This will send an ACPI shutdown signal to the virtual machine, which has the same effect as if you had pressed computer. So long as the VM is running a fairly modern operating system, this should trigger a proper shutdown mechanism from within the VM. • Power off the machine: With this option, VirtualBox also stops running

This will send an ACPI shutdown signal to the virtual machine, which has the same effect as if you had pressed computer. So long as the VM is running a fairly modern operating system, this should trigger a proper shutdown mechanism from within the VM. • Power off the machine: With this option, VirtualBox also stops running on the host, when the guest is activated, it will be disconnected from the host without a proper shutdown. This may cause data loss. 2. Solaris hosts have a few known limitations regarding USB support;
