i've been using both Virtualbox and VMWare on Linux mint x64 for about 2 years now
i'll be switching to Lubuntu x86 pretty soon because i kinda broke my mint installation
How much difference would it make if i take a 32bit host?
im on a 6core with 8 gigs of ram, (3,2gb ram, 4cores to the guest) i just play some games in my vm, some recent games as well (but they run stable, so im happy)
im taking a 32bit host because i can fit Lubuntu 14.04 x86 on a CD, i dont have nay dvd's left (and i dont feel like buying some)
