The installation method for a guest operating system (OS) within a virtual machine (VM) will depend on the available resources and the environment where the VM is hosted. Here are the three installation methods supported by vSphere 6 for a guest OS within a VM:
A. ISO image from the datastore: This installation method involves uploading the ISO image of the guest OS to the datastore accessible to the ESXi host where the VM resides. Then, the VM can be configured to boot from the ISO image to start the installation process.
B. CD-ROM: This installation method requires a physical CD or DVD drive on the host system that can be mapped to the VM. The guest OS installation media can then be inserted into the CD or DVD drive on the host, and the VM can be configured to boot from the CD-ROM drive.
C. ISO image from a Content Library: This installation method is similar to the first method, except the ISO image of the guest OS is stored in a content library. The content library can be a local library or a subscribed library from another vCenter Server instance. The VM can be configured to boot from the ISO image to start the installation process.
D. ISO image from an external FTP Server: This installation method involves downloading the ISO image of the guest OS from an external FTP server accessible to the ESXi host where the VM resides. The VM can then be configured to boot from the ISO image to start the installation process.
E. ISO image from Update Manager repository: This installation method is similar to the third method, but the ISO image of the guest OS is stored in an Update Manager repository. The VM can be configured to boot from the ISO image to start the installation process.
It's worth noting that the first three installation methods (A, B, and C) are the most common and are usually sufficient for most virtualization environments. However, vSphere 6 also supports the last two installation methods (D and E) for more specific scenarios where these methods may be required.
