The bug seems to be an improved version of bug #12222. There you couldn't restore a VM. Now you can't even start it.
A workaround is to stick with version 4.2.20 that works perfect.

You can fix your VM by executing
VBoxManage modifyvm "MS Windows XP" --longmode off
We have to check how we can fix such busted VM configurations automatically.

Hello Frank,
Your workaround has worked and I was able to boot the VM, but apparently bug #12222 hasn't been fixed, as a restore attempt on a saved VM session produced the following error:
Failed to open a session for the virtual machine MS Windows XP.
Failed to load unit 'PATM' (VERR_SSM_STRUCTURE_MAGIC).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}
back to 4.2.20 again, which seems to be the only workaround.

I have been tracking a 'PATM' VERR_SSM_STRUCTURE_MAGIC error in VirtualBox 4.3.4:

No response yet from Frank or Oracle dev team. :-/

Jacob,
It looks like a duplicate of bug #12222. It has been re-opened twice. We are waiting the next release that might fix our issue. Let's keep the present issue only for the VM start issue, when VT-x is not enabled and the config reports longmode on.

The SSM issue is really a duplicate of #12222, the initial report in this ticket is not.

- Status changed from new to closed
- Resolution set to fixed
The initial issue should be also fixed with VBox 4.3.6.

Confirmed on many old Windows and Linux Guests. It works fine.

Don't know if the fix in 4.3.6 covers all variants of this issue. At least my Win XP guest still runs in the SSM error, c.f. Zulu.log
