+About VirtualBox.
+=================
+
+  http://www.virtualbox.org/wiki/Guest_OSes
+                Guest OSes support status for VirtualBox.
+
+Copy and resize VirtualBox disk.
+--------------------------------
+
+I have clear copies of several OSes for VirtualBox. When I need new one I copy
+and resize them to get desired size.
+
+To copy I make a copy::
+
+  $ vboxmanage clonehd /path/to/Hurd.vdi /path/to/Hurd-new.vdi
+
+determine size::
+
+  $ vboxmanage showhdinfo /path/to/Hurd-new.vdi
+
+  UUID:                 63b87983-3130-4db3-cd8c-6d693dcfd92b
+  Accessible:           yes
+  Logical size:         2996 MBytes
+  Current size on disk: 1660 MBytes
+  Type:                 normal (base)
+  Storage format:       VDI
+  Format variant:       dynamic default
+  In use by VMs:        Hurd (UUID: f7591848-2c60-4c7c-3886-b66bdb35e425)
+  Location:             /path/to/Hurd-new.vdi
+
+and then apply new size (in MiB)::
+
+  $ vboxmanage modifyhd --resize 35000 /path/to/Hurd-new.vdi
+
+Next I mount ``parted-magic`` and boot to it and use ``gparted`` to extend
+existing fs to free space.
