This User's Guide explains the QNX hypervisor architecture and provides instructions for installing and running a QNX Hypervisor for Safety system, changing system components and configuration, and using hypervisor features such as virtual devices (vdevs).
For information about how to write your own vdevs, see the Virtual Device Developer's Guide and Virtual Device Developer's API Reference.
QNX hypervisors are available in two variants: QNX Hypervisor and QNX Hypervisor for Safety.
The QNX Hypervisor variant (QH), which includes QNX Hypervisor 2.2, is not a safety-certified product. It must not be used in a safety-related production system.
If you are building a safety-related system, you must use the QNX Hypervisor for Safety (QHS) variant that has been built and approved for use in the type of system you are building, and you must use it only as specified in its Safety Manual. The current QHS release is QNX Hypervisor for Safety 2.2.
Note that the information concerning the QHS and other safety-related components provided in this guide is for your convenience only. Refer to the appropriate Safety Manuals (e.g., the QNX OS for Safety 2.2.1 Safety Manual, the QNX Hypervisor for Safety 2.2 Safety Manual) for authoritive instructions on how to configure, start, and use your QNX safety-related components.
If you have any questions, contact your QNX representative.

This User's Guide includes and identifies as such documentation for some non-hypervisor QNX components that are of interest to QNX Hypervisor for Safety users but not described in the QNX Neutrino documentation.
The QNX Hypervisor Public Forum hosts technical notes and FAQs about different QNX hypervisor topics, and about building guests for a QNX hypervisor system and running them.
