Creating an Optimized Windows Image for a VMware Horizon Virtual Desktop | VMware
system image are much different if you plan to deploy virtual desktops
rather than physical desktops:
- Physical desktops – Resource usage on a physical
machine impacts only the user who is using that machine. The operating
system on a physical machine determines whether or not resources are
available. One-time actions impact the user only the first time they are
performed because the machine is never refreshed. For example, a user
typically gets a new user profile the first time they log on, and they
continue to use that same profile with all subsequent logons.
- Virtual desktops – In contrast, in a virtual
environment, the guest operating system behaves as if it has exclusive
access to the CPU cores, but in reality the cores are shared between 2
to 8 virtual machines. When using nonpersistent VMs or user profiles,
the actions that are intended to run only once could run every time a
user logs on.
Therefore, with virtual desktops, one-time system actions must be
configured in the base image, and one-time user actions must be
configured in the default user profile. In addition, to reach a higher
consolidation ratio, increasing the number of VMs hosted on a single VMware vSphere® host, VMware recommends turning off features that are not needed.
