+## Converting from qemu image
+
+It is possible to convert qemu raw image to one of the formats recognized by VirtualBox, namely vdi format.
+
+If you are not sure if the image is a raw format, use qemu to get the information:
+
+ qemu-img info debian-hurd-original.img
+
+To convert the image you need the VirtualBox package properly installed with a VBoxManage tool (which is part of the package). Convert image from raw to vdi:
+
+ VBoxManage convertfromraw debian-hurd-original.img debian-hurd-converted.vdi --format VDI
