with setting up each Ceph Node, your network, and the Ceph Storage Cluster. A Ceph Storage Cluster requires at least one Ceph Monitor, Ceph Manager, and Ceph OSD (Object Storage Daemon). The Ceph Metadata Server is also required when running Ceph Filesystem clients.
Software-defined storage (SDS) enables users and organizations to uncouple or abstract storage resources from the underlying hardware platform for greater flexibility, efficiency and faster scalability by making storage resources programmable.
