Physical / Virtual Computer Type Analysis - Improved
| 0 Votes |
Description
|
This Analsyis will determine for a given computer whether it is physical or virtual. Since this information does not change much, these properties are only evaluated once per day. |

| Looking at this again, I think I'm going to try 'bios as string contains "VMW"' to identify Virtual Machines running OS X. | |
 |
|
| Something like this seems to be the best method. Not sure if this specific relevance is the best option though. | |
 |
|
| Is this still the best (or only) way to determine if the endpoint is physical or virtual machine? | |
|
|
| The computer type is not session relevance. Something wrong with the detection of that in BigFix.me which may be made worse by all my comments in it. | |
