XP systems upgraded from 6.1 to 7.0.2 fail to boot => fixed in SVN/next 7.0.x maintenance

[normanb2]

XP guest systems upgraded from virtualbox host 6.1 to 7.0.2 fail to boot until Version changed from 'Windows XP (32-bit) to 'Other Windows (32-bit)'. After changing Version to 'Other Windows (32-bit)' they all booted OK and performance seemed to be unaffected. Before changing the Version each system failed to find any boot disk.

Please upload a VBox.log of both VM runs (one from the failing and one from the succeeding run).

The 6 'Log of boot failure' files are identical. Sorry my browser appeared to be unresponsive. The VM is a freshly imported ova of XP freshly exported from a VM running without issue on 6.1.40. The imported VM booted OK after I had changed Version to 'Other Windows (32-bit)'.

We reproduced the issue and a re investigating this. As a temporary workaround you could run the following command:

VBoxManage setextradata <VM name> "VBoxInternal/HM/TPRPatchingEnabled" 0

That should make it work even with the correct guest OS type.

This will b fixed in the next maintenance release of VirtualBox, thanks a lot for the report!

I've tested the workaround and it works OK. I would also be interested in testing the fix but I don't know how to find the diff in svn.

VirtualBox 7.0.4 was just released and available for download at https://www.virtualbox.org/wiki/Downloads. This issue should be fixed in this version.
