The issue of 4GB versus 3.5 GB sounds like a 32-bit OS limitation to me.

32-bit operating systems can only address a maximum of 4GB; out of this however parts are not useable due to I/O addresses, BIOS adresses etc.

Generally 3.5 GB is considered a realistic maximum for a 32-bit OS.

So the question basically is: Is your domain controller using a 32-bit windows OS? If so, it might explain the issue you are seeing.

I just run in strange issue. I have domain controler that was assigned 2
gb of ram and I wanted to doulble it but then windows 2012 would not
start it just froze or started recovery and circle keep spinning. I went
down to 3.5 gb and it started no issues. I have six core amd system with
16 gb of ram. I have also installed windows 2012 standard on xen with
xeon 5520 and I was able push memory to 8 gb of ram. I am using xen
4.3.1-pre. The system that did not work had the latest xen git 4.3.1-pre
installed.

The OP stated that the guest OS is Windows 2012 which is 64-bit only.
