For some reason 1/2 stuck in my head as the max, but I'll believe you. :-)

I'm not sure how much overhead virtualbox has, and you didn't say what
else was running on the system at the time.

Did you check how much memory the ARC and other applications were
using during the install? You can find the size of the ARC with kstat
by looking at the zfs module (kstat -m zfs).

Again, what else was running, and what was the size of the ARC?
