Ka dib sideed bilood oo horumarin ah, hypervisor-ka bilaashka ah ee Xen 4.16 ayaa la sii daayay. Shirkadaha sida Amazon, Arm, Bitdefender, Citrix iyo EPAM Systems ayaa ka qayb qaatay horumarinta sii deynta cusub. Siideynta cusboonaysiinta laanta Xen 4.16 waxay socon doontaa ilaa Juun 2, 2023, iyo daabacaadda hagaajinta nuglaanta ilaa Diseembar 2, 2024.
Isbeddellada muhiimka ah ee Xen 4.16:
- Maamulaha TPM, kaas oo hubinaya hawlgalka chips-ka-farsamada ah ee lagu kaydinayo furayaasha cryptographic (vTPM), oo lagu hirgeliyay habka caadiga ah ee TPM jireed (Trusted Platform Module), ayaa la saxay si uu markaa ka dib u fuliyo taageerada qeexitaanka TPM 2.0.
- Ku-tiirsanaanta korodhay ee lakabka PV Shim ee loo isticmaalo in lagu socodsiiyo martida paravirtualized (PV) aan la beddelin gudaha PVH iyo deegaanka HVM. Horey u socoshada, isticmaalka 32-bit martida paravirtualized kaliya waxay suurtogal noqon doontaa habka PV Shim, kaas oo yareyn doona tirada meelaha ku yaal hypervisor-ka kuwaas oo laga yaabo inay ku jiraan nuglaanta.
- Waxaa lagu daray awoodda lagu bootin karo aaladaha Intel iyada oo aan la hayn saacad-barnaamij la samayn karo (PIT, Timer Interval Timer).
- Nadiifinta qaybaha duugoobay, waxay joojisay dhisidda koodhka caadiga ah "qemu-xen-dhaqameed" iyo PV-Grub (baahida loo qabo fargeetoyadan gaarka ah ee Xen ayaa la waayay ka dib markii isbeddelada taageerada Xen loo wareejiyay qaab dhismeedka ugu weyn ee QEMU iyo Grub).
- Martida leh qaab dhismeedka ARM, taageerada bilowga ah ee xisaabiyeyaasha wax qabadka la taaban karo ayaa la hirgeliyay.
- Taageerada la wanaajiyay ee qaabka dom0less, taas oo kuu ogolaanaysa inaad iska ilaaliso inaad geyso deegaanka dom0 markaad bilaabayso mishiinada farsamada ee marxaladda hore ee boot server. Isbeddellada ayaa suurtageliyay in la hirgeliyo taageerada nidaamyada 64-bit ARM ee leh EFI firmware.
- Taageero la wanaajiyey oo loogu talagalay nidaamyada 64-bit ARM ee kala duwan oo ku salaysan qaab dhismeedka weyn. LITTLE, kaas oo isku daraya koofiyadaha awoodda leh laakiin awood-gaajaysan iyo waxqabad hoose laakiin awood badan oo waxtar leh oo hal jajab ah.
Isla mar ahaantaana, Intel ayaa daabacday sii deynta Cloud Hypervisor 20.0 hypervisor, oo lagu dhisay qaybaha mashruuca wadajirka ah ee Rust-VMM, kaas oo, marka lagu daro Intel, Alibaba, Amazon, Google iyo Koofiyada Cas sidoo kale ka qaybqaataan. Rust-VMM waxay ku qoran tahay luqadda Rust waxayna kuu ogolaaneysaa inaad abuurto hypervisors hawl gaar ah. Cloud Hypervisor waa mid ka mid ah hypervisor-ka kaas oo bixiya kormeeraha mashiinka farsamada ee heer sare ah (VMM) oo ku shaqeeya dusha sare ee KVM oo loo habeeyay hawlaha daruuriga ah. Koodhka mashruuca waxa lagu heli karaa shatiga Apache 2.0.
Cloud Hypervisor wuxuu diiradda saarayaa socodsiinta qaybinta casriga ah ee Linux iyadoo la adeegsanayo aaladaha paravirtualized-ku-saleysan. Ujeedooyinka muhiimka ah ee lagu xusay waxaa ka mid ah: jawaab celin sare, isticmaalka xusuusta oo yar, waxqabadka sare, qaabeynta la fududeeyay iyo yaraynta weerarada suurtagalka ah. Taageerada ku dayashada waxaa lagu hayaa ugu yaraan waxaana diiradda la saarayaa ka dhigista. Hadda nidaamyada x86_64 kaliya ayaa la taageeray, laakiin taageerada AArch64 waa la qorsheeyay. Nidaamyada martida, kaliya 64-bit dhismooyinka Linux ayaa hadda la taageerayaa. CPU, xusuusta, PCI iyo NVDIMM waxaa lagu habeeyey marxaladda kulanka. Waa suurtagal in loo guuro mashiinnada farsamada ee u dhexeeya server-yada.
Nooca cusub:
- x86_64 iyo aarch64 architectures, ilaa 16 qaybood PCI hadda waa la ogolyahay, taas oo kordhisa tirada guud ee qalabka PCI ee la ogolyahay min 31 ilaa 496.
- Taageerada ku xidhidhiyaha CPU-yada casriga ah ee CPU-yada jireed (Pinning CPU) waa la hirgaliyay. Mid kasta oo vCPU ah, hadda waxaa suurtagal ah in la qeexo xaddidan xaddidan oo ah martigeliyaha CPUs kaas oo fulinta la oggol yahay, kaas oo faa'iido u yeelan kara marka si toos ah loo dejiyo (1: 1) martigeliyaha iyo ilaha martida ama marka lagu shaqeeyo mashiinka farsamada ee NUMA gaar ah.
- Taageerada la wanaajiyay ee I/O habaynta. Gobol kasta oo VFIO ah hadda waxaa lagu dhejin karaa xusuusta, taas oo yaraynaysa tirada mishiinnada farsamada ee ka baxa waxayna wanaajisaa waxqabadka qalabka u gudbinta mashiinka farsamada.
- Xeerka miridhku, waxaa la sameeyay shaqada lagu bedelayo qaybaha aan badbaadada lahayn iyadoo lagu bedelay qaab nabdoon. Qaybaha haray ee aan badbaadada lahayn, faallooyin tafatiran ayaa lagu daray oo sharaxaya sababta koodka badbaadada ah ee hadhay loogu tixgelin karo badbaado.
