Ive been using VB for about 3 years no with no issues, now all the sudden Windows 8.1 (OSX HOST) keeps freezing after booting up and loading a program, it usually takes a second and i know it freezes when a green pixelated line shows up on top of the screen, not sure why?
log file says "HyperV: Guest indicates a fatal condition! P0=0x7a P1=0x6d2f58 P2=0xc000003f P3=0x48bb8880 P4=0xda5eb748" Attached is my Log file.
Please help, I need this for work as I use a Mac and require windows programs occasionally.
00:00:01.633108 GUI: 2D video acceleration is disabled
And so is the 3D acceleration. Shutdown the VM and enable them in the VM settings » Display. You'll also notice that the max VRAM will jump from 128 to 256 MB after that; max the VRAM as well. Then re-install the Guest Additions (GAs) in the guest. Speaking of GAs...
00:00:10.182862 VMMDev: Guest Additions information report: Version 5.1.6 r110634 '5.1.6'
You definitely need to keep up with the main VirtualBox program version.
I see what you're trying to do here... Since your host has 2 cores (not threads) and you've assigned both of them to your guest, you took the CPU cap to 87% (5/6). Not a bad idea, but not a well tested one either. Let's keep that in mind in case that something doesn't work/respond as expected.
You could change the USB settings to USB3, Win8.1 has native support for it.
Shut down the VM, make the changes, install the GAs. See if the situation gets better...

Ok, I made all the changes, updated guest additions and it seem to fix that issue, after boot-up it would run for a bit, then I would get bluescreen, did a little investigating and my CPU usage was spiking to 100% at times. Narrowed the usage down to Chromes Software Reporter Tool . Removed it and things seem to be running smoothly.
Hopefully all is well now, thank you for all the help.

Glad you finally got it going. Marking as [Solved].
