| <div class="block">This interface provides information on whether the current Operating System is running directly on physical hardware |
| or running as a Guest (Virtual Machine (VM)/Logical Partition (LPAR)) on top of a Hypervisor. |
| If the Operating System is running as a Guest, the interface provides information about the Hypervisor. |
| <b>Where there are multiple levels of Hypervisor, only the top level Hypervisor information is returned.</b> |
| The supported Hypervisors and the platforms on which they are supported: |
| <ol> |
| <li>Linux and Windows on VMWare. |
| <li>Linux and Windows on KVM. |
| <li>Windows on Hyper-V. |
| <li>AIX and Linux on PowerVM. |
| <li>Linux and z/OS on z/VM. |
| <li>Linux and z/OS on PR/SM. |
| </ol> |
| <p>On some hardware, Hypervisor detection might fail, even if the Hypervisor and Operating System combination |
| is supported. In this case you can set an Environment variable - IBM_JAVA_HYPERVISOR_SETTINGS that forces the |
| JVM to recognize the Hypervisor. |
| <ul> |
| <li>For example: On Windows to set the Hypervisor as VMWare,<br> |
| set IBM_JAVA_HYPERVISOR_SETTINGS="DefaultName=VMWare" |
| <li>Other valid Hypervisor name strings (case insensitive): |
| <ul> |
| <li>VMWare, Hyper-V, KVM, PowerVM, PR/SM, z/VM. |
| </ul> |
| <li>If the actual Hypervisor and the one provided through the Environment variable differ, the results are |
| indeterminate. |
