XHCI error when launching Virtual Box 5

[kjhoran]

Hi

I have recently upgraded to VB 5 and installed the relevant extension pack.

When launching the app today i get the following error:

Error in /Users/karlhoran/VirtualBox VMs/Windows 8/Windows 8.vbox (line 68) -- Invalid value 'XHCI' for Controller/@type attribute.
/Users/vbox/tinderbox/4.3-mac-rel/src/VBox/Main/src-server/MachineImpl.cpp[731] (nsresult Machine::registeredInit()).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
Machine
Interface:
IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

I have used the vm's since updating and they worked ok, although i did change a USB3 setting. I am unsure what to do.

I wasn't able to find the /Users/vbox/tinderbox directory.

Can anyone advise me please?
Cheers.

The issue seems to be that after installing VB5, the app was still running as 4.x

After reinstalling 5, all is well.

It's not at all clear what you did, but the above is a clue. Somehow you had a VM configured for VirtualBox 5.0 (the 'XHCI' attribute) but you ran it in VirtualBox 4.3 (that's what the "4.3-mac-rel" signifies). So the error as such is expected (4.3 doesn't support xHCI) but how you got there is not obvious. If you know what exactly you did, it'd be good to know.

Just remove the 'XHCI' line 68 and the controller found on top and below of the line in you Windows 8.vbox file your virtual machine should work normally
