14512	Windows XP guest OS does not start	John Rose		"I'm using Ubuntu Trusty. Under VirtualBox 4.3.10_Ubuntu R93012, my other OSs (e.g. Debian, openSuse) startup OK. However, Windows XP (my only Windows OS) starts up OK but then displays a window with details of NS_ERROR_FAILURE (0x80004005).

Carried out install of VirtualBox 5.0.2 from LocutusOfBorg's ppa (https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/locutusofborg-ppa/). Once I'd removed old Extension Pack & installed Extension Pack 5.0.2 from Oracle's site, Windows XPp & other guest OSs started OK.

It's OK on my desktop as detailed above. However, I've just tried the same updates on my laptop. It installs VirtualBox 5.0.2 & its Extension Pack OK. However, starting Windows XP gives a slightly different error:
Failed to open a session for the virtual machine WindowsXP.
Unsupported version 56 of data unit 'PATM' (instance #0, pass 0xffffffff) (VERR_SSM_UNSUPPORTED_DATA_UNIT_VERSION).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

PS this is logged on Launchpad (for Ubuntu) as bug 1489279"	defect	new	other	VirtualBox 5.0.2		Windows XP		Windows	other
