Hi,

after saving the virtual machine state same houres ago, now i'm getting this error when i'm trying to start the virtual machines (Windows XP)

Unknown error creating VM (VERR_GENERAL_FAILURE).
VBox status code: -1 (VERR_GENERAL_FAILURE).

Komponente:

Interface:
IConsole {1dea5c4b-0753-4193-b909-22330f64ec45}

I thought that some settings were may be corrupt, i tryed to change it... But then i got these error:

Assertion failed: [VBOX_SUCCESS (vrc)] at '/home/vbox/vbox-1.5.0/src/VBox/Main/MachineImpl.cpp' (4681) in nsresult Machine::openConfigLoader(CfgLoader**, bool).

After a second restart of the VM main program, it says that the machines i mentioned is "inaccesable": {{{Could not load the settings file '/home/freddy/.VirtualBox/Machines/Windoof XP/Windoof XP.xml' (VERR_OPEN_FAILED). FATAL ERROR: Duplicate unique value declared for identity constraint of element 'Uart'. Location: '/home/freddy/.VirtualBox/Machines/Windoof XP/Windoof XP.xml', line 302, column 88.}}}

In the 302th line in the file above stands: <Port IOBase="0x3f8" IRQ="4" enabled="false" hostMode="Disconnected" slot="1"/>

After deleting the line, saving the file and restarting the VM main program everythings working again...

Only when i'm not discarding the saved machine state i'm getting this error:

VM cannot start because the saved state file '/home/freddy/.VirtualBox/Machines/Windoof XP/Snapshots/{a2a10063-0e77-4933-8872-3f031d8efd2d}.sav' is invalid (VERR_FILE_NOT_FOUND). Discard the saved state prior to starting the VM.

Please could you retry with 1.5.4? Which host OS are you using?
