 * 在 Windows 平台上，讓 VirtualBox 直接使用實體硬碟(Physical Disk)的做法 ([wiki:jazz/10-07-20 2010-07-20])
   * [參考] [http://www.sysprobs.com/access-physical-disk-virtualbox-desktop-virtualization-software Access Physical Disk in VirtualBox- Desktop Virtualization Software]

}}}

 * Windows 上怎麼讓 VirtualBox Guest 的 port 穿透到 Host 來 - NAT 底下用 add port forwarding rule ([wiki:jazz/10-04-21 2010-04-21])
{{{
VBoxManage.exe setextradata "Ubuntu 9.04" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/Protocol" TCP
VBoxManage.exe setextradata "Ubuntu 9.04" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/GuestPort" 22
VBoxManage.exe setextradata "Ubuntu 9.04" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/HostPort" 8022

= VirtualBox on Linux =

 * [備忘] 把 Windows 變成 Linux 上跑的 VirtualBox Image ([wiki:jazz/10-07-20 2010-07-20])

}}}
 * [備忘] 把 Raw Image 變成 Linux 上跑的 VirtualBox Image ([wiki:jazz/10-07-20 2010-07-20])
   * [錯誤作法] 如果給 Raw Image 的話，會出現不是 block device 的訊息。因此要用 losetup 把 image 變成 block device
