We recommend to exit BOINC before powering off the computer, because the VBox Wrapper will capture that exit signal, and will try to save the virtual machine and avoid canceling the WU. This is not necessary when suspending or hibernating the computer.

VBoxWrapper does not support more than 1 core currently. We recommend you run multiple BOINC tasks, each with a single VM, to use multiple cores on your system.
