# Installation  

The disk controller has to be configured as IDE. Neither SATA nor SCSI are
supported.

The network controller should be configured as PCnet-PCI II or PCNet-FAST III
for instance. INTEL PRO or Paravirtualized Network do not work.


## 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


# Performance

If [[QEMU with KVM|qemu]] is not available, VirtualBox reportedly has better
performance.

    <youpi> I don't know what virtualbox does with hardware emulation, but
      gnumach is awfully slow to probe things there
