Facter 3.9.2

Released October 2, 2017.

This is a bug-fix release of Facter and libwhereami that addresses potential fatal errors in the new hypervisors fact. Facter 3.9.1 was not publicly released.

Bug fix: Fix hypervisors fact resolution when run inside some Windows VMs

When running Facter 3.9.0 in virtualized Windows environments where Windows Management Instrumentation (WMI) values were only partially available, for instance on an OpenStack VM, Facter exited with a fatal unhandled exception: unable to get from empty array of objects error. Facter 3.9.2 resolves this issue.

Bug fix: Prevent failed fact resolutions from stopping Facter

In previous versions of Facter, a failed fact resolution could halt Facter. Facter 3.9.2 resolves this issue by displaying failures as warnings and continuing to resolve other facts.

Bug fix: Allow hypervisors fact to be blocked

The experimental hypervisors fact introduced in Facter 3.9.0 can cause Facter to fail in some virtualization environments. In Facter 3.9.2, you can block this fact in facter.conf.

Other bug fixes

  • FACT-1765, PA-1466: Don’t report warnings about a missing dmidecode component on Power8 systems, which don’t use dmidecode.

Facter 3.9.0

Released September 13, 2017.

This is a feature and bug-fix release of Facter.

Known issues

  • FACT-1749: The hypervisors fact introduced in Facter 3.9.0 can cause Facter to fail in virtualized Windows environments where Windows Management Instrumentation (WMI) values are only partially available, for instance on an OpenStack VM.

New Features

  • FACT-1742: Facter 3.9.0 adds a new hypervisors fact for virtualization providers that uses libwhereami, an optional new dependency enabled by default in Puppet Platform 5.2 builds of Facter.

    The new fact recognizes multiple hypervisors in nested virtualization environments, and includes metadata about each hypervisor where available. The hypervisors fact and libwhereami are the first steps toward improved virtualzation support in future releases of Facter. They also reduce its dependence on the external tool virt-what, which has a few detection bugs and requires root to run.

    This new feature should therefore also remediate discrepancies in Facter’s output when run as root and as a non-root user under virtualized environments.

Bug fixes

  • FACT-1728: Facter 3.9.0 provides an improved error message when facter -p is specified but Puppet cannot be loaded.
  • FACT-1731: Facter 3.9.0 correctly reports virtual and is_virtual facts when using FreeBSD’s bhyve hypervisor.
