Iphrojekthi yeXen ingenye yamaphrojekthi womthombo ovulekile othakazelisa kakhulu womhlaba we-virtualization. I-Xen iyi-hypervisor ekuvumela ukuthi usebenzise izinhlobo ezahlukahlukene zokwenza i-Linux (i-virtualization ephelele, i-paravirtualization). Manje okusha Inguqulo ye-4.12 enezindaba ezithokozisayo zabo bonke abasebenzisi nabaphathi abasekele ukubona kwabo kuXen. Enye yalezi zinto ezintsha ukwehliswa kwekhodi ukuze kuhlalwe kancane futhi kuthuthukiswe ngokwengeziwe.
Enye indlela entsha enhle ezungeze i- ukuphepha, okuqiniswe kakhulu kule nguqulo entsha. Kukhona nezinguquko ezithile zekhodi kubuchwepheshe be-x86, izibuyekezo ezenza ukuthi zifaneleke kakhulu kuzinhlelo zokusebenza ezishumekiwe kanye nemboni yezimoto. Ezinye zalezo zinguquko ezithinta ezokuphepha zithonya ikakhulukazi ukuhlanganiswa kwayo ne-QEMU, kanye ne-Argo, i-Virtual Machine Introspection (VMI) subsystem, njll.
Mayelana nezinguquko eziphathelene x86 ukwakha, iXen 4.12 entsha ivuselele ukwesekwa kwale ISA, umphumela womzamo weminyaka embalwa yokusebenza osekukhokhele manje. I-GRUB2 bootloader nayo ithinteka kahle ngenxa yezithuthukisi, njengoba ukwesekwa kungezwa ukuze abasebenzisi bakwazi ukuqala kusuka kunoma iyiphi isivakashi se-PVH kernel ngemenyu ye-GRUB.
Ngaphambilini ngike ngacaphuna okuthile ngokushumeka noma ikhefu futhi lezimoto. Ngalo mqondo, kwenziwe umsebenzi onzima ukwenza kube lula futhi kutholakale ukuthi iXen isetshenziswe ezinhlelweni ezixubekile ezibucayi. Futhi ukuphetha, asikwazi ukuphuthelwa eminye imisebenzi engeziwe kule nguqulo entsha, njengokuthuthuka kwekhodi yemephu ye-IOMMU ethinta kahle ukusebenza kwezinhlelo ezisuselwa ku-AMD EPYC.
