Tsab xov xwm no yog kev txuas ntxiv ntawm tsab dhau los - "".
Nws yuav npog cov txheej txheem ntawm kev teeb tsa yooj yim thiab kev teeb tsa ntawm oVirt 4.3 cluster rau kev tuav cov tshuab virtual uas muaj ntau heev, xav txog tias txhua kauj ruam ua ntej rau kev npaj cov khoom siv twb tau ua tiav lawm.
Taw qhia
Lub hom phiaj tseem ceeb ntawm tsab xov xwm tsis yog los muab cov lus qhia ib kauj ruam zuj zus ntawm hom "Tom ntej no -> Yog -> Tag", tab sis kom qhia txog qee qhov tshwj xeeb ntawm nws qhov kev teeb tsa thiab kev teeb tsa. Cov txheej txheem rau kev xa koj pawg yuav tsis ib txwm phim qhov tau piav qhia nyob ntawd, vim yog qhov tshwj xeeb ntawm koj cov khoom siv thiab ib puag ncig, tab sis cov ntsiab cai dav dav yuav zoo ib yam.
Los ntawm ib qho kev xav ntawm tus kheej, Hais txog kev ua haujlwm, nws zoo ib yam li VMware vSphere version 5.x, tab sis tau kawg, nws muaj nws tus kheej configuration thiab operating features.
Rau cov neeg uas xav paub ntxiv, txhua qhov sib txawv ntawm RHEV (aka oVirt) thiab VMware vSphere tuaj yeem pom hauv online, piv txwv li , tab sis kuv tseem yuav sau qee qhov sib txawv lossis zoo sib xws ntawm lawv tus kheej, thaum tsab xov xwm txuas ntxiv mus.
Kuv kuj xav piv luv luv txog kev sib txuas lus rau cov tshuab virtual. oVirt siv lub hauv paus ntsiab lus zoo sib xws rau cov tshuab virtual (tom qab no VMs) li VMware vSphere:
- siv tus qauv Linux choj (hauv VMware - Tus qauv vSwitch), khiav ntawm cov chaw virtualization;
- siv Open vSwitch (OVS) (hauv VMware - vSwitch faib tawm) yog ib qho kev hloov pauv virtual faib tawm uas muaj ob lub ntsiab lus tseem ceeb: lub hauv paus OVN server thiab OVN controllers ntawm cov tswj hwm tswj hwm.
Yuav tsum nco ntsoov tias vim yog qhov yooj yim ntawm kev siv, tsab xov xwm no yuav piav qhia txog kev teeb tsa tes hauj lwm hauv oVirt rau VMs siv tus qauv Linux choj, uas yog tus qauv xaiv thaum siv KVM hypervisor.
Hauv qhov no, muaj ntau txoj cai yooj yim rau kev ua haujlwm nrog lub network hauv ib pawg uas zoo tshaj plaws tsis txhob ua txhaum:
- Txhua qhov chaw teeb tsa network ntawm cov tswv tsev yuav tsum zoo ib yam ua ntej ntxiv rau oVirt, tshwj tsis yog cov chaw nyob IP.
- Thaum ib tus tswv tsev nyob hauv qab oVirt txoj kev tswj hwm, nws raug pom zoo kom koj tsis txhob hloov pauv cov chaw teeb tsa network tshwj tsis yog tias koj ntseeg siab rau koj cov kev ua, vim tias tus neeg sawv cev oVirt yuav dov lawv rov qab mus rau lawv cov chaw teeb tsa yav dhau los tom qab rov pib dua tus tswv tsev lossis tus neeg sawv cev.
- Ntxiv lub network tshiab rau VM, nrog rau kev ua haujlwm nrog nws, tsuas yog yuav tsum tau ua los ntawm oVirt kev tswj hwm console.
Muaj ib yam ntxiv lus tseem ceeb — rau ib puag ncig uas muaj teeb meem loj heev (muaj kev cuam tshuam loj heev rau kev poob nyiaj txiag), nws tseem yuav pom zoo kom siv kev txhawb nqa them nyiaj thiab siv Thaum lub sijhawm ua haujlwm ntawm oVirt cluster, tej zaum yuav muaj qee yam teeb meem tshwm sim uas nws yog ib qho tseem ceeb kom nrhiav kev pab tsim nyog sai li sai tau es tsis txhob sim daws lawv koj tus kheej.
Thiab thaum kawg pom zoo Ua ntej yuav siv oVirt cluster, thov nyeem cov lus qhia no. , kom paub txog tsawg kawg yog cov ntsiab lus yooj yim thiab cov lus txhais, txwv tsis pub nws yuav nyuaj me ntsis nyeem cov ntawv seem.
Cov lus qhia hauv qab no yog qhov tseem ceeb rau kev nkag siab txog tsab xov xwm no thiab cov ntsiab cai ua haujlwm ntawm oVirt cluster:
Cov ntawv tsis loj heev, koj tuaj yeem kawm tau cov ntsiab cai yooj yim hauv ib teev lossis ob teev, thiab rau cov neeg nyiam cov ntsiab lus ntxaws ntxaws, nws raug pom zoo kom nyeem — RHEV thiab oVirt yeej zoo ib yam.
Yog li, yog tias tag nrho cov chaw teeb tsa yooj yim ntawm cov tswv tsev, cov hloov pauv, thiab cov kab ke khaws cia tiav lawm, peb mus ncaj qha mus rau kev xa tawm ntawm oVirt.
Ntu 2. Kev Txhim Kho thiab Kev Teeb tsa oVirt 4.3 Cluster
Rau qhov yooj yim ntawm kev siv, kuv yuav teev cov ntu tseem ceeb ntawm tsab xov xwm no, uas yuav tsum ua kom tiav raws li qhov kev txiav txim:
- Txhim kho lub oVirt management server
- Kev tsim ib lub chaw khaws ntaub ntawv tshiab
- Tsim ib pawg tshiab
- Kev teeb tsa cov hosts ntxiv rau hauv ib qho chaw uas muaj tus kheej tuav
- Tsim Ib Lub Chaw Khaws Khoom
- Tsim thiab teeb tsa cov tes hauj lwm rau cov tshuab virtual
- Tsim ib daim duab installation rau kev xa tawm lub tshuab virtual
- Tsim lub tshuab virtual
Txhim kho lub oVirt management server
oVirt Management Server - yog qhov tseem ceeb tshaj plaws hauv oVirt infrastructure, hauv daim ntawv ntawm lub tshuab virtual, tus tswv tsev, lossis lub cuab yeej virtual uas tswj hwm tag nrho oVirt infrastructure.
Nws cov analogues ze los ntawm lub ntiaj teb ntawm virtualization:
- VMware vSphere - vCenter Server
- Microsoft Hyper-V - System Center Virtual Machine Manager (VMM).
Txhawm rau nruab oVirt management server, peb muaj ob txoj kev xaiv:
Qhov 1
Xa ib lub server ua ib lub VM lossis tus tswv tsev tshwj xeeb.
Qhov kev xaiv no ua haujlwm zoo heev, tab sis tsuas yog tias VM zoo li no ua haujlwm ywj pheej ntawm pawg, piv txwv li nws tsis tau pib ntawm txhua tus tswv tsev cluster ua lub tshuab virtual ib txwm nyob hauv KVM tswj hwm.
Vim li cas ho tsis tuaj yeem siv VM zoo li no rau ntawm cov cluster hosts?
Thaum pib ntawm cov txheej txheem xa tawm oVirt kev tswj hwm server, peb ntsib teeb meem: peb yuav tsum tau nruab ib lub VM tswj hwm, tab sis lub cluster nws tus kheej tseem tsis tau muaj, yog li peb tuaj yeem ua dab tsi tam sim ntawd? Qhov yog ua yog nruab KVM rau ntawm lub cluster node yav tom ntej, tom qab ntawd tsim lub tshuab virtual rau nws, piv txwv li, khiav CentOS, thiab xa tawm lub cav oVirt rau nws. Qhov no yuav ua tau rau kev tswj hwm tag nrho ntawm VM zoo li no, tab sis qhov no yog lub tswv yim yuam kev, vim nws yuav ua rau muaj teeb meem nrog kev tswj hwm VM:
- nws yuav tsis yooj yim sua kom tsiv nws mus rau hauv oVirt console ntawm cov cluster hosts (nodes);
- thaum tsiv mus siv cov cuab yeej KVM virsh migrate, lub VM no yuav tsis muaj rau kev tswj hwm los ntawm oVirt console.
- cov cluster hosts tsis tuaj yeem tso tawm rau hauv Kho hom (hom kev saib xyuas) yog tias koj tsiv lub VM no los ntawm tus tswv tsev mus rau tus tswv tsev siv virsh migrate.
Yog li, ua txhua yam raws li txoj cai - siv tus tswv tsev sib cais rau oVirt kev tswj hwm server, lossis VM ywj pheej khiav ntawm nws, lossis, zoo dua, ua raws li qhov kev xaiv thib ob.
Qhov 2
Txhim kho oVirt Engine Appliance rau ntawm ib lub cluster host uas nws tswj hwm.
Qhov kev xaiv no yuav raug txiav txim siab ntxiv tias yog qhov tseeb thiab tsim nyog dua hauv peb qhov xwm txheej.
Cov kev cai rau VM zoo li no tau piav qhia hauv qab no. Kuv tsuas yog ntxiv tias nws raug pom zoo kom muaj tsawg kawg yog ob lub hosts hauv cov khoom siv uas VM tswj hwm tuaj yeem khiav kom ua rau nws ua haujlwm tau zoo. Kuv xav ntxiv tias, raws li kuv tau hais hauv cov lus hauv tsab xov xwm dhau los, kuv tseem tsis tau txais lub hlwb sib cais ntawm ib pawg oVirt ntawm ob lub hosts, nrog rau lub peev xwm los khiav hosted-engine VMs ntawm lawv.
Txhim kho oVirt Engine Appliance rau ntawm thawj lub cluster host
Txuas mus rau cov ntaub ntawv raug cai - , tshooj "»
Daim ntawv qhia txog cov kev cai ua ntej uas yuav tsum tau ua ua ntej xa tawm lub VM hosted-engine, thiab kuj piav qhia txog cov txheej txheem teeb tsa kom ntxaws, yog li tsis muaj qhov tshwj xeeb hauv kev rov ua dua nws verbatim, yog li peb yuav tsom mus rau qee cov ntsiab lus tseem ceeb.
- Ua ntej pib ua tej yam dab tsi, nco ntsoov qhib kev txhawb nqa virtualization hauv BIOS chaw ntawm tus tswv tsev.
- Nruab ib lub pob hosted-engine installer rau ntawm lub host:
yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
yum -y install epel-release
yum install screen ovirt-hosted-engine-setup- Peb tso tawm cov txheej txheem xa tawm oVirt Hosted Engine ntawm tus tswv tsev hauv ib qho screen (koj tuaj yeem tawm nws nrog Ctrl-A + D, kaw nws nrog Ctrl-D):
screen
hosted-engine --deployYog tias xav tau, koj tuaj yeem khiav qhov kev teeb tsa nrog cov ntaub ntawv teb uas tau npaj ua ntej:
hosted-engine --deploy --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-ohe.conf- Thaum xa tawm lub hosted-engine, peb teev tag nrho cov kev cai tsim nyog:
- имя кластера
- количество vCPU и vRAM (рекомендуется 4 vCPU и 16 Гб)
- пароли
- тип хранилища для hosted engine ВМ – в нашем случае FC
- номер LUN для установки hosted engine
- где будет находиться база данных для hosted engine – рекомендую для простоты выбрать Local (это БД PostgreSQL работающая внутри этой ВМ)
и др. параметры. - Txhawm rau nruab ib lub VM uas muaj ntau yam siv tau nrog lub cav uas tuav, peb tau tsim ib tus lej LUN tshwj xeeb 4 thiab qhov loj ntawm 150 GB ntawm lub kaw lus cia ua ntej, uas tom qab ntawd tau nthuav tawm rau cov tswv cuab pawg - saib hauv .
Peb kuj tau kuaj xyuas nws qhov pom kev ntawm cov tswv tsev ua ntej:

Yog tias txhua yam tau ua tiav lawm, tom qab kev teeb tsa tiav lawm, mus rau lub web browser los ntawm tus thawj coj lub computer, thiab nyem [Administration Portal].
Screenshot ntawm "Administration Portal"
Thaum koj nkag mus rau koj tus ID nkag mus thiab tus password (teem caij thaum lub sijhawm teeb tsa) hauv lub qhov rai uas pom hauv daim duab, koj yuav raug coj mus rau lub vaj huam sib luag qhib Virtualization Manager, qhov chaw koj tuaj yeem ua txhua yam haujlwm nrog koj lub hauv paus virtual:
- ntxiv ib lub chaw khaws ntaub ntawv
- ntxiv thiab teeb tsa ib pawg
- ntxiv thiab tswj cov tswv tsev
- ntxiv cov chaw cia khoom lossis Cov Chaw Khaws Khoom rau cov disks virtual machine
- ntxiv thiab teeb tsa cov tes hauj lwm rau cov tshuab virtual
- ntxiv thiab tswj cov tshuab virtual, cov duab teeb tsa, cov qauv VM
Tag nrho cov kev ua no yuav raug tham hauv qab no, qee qhov ua ntawv loj, qee qhov ua kom ntxaws ntxiv thiab nrog cov nuances.
Tiam sis ua ntej, kuv xav kom koj nyeem cov ntawv qhia no, uas yuav pab tau ntau tus neeg.
Txuas ntxiv
1) Hauv paus ntsiab lus, yog tias muaj qhov xav tau zoo li no, ces tsis muaj dab tsi tiv thaiv koj los ntawm kev txhim kho KVM hypervisor ntawm cov cluster nodes ua ntej siv cov pob khoom. libvirt и qemu-kwv (los yog qemu-kvm-ev) qhov version xav tau, txawm hais tias thaum xa tawm oVirt cluster node, nws tuaj yeem ua qhov no nws tus kheej.
Tab sis yog hais tias libvirt и qemu-kwv Yog tias koj tau teeb tsa ib qho version uas tsis yog qhov tseeb tshaj plaws, koj yuav tau txais qhov yuam kev hauv qab no thaum lub sijhawm hosted engine deployment:
error: unsupported configuration: unknown CPU feature: md-clearHais tias, yuav tsum muaj libvirt nrog kev tiv thaiv los ntawm , uas txhawb nqa txoj cai hauv qab no:
<feature policy='require' name='md-clear'/>Nruab libvirt v.4.5.0-10.el7_6.12, nrog kev txhawb nqa md-clear:

2) Hauv oVirt 4.3, qhov muaj thiab siv firewall firewalld yog ib qho yuav tsum tau ua.
Yog tias peb tau txais qhov yuam kev hauv qab no thaum lub sijhawm VM xa mus rau hosted-engine:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "firewalld is required to be enabled and active in order to correctly deploy hosted-engine. Please check, fix accordingly and re-deploy.n"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook
[https://bugzilla.redhat.com/show_bug.cgi?id=1608467Tom qab ntawd koj yuav tsum tua lwm lub firewall (yog tias siv ib qho), thiab nruab thiab khiav firewalld:
yum install firewalld
systemctl enable firewalld
systemctl start firewalld
firewall-cmd --state
firewall-cmd --get-default-zone
firewall-cmd --get-active-zones
firewall-cmd --get-zonesYav tom ntej, thaum txhim kho tus neeg sawv cev ovirt ntawm tus tswv tsev tshiab rau lub cluster, nws yuav teeb tsa cov chaw nres nkoj uas xav tau hauv firewalld tau txais.
3) Rov pib dua lub host nrog lub VM khiav ntawm nws nrog lub cav hosted.
Li qub, и ntawm cov ntaub ntawv tswj hwm.
Txhua qhov kev tswj hwm ntawm lub cav VM uas tau tuav tsuas yog ua tiav siv cov lus txib xwb hosted-engine ntawm tus tswv tsev qhov chaw uas nws ua haujlwm, txog virsh peb yuav tsum tsis txhob hnov qab, nrog rau qhov tseeb tias koj tuaj yeem txuas rau VM no ntawm SSH thiab ua cov lus txib "shutdown".

Qee zaum nws yog qhov tsim nyog los tshem tawm lub cav uas tau teeb tsa ua ntej - rau daim ntawv tswj hwm.
Peb tsuas yog ua cov lus txib ntawm tus tswv tsev:
/usr/sbin/ovirt-hosted-engine-cleanupTom ntej no, peb tshem tawm cov pob khoom tsis tsim nyog, thaub qab txhua qhov configs ua ntej, yog tias tsim nyog:
yum autoremove ovirt* qemu* virt* libvirt* libguestfs Kev tsim ib lub chaw khaws ntaub ntawv tshiab
Cov ntaub ntawv pab - oVirt Administration Guide.
Ua ntej, cia peb txhais nws yog dab tsi chaw khaws ntaub ntawv (Kuv hais los ntawm kev pab) yog ib qho chaw ua haujlwm uas txhais cov txheej txheem ntawm cov peev txheej siv hauv ib puag ncig tshwj xeeb.
Ib lub chaw khaws ntaub ntawv yog ib hom thawv uas muaj cov hauv qab no:
- cov peev txheej logical hauv daim ntawv ntawm cov pawg thiab cov tswv tsev
- cov peev txheej hauv network hauv daim ntawv ntawm cov logical networks thiab cov adapters lub cev ntawm cov tswv tsev,
- cov peev txheej cia khoom (rau VM disks, templates, images) hauv daim ntawv ntawm cov chaw cia khoom (Cia Domains).
Ib lub chaw khaws ntaub ntawv yuav muaj ntau pawg uas muaj ntau lub hosts nrog cov tshuab virtual khiav ntawm lawv, thiab nws kuj tseem yuav muaj ntau qhov chaw khaws ntaub ntawv cuam tshuam nrog nws.
Tej zaum yuav muaj ntau lub chaw khaws ntaub ntawv, txhua tus ua haujlwm ywj pheej. Ovirt tso cai rau kev tso cai raws li lub luag haujlwm, thiab tso cai rau kev tso cai tshwj xeeb, ob qho tib si ntawm qib chaw khaws ntaub ntawv thiab rau cov ntsiab lus ntawm tus kheej.
Lub chaw khaws ntaub ntawv, lossis cov chaw khaws ntaub ntawv yog tias muaj ntau qhov, raug tswj hwm los ntawm ib lub console lossis portal.
Yuav tsim ib lub chaw khaws ntaub ntawv, mus rau lub portal tswj hwm thiab tsim ib lub chaw khaws ntaub ntawv tshiab:
Compute >> Cov ntaub ntawv Centers >> Tshiab
Vim peb siv kev sib koom cia khoom ntawm lub kaw lus cia khoom, hom kev cia khoom (Hom Kev Cia Khoom) yuav tsum yog Sib Koom:
Daim duab ntawm tus kws tsim cov chaw khaws ntaub ntawv
Thaum txhim kho lub tshuab virtual nrog lub cav hosted, lub chaw khaws ntaub ntawv raug tsim los ntawm lub neej ntawd - Chaw khaws ntaub ntawv1, thiab tom qab ntawd, yog tias tsim nyog, koj tuaj yeem hloov hom cia khoom (Hom Cia Khoom) mus rau lwm qhov.
Kev tsim lub chaw khaws ntaub ntawv yog ib txoj haujlwm yooj yim, tsis muaj kev sib txawv, thiab txhua kauj ruam ntxiv tau piav qhia hauv cov ntaub ntawv. Kuv tsuas yog yuav sau tseg tias cov tswv tsev uas muaj chaw cia khoom hauv zos (disk) rau VMs yuav tsis tuaj yeem nkag mus (lossis ntxiv rau) lub chaw khaws ntaub ntawv nrog Hom Cia teeb tsa rau Sib Koom, thiab yuav tsum tsim lub chaw khaws ntaub ntawv sib cais rau lawv - uas yog, txhua tus tswv tsev nrog chaw cia khoom hauv zos xav tau nws lub chaw khaws ntaub ntawv.
Tsim ib pawg tshiab
Txuas rau cov ntaub ntawv: oVirt Administration Guide.
Tsis tas yuav piav qhia ntau yam, pawg Ib pawg yog ib pawg neeg sib koom ua ke ntawm cov tswv tsev uas sib koom ib qho chaw khaws cia (hauv daim ntawv ntawm cov disks sib koom ntawm lub kaw lus khaws cia, zoo li hauv peb qhov teeb meem). Nws kuj tseem xav tau rau cov tswv tsev hauv pawg kom zoo ib yam hauv cov khoom siv thiab muaj tib hom processor (Intel lossis AMD). Qhov zoo tshaj plaws, cov servers hauv pawg yuav tsum zoo ib yam kiag li.
Lub pawg yog ib feem ntawm lub chaw khaws ntaub ntawv (nrog rau ib hom kev khaws cia tshwj xeeb - Local los yog Sib), thiab txhua tus tswv tsev yuav tsum koom nrog qee pawg, nyob ntawm seb lawv puas muaj qhov chaw cia khoom sib koom lossis tsis.
Thaum txhim kho lub tshuab virtual nrog hosted-engine ntawm lub host, lub chaw khaws ntaub ntawv raug tsim los ntawm lub neej ntawd - Chaw khaws ntaub ntawv1, ua ke nrog pawg - Pawg1, thiab yav tom ntej koj tuaj yeem teeb tsa nws cov kev teeb tsa, qhib cov kev xaiv ntxiv, ntxiv cov tswv tsev rau nws, thiab lwm yam.
Ib yam li niaj zaus, yog xav paub ntxiv txog txhua qhov chaw teeb tsa ntawm pawg, nws raug pom zoo kom saib cov ntaub ntawv raug cai. Hais txog kev teeb tsa pawg, kuv tsuas yog ntxiv tias thaum tsim pawg, koj tsuas yog yuav tsum teeb tsa cov kev teeb tsa yooj yim ntawm lub tab. General.

Tsim Ib Lub Chaw Khaws Khoom
Cov ntaub ntawv txuas: oVirt Administration Guide, .
Chaw Khaws Khoom, lossis thaj chaw cia khoom, yog qhov chaw nruab nrab rau khaws cov disks virtual machine, cov duab teeb tsa, cov qauv, thiab cov duab thaij.
Cov chaw khaws ntaub ntawv tuaj yeem txuas nrog lub chaw khaws ntaub ntawv siv ntau yam protocols, cluster thiab network file systems.
oVirt muaj peb hom chaw cia khoom:
- Cov Ntaub Ntawv - rau kev khaws cia tag nrho cov ntaub ntawv cuam tshuam nrog cov tshuab virtual (disks, templates). Cov Ntaub Ntawv Domain tsis tuaj yeem sib koom ntawm cov chaw khaws ntaub ntawv sib txawv.
- ISO Domain (hom chaw khaws cia qub) - rau kev khaws cov duab teeb tsa OS. ISO Domain tuaj yeem sib koom ntawm cov chaw khaws ntaub ntawv sib txawv.
- Xa Tawm Lub Npe (hom chaw khaws cia qub txeeg qub teg) - rau kev khaws cia ib ntus ntawm cov duab tsiv mus rau ntawm cov chaw khaws ntaub ntawv.
Hauv peb qhov teeb meem tshwj xeeb, thaj chaw khaws cia nrog hom Data Domain siv Fibre Channel Protocol (FCP) los txuas rau LUNs ntawm lub kaw lus khaws cia.
Los ntawm oVirt qhov kev xav, thaum siv qhov chaw cia khoom (FC lossis iSCSI), txhua lub virtual disk, snapshot, lossis template yog lub logical disk.
Cov khoom siv thaiv tau sau ua ke (ntawm cov cluster hosts) siv Volume Group thiab tom qab ntawd faib siv LVM rau hauv cov ntim logical siv ua virtual disks rau VMs.
Tag nrho cov pab pawg no thiab ntau lub ntim LVM tuaj yeem pom ntawm tus tswv tsev cluster siv cov lus txib lwm и lvs uaNtawm chav kawm, txhua yam kev ua nrog cov disks zoo li no yuav tsum tau ua los ntawm oVirt console xwb, tshwj tsis yog hauv cov xwm txheej tshwj xeeb.
Cov disk virtual rau VMs tuaj yeem muaj ob hom: QCOW2 lossis RAW. Cov disks tuaj yeem yog "nyias nyias"los yog"tuab". Cov duab thaij ib txwm raug tsim ua "nyias nyias".
Txoj kev uas cov chaw khaws cia, lossis cov chaw khaws cia nkag mus los ntawm Fibre Channel (FC), raug tswj hwm yog qhov muaj txiaj ntsig zoo: txhua lub VM virtual disk muaj ib lub ntim sib cais, sau tau los ntawm ib tus tswv tsev xwb. Rau kev sib txuas FC, oVirt siv qee yam zoo ib yam li clustered LVM.
Cov tshuab virtual uas nyob rau tib qho chaw khaws khoom tuaj yeem tsiv mus rau ntawm cov tswv tsev uas koom nrog tib pawg.
Raws li peb tuaj yeem pom los ntawm cov lus piav qhia, ib pawg hauv oVirt, zoo li ib pawg hauv VMware vSphere lossis Hyper-V, yeej txhais tau tib yam: nws yog ib pawg neeg sib koom ua ke ntawm cov tswv tsev, zoo ib yam li cov khoom siv kho vajtse, thiab muaj qhov chaw cia khoom rau cov disks virtual.
Cia peb txav mus ncaj qha mus rau kev tsim thaj chaw khaws cov ntaub ntawv (VM disks), vim tias yog tsis muaj nws lub chaw khaws ntaub ntawv yuav tsis raug pib.
Cia kuv nco ntsoov koj tias txhua LUNs uas tau nthuav tawm rau cov cluster hosts ntawm lub system cia khoom yuav tsum pom ntawm lawv siv cov lus txib "ntau txoj kev -ll".
Raws li , peb mus rau lub portal, peb mus rau hauv cia >> puav -> Lub Npe Tshiab thiab ua raws li cov lus qhia hauv ntu "Ntxiv FCP Cia".
