• Phakathi kwezinye izinto, XEN Umncedisi Platform-wadala iinkqubo ezahlukeneyo yokusebenza yeendwendwe kwinginginya computer.

Yintoni na?

Ngokwawo, i XEN - yinto hypervisor cross-eqongeni. Lo mgangatho ukhona luphuhliso eyodwa, eyeye kwiYunivesithi yaseCambridge kwaye ngoku yasasazwa kuphela yi GPL-mvume. Ekuqaleni ixhaswa kwamasebe amabini iphambili imveliso - koguqulelo kunye uguqulelo ikhowudi yemvelaphi, kodwa ngo-2009 kwathiwa ukuba zonke iinketho ze Umncedisi XEN iya kuba ngokupheleleyo ezamahala, ngoko ke iya kuba sisibonelelo free.

Uluvo olusisiseko hypervisor hlobo domain ukuba sele pre-laqalisa inguqulelo kumatshini onesiqhamo. Kwimeko ukuba uqala ukulayisha lonke iziphelo domain yaye kwasekwa enye emva ukulayisha. Nkqu inkqubo yokufuduka imixholo Umncedisi XEN iya zikhutshelwa phakathi kwabo. Ngenxa yoku, apha ekuhambeni ikhona, phantse zonke kumatshini onesiqhamo ekugqibeleni efolisiweyo kwi izibonelelo ezahlukeneyo, kodwa XEN isebenza ngqo kuphela ingqiqo idomeyini, nayo yonke enye into eza kuphela emva kufikwa ekunikeni ulawulo isicelo, ukubonelela ukulawula hypervisor.

Kutheni le nkqubo kangaka?

Namhlanje sinako ngokukhuselekileyo bathi XEN Umncedisi Citrix yenye yezona ndlela zinamandla ekwaziyo lweeHedfowuni zekhompyutha. Kufuneka kuqatshelwe ukuba okusingqongileyo fastest kwaye ikhuseleki- kuzo zonke iintlobo, kodwa yimveliso free ngokupheleleyo. Kodwa, Kakade, oko akunakuthethwa ukuba esi sigqibo liyaqonda jikelele ngokupheleleyo, yaye ngoko ke, kwezinye iimeko, abasebenzisi nako asebenzise ezinye iintlobo ze-software.

Indlela ukufaka kwaye ulungiselele?

Umncedisi XEN Citrix yenzelwe ukunika ukusebenza ngobuchule standard Windows kunye Linux yokusebenza neenkqubo. Kubalulekile ukuphawula ukuba ungakwazi ukusebenzisa ezinye iindlela amaqonga, kodwa umenzi kwenza akukho siqinisekiso sokuba baya kuphawula ukusebenza yesiqhelo.

Emva koko uya kubona screen okusenza ukuba ufake Umncedisi XEN 6.2 (okanye nayiphi na enye inguqulo ukuba uyilayishe). Emva edlula amanyathelo ufakelo ezilula iza ukuvala i window, ebonisa iqonga abathwele ufakelo echanekileyo.

Emva Kumncedisi lokugqibela XEN yokuqalelisa Kumncedisi Ubuntu, okanye ezinye iindidi lwamaqonga umsebenzisi sokuyivula ngokuzenzekela window engundoqo kwinkqubo ukubaleka. Kubonakala ngathi main menu zilayishwe XEN-nkqubo yinxalenye, kwaye ngexesha elinye yahlulwe ntsika zimbini, apho ngasekhohlo uyakwazi ukukhetha i parameters ezisisiseko ngokusebenzisa izitshixo zotolo lwebhodi, ngoxa ekunene uya kubona zonke ezi iinketho, ungasebenzisa ukuba ukuba ukutshintsha iimpahla ezithile kwindlela yokusebenza. Ukuya utshintsho olunjalo, kufuneka ukhethe into efunekayo kwaye ucofe ku Faka.

Ngoxa kwi window Management Umncedisi Ubuntu XEN, ungasebenzisa ubeko emfutshane Alt + F3 ukuba batshintshele umgangatho i Linux console, nto leyo kwakhona zingqina ukuba, ngokwayo, le platform umgangatho i Linux, baxhotyiswa kunye nezixhobo zabo, kwaye ziqondwe kakuhle kunye aziwayo abaninzi isethi imfundo. Kungenxa yesi sizathu ukuba abo bantu bangabanini Linux kwinkqubo yokusebenza, akukho nto enzima kwelo ngokukhawuleza kakhulu uziqhelanise iimpawu ezingundoqo umsebenzi kweli qonga.

Qwalasela inkqubo

Xa uqala umncedisi, usebenzisa idilesi ehambelana aya kuba nako ukujonga amakhonkco amabini ephambili browser. Ngokuba umntu, ungalayisha ezantsi XenCenter, esebenzisa apho ulawulo ngokupheleleyo kweqonga, lo gama enye i exe-fayile. Kunjalo, emva kokufakwa, uya kubonakala kulawulo console, emva kokuba uyifake idilesi yakho host, yaye ingcambu-password, yaye uya kunikwa imvume yokungena kwisistim.

Ukufumana ulwazi olusisiseko

Kwimo standard, umkhosi yokubaleka, uyakwazi ukujonga zombini ulwazi lwezibalo zobugcisa, kwaye perebiraniya tabs ngaphezulu kuya kuba lula ukufumana imvume yokungena kwi ezininzi ezinye iimvavanyo ezongezelelweyo kunye iparameters. Umzekelo, kwi tab Performance, uyakwazi ukujonga ulwazi olusisiseko malunga ntli host umatshini XEN Server, kokutyalwa esele yenziwe njani kungoku nje, ngokunjalo ukusebenzisa izibonelelo ezikhoyo ngayo.

Faka i guest

Ukuba ufuna ukubeka inkqubo guest umkhosi, kuya kufuneka uye kwindawo of New VM okanye nje i VM, kwaye emva kokuba kuvulwe le nto menu ukukhetha indlela yokusebenza kwinkqubo ofuna ukufaka njengondwendwe. Ngokukodwa, ukuba oyifunayo, nako kuthwalelwa phandle ufakelo Server XEN kwi Windows 7. Kubalulekile ukuphawula ukuba eli iqonga inika iintlobo ezahlukeneyo ngokufanelekileyo, kunye nenkqubo yokufaka twatse naleyo esetyenziswa VMware wedesktop. Oko kukuthi, i-nkqubo yahlulwe kwizigaba ezininzi:

• uhlobo zokukhangela;
• icwangcisa inombolo oyifunayo iziqhubekisi kunye memory;
• inkululeko lesithuba hard drive yakho okanye eliphakathi yokugcina elizinikeleyo ukuba ufakelo kwinkqubo yakhe entsha.

Ukuba ndanabo bam amava ubomi VMware wedesktop, unokuqiniseka ukuba lula ukungena imisebenzi ephambili kwaye lula uya kumisa wayenza Umncedisi XEN ufakelo okokuqala kwi Windows 7 okanye ezinye iintlobo lweenkqubo zokusebenza.

Ntoni okulandelayo?

Emva kokuba udale kwaye uqhuba imoto entsha, le nkqubo iba kakhulu umgangatho lofakelo indlela yokusebenza ukhetha. Kwaye akukho izinto ezintsha ngokupheleleyo. Kufuneka kuphela ukulinda de kube sekupheleni ukufaka njani inkqubo entsha, emva koko uya kukwazi ukuthatha kulixhamla eli console olona Server XEN. Amalungu VDI okanye ukuqalisa naziphi ezinye iindlela - konke oku ngoku ngaphakathi izakhono zenu, kwaye ungaserbenzisa i inkqubo njengoko ubona kufanelekile.

Ingxenye hardware

Musa ukulibala ukuba ukusebenza kwenkqubo luxhomekeke ngqo kwi wasebenzisa iintsimbi kuwe. Kungenxa yesi sizathu ukuba ephambili kuqala phambi kokuba wenze naluphi na ilifu kukubonelela abancedisi eziya kuba inkqubo lweeHedfowuni.

Ukuze kuqinisekiswe nokuya ngokwaneleyo ekhawulezileyo phakathi ezahlukeneyo IBM njengenxalenye bema usebenzisa iswitshi ezizodwa ukuba isondlo ukukhawulezisa ukufuduka amaxesha-10, kodwa practice kwezinga enjalo ngaphantsi kakhulu. Ukwenzela ukubonelela ukufikelela uthungelwano abancedisi kunye oomatshini virtual, utshintsho ezongezelelweyo zingadityaniswa kwi ukwakhiwa tu, ukuba ukuthumela izithuthi ukuze abathengi bangaphandle.

Ukongeza, nayo ebalulekileyo ukusetyenziswa kwemithombo amandla uninterruptible eza kuvumela inkqubo yokubuyisa ixesha ekuphulukenwe echanekileyo kumncedisi xa yokusilela umbane engundoqo.

Indlela lokubeka kumncedisi?

Ke nanku umbuzo, apho iya kugcinwa oomatshini yenyani. Ngaloo ndlela ke baya kubekwa kuphela abancedisi ngokwabo, kuba nefuthe elibi kakhulu phezu kwayo yonke le nkqubo iyonke, njengoko kunjalo naziphi na iziphene kufuneka ulahlekelwe ngokuzenzekelayo zonke koomatshini virtual usokhaya ku esi sixhobo.

Ukongeza asifanele, silibale ukuba le ndlela kwakhona nzima kakhulu kukulungelelanisa umthwalo umsebenzi jikelele, njengokuba ekuqaleni kuya kufuneka abanike virtual machine yokufudukela ukuhambisa drive yayo kwi enye iseva ethile, yaye oku bonke kudala imide kwaye usoloko udiniwe inkqubo.

Yenza izibonelelo womnatha virtual

Ukuze ukunika ngokwakho lula ukulawula izilungiselelo zenethiwekhi koomatshini virtual, ngokunjalo ukuqinisekisa ukuba sasi kwisa- subnet enye with "Umncedisi XEN", kuya kufuneka ukuba enze ukusekwa izibonelelo zenethiwekhi. Xa Citrix ekuqaleni ukuyipopola le ngxaki yaye yaqulunqa DVSC, nto leyo yayimelwe njenge kumatshini onesiqhamo, kodwa usebenzisa imemori kakhulu ngaphantsi kunye nezibonelelo.

Ukuba uye ngqo le web-ujongano lwe DVSC, uya kufumana kukho into eninzi ingcaciso eluncedo malunga yothungelwano lwezakhiwo, kuquka uluhlu koomatshini virtual zilawulwa ngoku ukudibanisa kumsebenzi womnatha ethile, zonke iintlobo imiyalezo yemposiso asakhasayo, ngokunjalo iigrafu of network umsebenzi ayikho kuphela ukuba umatshini ethile yesiqhamo, kodwa imigaqo inethiwekhi yonke.

DVSC kwakhona isetyenziswe ezikumgangatho firewall imithetho leyo zingacwangciswa nge AccessControl tab. Policy Network Ukhuseleko yahlulahlulwe imigangatho emine kunye nemithetho kuvumela ukuba uchaze uhlobo oluthile isenzo, lo protocol (leyo zingacwangciswa yi umthumeli umamkeli kumazibuko, kwakunye zibonisa imithetho elandelwayo eyaziwa), kwakunye abanye ngaye lo mgaqo iza kusetyenziswa.
