''هسته مجازی'' DragonFly توسط هسته میزبان از طریق [[فراخوان سیستمی|فراخوان]] سیستمی جدید پشتیبانی می شود که به مدیریت فضای آدرس حافظه مجازی ( '''vmspace''' ) کمک می کند - <code>vmspace_create()</code> ، {{R|Dillon2006|lwn-2007-04|vmspace…}} و همچنین برنامه های افزودنی برای چندین فراخوان سیستم موجود مانند <code>[[mmap]]</code> 's <code>madvise</code> - <code>mcontrol</code> . {{R|lwn-2007-04|mcontrol.2|syscalls.master}}
