From the log I can find below messages which might cause in proper shutdown of the VM ,an inability to properly allocate the video RAM, if I'm not wrong.
Vix: [1153079 mainDispatch.c:3870]: VMAutomation_ReportPowerOpFinished: statevar=0, newAppState=1871, success=1 additionalError=0
Can you please try increasing the video RAM as mentioned in below KB and check how it goes.
