# Installation
The disk controller has to be configured as IDE or AHCI. Neither RAID 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.

## IRC, freenode, #hurd, 2011-10-31
<youpi> I don't know what virtualbox does with hardware emulation, but
gnumach is awfully slow to probe things there
## IRC, freenode, #hurd, 2013-09-28
<snadge> the problem is if i giveit more than 1855 it says truncating to
that
<snadge> so i give it that.. then it has kmem alloc error
<snadge> 1536mb same.. 1024 isok
<braunr> hum
<braunr> that's weird
<braunr> virtual box ?
<snadge> yeah
<snadge> i wonder what cpu features i should enable/disable
<snadge> pae ?
<braunr> make sure vbox doesn't count on the so called memory balloon
<braunr> pae isn't used except on xen
<braunr> disable apic
<braunr> enable host io cache in disk controllers
<youpi> do we have these written on the wiki?
<braunr> no because i didn't run into these problems
<braunr> but since i know the system well enough to avoid them in the first
place ..
<braunr> we need real users to report them
<braunr> i'm not sure we have anything about vbox in the wiki actually
<youpi> ./hurd/running/virtualbox.mdwn
<youpi> we seem to have a page at least
<snadge> it seems to be okay with 1024MiB
<braunr> still weird
<braunr> looks more random than buggy with more memory
<braunr> do you have the exact error message you got during your previous
attempts ?
<snadge> no.. i should have taken a screenshot.. its easy enough to
reproduce though
<snadge> i'll wait until after its installed
