Kutulutsidwa kwa XCP-NG 8.1, mtundu waulere wa Citrix Hypervisor

Lofalitsidwa kutulutsidwa kwa polojekiti Zithunzi za XCP-NG 8.1, yomwe imapanga malo omasuka komanso omasuka a nsanja ya Citrix Hypervisor (yomwe poyamba inkatchedwa XenServer) kuti atumize ndi kuyang'anira ntchito ya zomangamanga zamtambo. XCP-NG imapangidwanso magwiridwe, yomwe Citrix yachotsa pamtundu waulere wa Citrix Hypervisor/Xen Server kuyambira mtundu 7.3. Kukweza Citrix Hypervisor kupita ku XCP-ng kumathandizidwa, kuyanjana kwathunthu ndi Xen Orchestra kumaperekedwa, komanso kuthekera kosuntha makina enieni kuchokera ku Citrix Hypervisor kupita ku XCP-ng ndi mosemphanitsa. Za kutsitsa okonzeka 600 MB chithunzi chokhazikitsa.

XCP-NG imakulolani kuti mutumize mwachangu makina opangira ma seva ndi malo ogwirira ntchito, ndikupereka zida zowongolera pakati pa ma seva ambiri ndi makina enieni. Zina mwazinthu za dongosololi: kuthekera kophatikiza ma seva angapo padziwe (tsango), kupezeka kwakukulu (Kupezeka Kwapamwamba), kuthandizira pazithunzithunzi, kugawana zinthu zomwe zimagwiritsidwa ntchito pogwiritsa ntchito ukadaulo wa XenMotion. Imathandizira kusamuka kwamoyo kwamakina apakati pakati pa makamu amagulu ndi pakati pa magulu osiyanasiyana / makamu amunthu payekha (popanda kusungirako nawo), komanso kusamuka kwamoyo kwa ma disks a VM pakati pa zosungira. Pulatifomu imatha kugwira ntchito ndi machitidwe ambiri osungirako ndipo imasiyanitsidwa ndi kukhalapo kwa mawonekedwe osavuta komanso owoneka bwino pakuyika ndi kuwongolera.

Kutulutsidwa kwatsopano sikumangopanganso magwiridwe antchito Citrix Hypervisor 8.1, komanso imapereka zosintha zina:

• Zithunzi zoyika za kumasulidwa kwatsopano zimamangidwa pa phukusi la CentOS 7.5 pogwiritsa ntchito hypervisor Chithunzi cha 4.13. Anawonjezera kuthekera kogwiritsa ntchito kernel ina ya Linux kutengera nthambi ya 4.19;
• Thandizo lokhazikika la machitidwe oyendetsa alendo mumayendedwe a UEFI (Thandizo la Boot Yotetezedwa silimasamutsidwa kuchokera ku Citrix Hypervisor, koma limapangidwa kuchokera pachiyambi kuti tipewe mphambano ndi code eni eni);
• Thandizo lowonjezera la zowonjezera za XAPI (XenServer/XCP-ng API) zomwe zimafunikira kuti zisungire makina enieni pojambula kagawo ka zomwe zili mu RAM yawo. Ogwiritsa ntchito adatha kubwezeretsa VM pamodzi ndi zochitika za kuphedwa komanso momwe RAM ikukhalira panthawi yosungira, mofanana ndi kubwezeretsa dongosolo la dongosolo pambuyo podzuka kuchokera ku hibernation (VM imayimitsidwa isanasungidwe);
• Kusintha kwapangidwa kwa oyika, omwe tsopano amapereka njira ziwiri zoyika: BIOS ndi UEFI. Zakale zitha kugwiritsidwa ntchito ngati kubwereranso pamakina omwe akukumana ndi zovuta za UEFI (monga zomwe zimachokera ku AMD Ryzen CPUs). Yachiwiri imagwiritsa ntchito Linux kernel (4.19) mwachisawawa;
• Kuchita bwino pakulowetsa ndi kutumiza makina enieni mumtundu wa XVA. Kuchita bwino kosungirako;
• Anawonjezera madalaivala atsopano a I/O a Windows;
• Thandizo lowonjezera la tchipisi ta AMD EPYC 7xx2(P);
• chrony imakhudzidwa m'malo mwa ntpd;
• Thandizo lotsitsidwa la machitidwe a alendo mu PV mode;
• Zosungira zatsopano zam'deralo tsopano zimagwiritsa ntchito Ext4 FS mwachisawawa;
• Thandizo lowonjezera loyesera pomanga zosungirako zakumalo kutengera fayilo ya XFS (imafuna kuyika phukusi la sm-additional-drivers);
• Gawo loyesera la ZFS lasinthidwa kukhala 0.8.2.
