About This Document
This User's Guide explains the QNX hypervisor architecture and provides instructions for installing and running a QNX Hypervisor system, changing system components and configuration, and using hypervisor features such as virtual devices (vdevs).
QNX Hypervisor for Safety (QHS)
QNX hypervisors are available in two variants: QNX Hypervisor and QNX Hypervisor for Safety.
The QNX Hypervisor variant (QH), which includes QNX Hypervisor 8.0, 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 latest QHS release is QNX Hypervisor for Safety 2.2, which is based on QNX SDP 7.1.
If you have any questions, contact your QNX representative.

Non-hypervisor components
This User's Guide includes and identifies as such documentation for some non-hypervisor QNX components that are of interest to QNX Hypervisor users but not described in the QNX OS documentation.
QNX Hypervisor GitLab Repository
The QNX Hypervisor GitLab Repository contains technical notes and FAQs about different QNX hypervisor topics, including building custom virtual devices and supporting guests for a QNX hypervisor system. The location of this repository is: https://gitlab.com/qnx/hypervisor.
The documentation about writing custom devices includes the Virtual Device Developer's Guide, which contains instructions and source code samples, and the Virtual Device Developer's API Reference, which describes the API for developing the devices.
