You have a hardening problem. Please read
really carefully the following FAQ:
Diagnosing VirtualBox Hardening Issues for some generic guidelines/ideas. Remember, these are guidelines, not the exact solution, you have to use your judgement as to which program might be responsible... I'd start by downloading and (re)installing the NVidia drivers.

It's a good habit to eject your Guest Additions (GAs) ISO when you're done with the GAs installation.
00:02:33.875470 VMMDev: Guest Log: VbglR0HGCMInternalCall: vbglR0HGCMInternalPreprocessCall failed. rc=-54
You have a gazillion of those, and I don't know why. Did the GAs install correctly? Can you install them again and watch the output of the process? Even better record it? Because failing in the HGCM, that's the Host-Guest Communication Module
(Maybe "Manager"? Something along those lines anyhow). Something's not right...
