I am running my HA on a Intel / Linux (Ubuntu 20.04.3 LTS) PC with Virtual Box.
Running Virtual Box version 6.26 & HA version 7 (7.2) works just fine, but after upgrading VB to version 7 , the HA guest will not start.
The error message I get is : 0x80004005 Machine Wrap… etc…
If I downgrade VB to 6.26 everything works just fine again…
I have tried a manual installation according to the detailed step by step installations I found here in the community by @Jelle_S & @Aephir but the problem remains.
(Installing the upgraded version of the VB extension pack makes no difference…, I still get the error)
Any ideas ??
