I've done some searching around, but I just wanted to get confirmation on this...
What do I need in order to choose an x64 OS in Virtual Box? VT-X? VT-D? Is the AMD equivalent AMD-V? And if I need a new motherboard, where would I search to see if it supports these technologies? Right now I have a Q8300 and an ASUS P5Q3. According to ASUS this board does not support VT-X. I ran the Intel check tool, but I'm not sure if the board has something to do with it telling me there's no VT-X support.
OS is Server 2012.

Re: X64 OS not a choice
The requirements are described in the user manual. For Intel it's VT-x and for AMD it's indeed AMD-V but all recent AMD chips have this feature. Sometimes the feature is available but disabled in the BIOS so you might check your BIOS settings first.

Re: X64 OS not a choice
You must also make sure that nothing else is already using VT-x/AMD-v. On a Win2k12 host that means: make sure Hyper-v is disabled.
