Pambuyo posanthula polojekiti ya OpenBSD yotulutsidwa Malangizo zofooka mu VMM hypervisor, kudziwika sabata yatha, wofufuza yemwe adapeza vutoli
anamalizakuti chigamba chomwe chaperekedwa kwa ogwiritsa ntchito sichikonza vuto. Wofufuzayo adawonetsa kuti vutoli silichitika chifukwa chogawa ma adilesi a alendo (GPA), komanso ma adilesi omwe amakhala nawo (HPA). Tsamba lokumbukira likadutsa, makina ochezera alendo amatha kulembanso zomwe zili m'magawo a kukumbukira kwa kernel.
