We have upgraded AHV to 20160925.103, running on Dell XC430-4 harware (w/ Dell BIOS upgraded to 2.7.0) and have applied guest vm patches, however we would like to know if there is a supported method to ensure proper mitigation? Both the Microsoft provided Get-SpeculationControlSettings as well as https://github.com/vrdse/MeltdownSpectreReport/
suggest that we do not have hardware support, but I believe we do per required AHV and BIOS updates and instead the guest vms (we tried cold booting a few as well) are not able to read hardware details. We get "Default System BIOS" for the BIOS version and "System.Object" for CPU details...
Any thoughts / guidance would greatly be appreciated!
