XCP-ng platvormi arendajad, kes tegutsevad Xen projekti raames, avaldasid plaani luua Rustis asendusi erinevatele Xen tarkvara komponentidele. Hetkel ei plaanita hyperviisorit Xen uuesti teha, vaid t\u00f6\u00f6 keskendub peamiselt \u00fcksikute t\u00f6\u00f6riistade komponentide \u00fcmbertegemisele. <\/p>\n

Praegu kasutab platvorm komponente keeltes C, Python, OCaml ja Go, millest m\u00f5ned on vananenud ja loomulikult p\u00f5hjustavad hooldamisega seotud probleeme. Toodud on v\u00e4lja, et Rusti kasutamine ei suurenda k\u00f5igi keelte arvu, kuna Go-s on teostatud vaid \u00fcks komponent, mida kavatsetakse k\u00f5igepealt asendada. <\/p>\n

Rust on valitud, kuna see \u00fchendab k\u00f5rge sooritusv\u00f5ime koostoodanguga koos m\u00e4lu turvalise haldamise v\u00f5imalustega, mis ei vaja pr\u00fcgikoristajat. Samuti sobib see nii madala kui ka k\u00f5rge taseme komponentide arendamiseks ning pakub t\u00e4iendavaid v\u00f5imalusi, et v\u00e4hendada v\u00f5imalikke vigu, nagu n\u00e4iteks muutuja laenamise kontroll (borrow checker). Rust on ka laiemalt levinud kui XAPI praegu kasutatav OCaml, mis lihtsustab uute arendajate kaasamist projektis. <\/p>\n

Esimeses etapis kavatsetakse arendada asendust mitmele komponendile, et t\u00f6\u00f6tada v\u00e4lja protsessid ja valmistada baasi teiste tarkvara osa asendamiseks. Eelk\u00f5ige kirjutatakse esmaj\u00e4rjekorras Rustis \u00fcmber Linux guest tools t\u00f6\u00f6riistad, mille jaoks praegu kasutatakse Go keelt, ning taustaprotsess, mis kogub m\u00f5\u00f5dikuid ja on kirjutatud OCaml-is. <\/p>\n

Linux guest tools (xe-guest-utilities) \u00fcmbertegemise vajadus tuleneb koodikvaliteedi probleemidest ja arengust, mis toimub v\u00e4ljaspool Xen Projecti Cloud Software Groupi kontrolli all, mis raskendab pakettide loomist ning m\u00f5jutab kogukonna osalemist arendust\u00f6\u00f6s. Uue t\u00f6\u00f6riistade variandi (xen-guest-agent) plaanitakse luua t\u00e4iesti nullist, muutes selle v\u00f5imalikult lihtsaks ning eraldades agendi loogika raamatukogudest. Taustaprotsessi, mis kogub m\u00f5\u00f5dikuid (rrdd), otsustati \u00fcmber teha, kuna see on kompaktne ja isoleeritud, mis lihtsustab katseid uue keele kasutamise osas arenduses. <\/p>\n

J\u00e4rgmisel aastal v\u00f5ib alata Rustis xenopsd-ng komponendi arendamine, mis optimeerib tarkvara arhiitehtuuri. Peamine idee on keskendada alamosade madala taseme API-d \u00fchte komponenti ja korraldada k\u00f5rge taseme API jagamine \u00fclej\u00e4\u00e4nud j\u00f5udluse komponentide vahel. <\/p>\n

Xeni praegune arhiitehtuuri struktuur:

\"Xen<\/center> <\/p>\n

Pakutud Xen arhiitehtuuri struktuur, mis p\u00f5hineb xenopsd-ng-l:
