I think it would be better to answer this question that it would to attempt to answer the VirtualBox question (I run it on a 64-bit OS, so I can't really answer that anyway). The benefit to running ZFS on a 64-bit OS is if you have a large amount of RAM. I don't know what the breaking point is, but I can definitely tell you that a 32-bit kernel and 4GB ram doesn't mix well. If all you are doing is testing ZFS on VMs you probably aren't all that worried about performance so it really shouldn't be an issue for you to run 32-bit. I'd say keep your RAM allocations down, and I wish I knew what to tell you to keep it under. Hopefully someone who has a better grasp of all that can chime in. Once you put it on real hardware, however, you really want a 64-bit CPU and as much RAM as you can toss at the machine. -brian -- "Coding in C is like sending a 3 year old to do groceries.
