so it is. it have working AES-NI.

I am such a kind of person that i am completely not on-time with 
marketing, namings, etc..

I just asked what CPUs will support AES-NI which is important for me (geli 
speedup) and got that in Dell Server ;)


Virtualbox works great with windoze on that machine.

i would rather bet on linux addon kernel modules you have to install.

In windows you have to install "guest additions" without this it is plain 
terrible.

Are you sure with two level pagetables featured in modern CPUs including 
sandy bridge?

for production - yes (6 instances of windows XP). Virtualbox does never 
make main workload for me, it is just addon. On FreeBSD 8.3.

But i've tried Windows 7 64-bit and it worked fine. didn't see any 
problems with latency you describe
