I-XCP-ng, okuhlukile kwamahhala kwe-Citrix XenServer, ibe yingxenye yephrojekthi ye-Xen

Abathuthukisi I-XCP-ng, ukuthuthukisa indawo yamahhala nemahhala yesikhulumi sokuphathwa kwengqalasizinda yamafu i-XenServer (Citrix Hypervisor), kumenyezelwe mayelana nokujoyina iphrojekthi Xen, ukuthuthukiswa kwayo iyaqhubeka njengengxenye ye-Linux Foundation. Ukuhamba ngaphansi kwephiko le-Xen Project kuzovumela i-XCP-ng ukuthi ibhekwe njengokusabalalisa okujwayelekile kokukhipha ingqalasizinda yomshini ebonakalayo esekelwe ku-Xen hypervisor ne-XAPI.

Ukuhlanganisa neProjekthi ye-Xen kuzovumela i-XCP-ng, njengokusatshalaliswa kwabathengi, ukuthi ibe ibhuloho phakathi kwabasebenzisi nabathuthukisi, futhi kuqinisekise kubasebenzisi be-XCP-ng ukuthi iphrojekthi izoqhubeka nokulandela izimiso zayo zangempela esikhathini esizayo (hhayi umkhiqizo olinganiselwe wokuthengisa, njengoba kwenzeka nge-XenServer). Ukuhlanganiswa ngeke kuthinte kakhulu izinqubo zokuthuthukisa ezisetshenziswe ku-XCP-ng.

Ngasikhathi sinye ehlongozwayo ukuze kuhlolwe ukukhishwa kwe-beta kwe-XCP-ng 8.1, edala kabusha ukusebenza ICitrix Hypervisor 8.1 (phambilini ebibizwa nge-XenServer). Isekela ukuthuthukiswa kwe-XenServer kuya ku-XCP-ng, inikeza ukusebenzisana okugcwele ne-Xen Orchestra, futhi ikuvumela ukuba uhambise imishini ebonakalayo isuka ku-XenServer iye ku-XCP-ng futhi uyibuyisele emuva. Okokulayisha zilungisiwe 530 MB isithombe sokufaka.

Izithombe zokufakwa zokukhishwa okusha zakhiwe kusisekelo sephakheji le-CentOS 7.5 kusetshenziswa i-Linux 4.19 kernel kanye ne-hypervisor. I-Xen 4.13. Ushintsho oluphawuleka kakhulu ku-XCP-ng 8.1 kwaba ukuqiniswa kosekelo lokuqalisa izinhlelo zezivakashi kumodi ye-UEFI (Usekelo Lwe-Secure Boot aluzange ludluliselwe, njengoba luhlanganiswe nekhodi yobunikazi). Ukwengeza, ukusebenza kokungenisa nokuthumela ngaphandle kwemishini ebonakalayo kwenziwe ngcono.
ngefomethi ye-XVA, ukusebenza kwesitoreji sekuthuthukisiwe, abashayeli be-I/O abasha be-Windows bangeziwe, ukusekelwa kwama-chips e-AMD EPYC 7xx2(P) kwengeziwe, i-chrony isetshenzisiwe esikhundleni se-ntpd, ukusekelwa kwezinhlelo zezivakashi kwimodi ye-PV kuye kwafakwa. kuthiwa isiphelelwe yisikhathi, i-FS manje isisetshenziswa ngokuzenzakalelayo kusitoreji esisha sasendaweni i-Ext4, imojula yokuhlola ye-ZFS, ibuyekezelwe kunguqulo 0.8.2.

Masikhumbule ukuthi i-Citrix Hypervisor (XenServer) ne-XCP-NG ikuvumela ukuthi usebenzise ngokushesha uhlelo lwe-virtualization lwamaseva nezindawo zokusebenza, unikeze amathuluzi okuphatha okuphakathi kwenani elingenamkhawulo lamaseva nemishini ebonakalayo. Phakathi kwezici zesistimu: ikhono lokuhlanganisa amaseva amaningana echibini (iqoqo), amathuluzi Okutholakala Okuphezulu, ukusekelwa kwezifinyezo, ukwabelana ngezinsiza ezabiwe kusetshenziswa ubuchwepheshe be-XenMotion. Ukufuduka bukhoma kwemishini ebonakalayo phakathi kwabasingathi beqoqo naphakathi kwamaqoqo ahlukene/abasingathi abangabodwana (ngaphandle kwesitoreji esabelwe) kuyasekelwa, kanye nokufuduka okubukhoma kwamadiski e-VM phakathi kwesitoreji. Ipulatifomu ingasebenza nenani elikhulu lezinhlelo zokugcina idatha futhi ibonakala ngesikhombimsebenzisi esilula nesinembile sokufakwa nokuphatha.
