Proc: Phenom II X6 1090T 3.2GHz, BIOS Dell vA06

N/W: VirtualBox Host-Only Ethernet Adapter
RAM: 2GB, DDR3
HDD: Virtual Drive.
It works, but not stable. Mouse is sluggish. Straight VGA; DP2 Finder can be a little cranky. Running 4 CPUs for the heck of it. A lot of times will be entering text in a box and the window freezes. If I try to open up a picture, an icon opens up at the bottom and bounces, but clicking on it does nothing to change the state. Other things include the hard drive icon not showing up until DP2 Finder is launched (unlike its presence in SL).
Took me probably three days to get this working; required Googling till my fingers were numb. But now I've got a much better feel for what's going on here; blunt force iterating-it-to-death is usually the best way to know the in's and out's of the system.
if you do not see hdd drives in desktop make sure you have checked this in finder preferences menu , if you run lion in a virtualizer system it can be more unstable and lags , prefer a native system install ! good luck , the system work nice for me ( in 32 bits mode off course ...)
