Had IO APIC turned on so that I could give the guest access to two cores. Also had VT-x turned on. The Virtualbox.exe started consuming all memory on my host system -- before I killed it, it had consumed about 700MB of memory (it usually sits around 100). Turning off IO APIC and VT-x seems to stop the Virtualbox.exe process from running away with the memory." defect closed other VirtualBox 3.0.6 worksforme memory, ubuntu Linux Windows
