16305	Can't start session for virtual machine	coldshine		"I've got an error: 

'''Can't start session for virtual machine'''. 

The virtual machine 'MS DOS' has terminated unexpectedly during startup with exit code 1 (0x1).  More details may be available in 'E:\VirtualBox VMs\Machines\MS DOS\Logs\VBoxHardening.log'.

Erro code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}



Host - win 7, 64bit. Guest - any vmachine (tried msdos, win xp, win 7, ubuntu and got the same error).

BUT if I start the machine in the background session and then click show (or start background session with interface) - everything works!

Tested on 5.1.10, 5.1.8, 5.1.0 and test build (5.1.11). Seems like an issue with all 5.1.x versions.

Note that 5.0.x works fine on my host."	defect	new	other	VirtualBox 5.1.10				all	Windows
