9.14. Configuring the custom ACPI table

VirtualBox can be configured to present an custom ACPI table to the guest. Use the following command to configure this:

VBoxManage setextradata "VM name"
      "VBoxInternal/Devices/acpi/0/Config/CustomTable" "/path/to/table.bin"

Configuring a custom ACPI table can prevent Windows Vista and Windows 7 from asking for a new product key. On Linux hosts, one of the host tables can be read from /sys/firmware/acpi/tables/.
