Ok, then should be very straightforward. You can port it, we will try to post the source code late next week. The majority of the src is cross platform, you only need to change the hooks to the kernel, in runtime.c. --- On Sat, 4/10/10, François Revol <revol@xxxxxxx> wrote: From: François Revol <revol@xxxxxxx> Subject: Re: [vbox-dev] Linux VHD Boot available - download and boot your physical pc, also runs as vm To: "Huihong Luo" <huisinro@xxxxxxxxx> Cc: haiku-development@xxxxxxxxxxxxx, vbox-dev@xxxxxxxxxxxxxx Date: Saturday, April 10, 2010, 9:24 AM Le Sat, 10 Apr 2010 09:01:37 -0700 (PDT), Huihong Luo a écrit : > That should be doable.

BeOS had an fmap driver which used block lists in the partition the image was, passed from the bootloader, to access it directly (without having to mount the containing filesystem). I started implementing a similar driver in Haiku but never finished. Something alike could be done, either as a vmdkloop driver publishing a device directly or as a partition_module which the device manager uses to then publish entries in /dev/disk/. François.
