Supported Guest Operating Systems

The vSphere Guest API software runs on most Windows or Linux guest operating systems supported by the various versions of ESXi.
See the
VMware Compatibility Guide
for a list of supported guest operating system versions. This guide is now located at http://www.vmware.com/resources/compatibility in Web format.
The Guest API does not support the following guest operating system environments:
  • Windows 95 and Windows 98.
  • Windows NT 4.0. For Windows NT 4.0 you must use Guest SDK 3.5, which you can find by going to http://www.vmware.com/support/developer/guest-sdk and selecting an old release.
