virt facts: allow guest/host to have >1 virt tech (#70832)
Change: - Allow systems to declare multiple virt techs. For example if a system is both a docker container, but virtualized on KVM, show both. If a system is set up to run virtualbox and KVM VMs, show both. - This is done by introducing new facts keys: - virtualization_tech_guest - virtualization_tech_host - Backwards compatibility is preserved by keeping track of the previous return-points and refusing to update those keys after we would have returned, but now returning them at the end, so that the new keys can accumulate their data. Test Plan: - Local - CI Tickets: - Refs #66304 - Refs #17151 - Refs #17058 - Probably others Signed-off-by: Rick Elrod <rick@elrod.me>

* facts - ``ansible_virtualization_type`` now tries to report a more accurate result than ``xen`` when virtualized and not running on Xen.
|
||||
* facts - On NetBSD, ``ansible_virtualization_type`` now tries to report a more accurate result than ``xen`` when virtualized and not running on Xen.
|
||||
* facts - Virtualization facts now include ``virtualization_tech_guest`` and ``virtualization_tech_host`` keys. These are lists of virtualization technologies that a guest is a part of, or that a host provides, respectively. As an example, a host may be set up to provide both KVM and VirtualBox, and these will be included in ``virtualization_tech_host``, and a podman container running on a VM powered by KVM will have a ``virtualization_tech_guest`` of ``["kvm", "podman", "container"]``.
