Interface ('VirtualBox Host-Only Ethernet Adapter #2') is not a Host-Only Adapter interface (VERR_INTERNAL_ERROR).

[ManWithNoName]

1) Context Virtual Version : v5.1.22 Host : Windows 10 Guest : Debian v8.7

2) Problem description : An error message appears when starting my Guest.

3) Error Message : Interface ('VirtualBox Host-Only Ethernet Adapter #2') is not a Host-Only Adapter interface (VERR_INTERNAL_ERROR). Code d'erreur : E_FAIL (0x80004005) Composant : ConsoleWrap Interface : IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

4) Usefull infos : I suspect that the problem was appeared when I have updated VirtualBox from v5.1.10 to v5.1.22 The host only network adapter was #2 and now as you can see in screen shots this is the #3. So I suspect there a "binding" problem between #2 (old version of VBox) and #3 (new version of Vbox) Is there new network devices between v5.1.10 and v5.1.22 ? Is the default network device for my Host was changed ?

Best Regards

Workarround solution :

Guest Settings -> Network : First, disable the Host-Only Adapter and valid. Then, enable again the Host-Only Adapter and valid.

I think, it synchronize the adapter number.
