Windows 2012 R2 Standard installation failed under VirtualBox

[Peter Ross]

Hi,

I have a problerm to install Windows 2012 R2 Standard. I am starting using

VBoxSDL -startvm WindowsVM

It freezes after a short period with messages seen below.

VirtualBox is version 4.3.18..

I cannot chose as VM OS Windows Server 2012 so I take 2008.. but I found 
it mentioned as supported on the VirtualBox website for version 4.3.18.

In the VM you see:

Your PC needs to restart.
Please hold down the power button.
Error Code: 0x 000000C4
Parameters: 0x 00000000 00000091
             0x 00000000 0000000F
             0x FFFFF800 58FCEA00
             0x 00000000 00000000

On the console I have:

Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT)

Skipping ring-0 registers and styack, rcErr=VINF_EM_TRIPLE_FAULT.

Update: I installed virtualbox-ose-4.3.20_4 and new world and the problem 
still persists.

Any ideas?
