Ko tenei tuhinga he haere tonu o te korero o mua - "".
Ka hipokina te tukanga o te whakaurunga taketake me te whirihoranga o te roopu oVirt 4.3 mo te manaaki i nga miihini mariko tino watea, me te whakaaro kua oti kee nga mahi tuatahi mo te whakarite i nga hanganga i mua.
Kupu whakataki
Ko te kaupapa matua o te tuhinga ko te whakarato i nga tohutohu taahiraa-i-taahiraa penei "Panuku -> Āe -> Mutu"me pehea te whakaatu i etahi ahuatanga i te wa e whakauru ana me te whirihora. Ko te tikanga mo te tuku i to huinga kare pea i te rite tonu ki tera e whakaahuatia ana i roto, na nga ahuatanga o te hanganga me te taiao, engari ka rite tonu nga tikanga whanui.
Mai i te tirohanga kaupapa, he rite tonu tana mahi ki te VMware vSphere putanga 5.x, engari ko te tikanga me ona ake whirihoranga me nga ahuatanga mahi.
Mo te hunga e hiahia ana, ko nga rereketanga katoa i waenga i te RHEV (aka oVirt) me te VMware vSphere ka kitea i runga i te Ipurangi, hei tauira. , engari ka kite tonu ahau i etahi wa i etahi o o raatau rereketanga me o raatau rite ki a raatau i te wa e haere ana te tuhinga.
Ka wehe, ka hiahia ahau ki te whakataurite i nga mahi me nga whatunga mo nga miihini mariko. Ka whakatinanahia e te oVirt tetahi tikanga mo te whakahaere whatunga mo nga miihini mariko (ka kiia i muri nei ko VM), penei i roto i te VMware vSphere:
- te whakamahi i te piriti Linux paerewa (i VMware - Paerewa vSwitch), e rere ana i runga i nga kaihautu mariko;
- whakamahi Open vSwitch (OVS) (i roto i te VMware - Kua tohatohahia te vSwitch) he whakawhiti mariko kua tohatohahia e rua nga waahanga matua: he tūmau OVN pokapū me nga kaiwhakahaere OVN i runga i nga ope whakahaere.
Me tohu na te ngawari o te whakatinanatanga, ka whakaahuahia e te tuhinga te whakatu i nga whatunga i roto i te oVirt mo te VM ma te whakamahi i te piriti Linux paerewa, koinei te whiringa paerewa i te wa e whakamahi ana i te KVM hypervisor.
Mo tenei kaupapa, he maha nga ture matua mo te mahi me te whatunga i roto i te roopu, he pai ake kia kaua e takahia:
- Ko nga tautuhinga whatunga katoa i runga i nga kaihautu i mua i te taapiri atu ki oVirt me rite, engari mo nga wahitau IP.
- I te wa i mauhia ai tetahi kaihautu i raro i te mana o oVirt, kaore i te tūtohutia kia whakarereketia tetahi mea i roto i nga tautuhinga whatunga me te kore e tino maia ki o mahi, na te mea ka huri noa te kaihoko oVirt ki nga mea o mua i muri i te whakaara ano i te kaihautu, te kaihoko ranei .
- Ko te taapiri i tetahi whatunga hou mo te VM, me te mahi tahi, me mahi noa mai i te papatohu whakahaere oVirt.
Ko tetahi atu tuhipoka nui - mo te taiao tino nui (tino tairongo ki te ngaronga moni), ka tūtohu tonu kia whakamahia te tautoko me te whakamahi. . I te wa e whakahaerea ana te roopu oVirt, ka ara ake etahi take he mea tika kia whiwhi awhina whaimana i te wa e taea ai, kaua e mahi maau ake.
Hei whakamutunga, tūtohutia I mua i te tuku i te roopu oVirt, kia mohio koe , kia mohio ai koe ki nga ariā me nga whakamaramatanga, ki te kore he uaua ki te panui i te toenga o te tuhinga.
Ko te mea nui ki te maarama ki te tuhinga me nga maataapono o te mahi o te roopu oVirt enei tuhinga aratohu:
Ko te rōrahi kei reira kaore i te tino nui, i roto i te haora, e rua ranei ka taea e koe te mohio ki nga kaupapa matua, engari mo te hunga e pai ana ki nga korero, ka tūtohu kia panui. — RHEV me te oVirt he mea rite tonu.
Na, ki te mea kua oti katoa nga tautuhinga taketake i runga i nga kaihautu, nga huringa me nga punaha rokiroki, ka haere tika ki te tuku oVirt.
Wāhanga 2. Te tāuta me te whirihora i te kāhui oVirt 4.3
Mo te ngawari o te whakatakotoranga, ka whakarārangihia e au nga waahanga matua o tenei tuhinga, me whakaoti takitahi:
- Te tāuta i te tūmau whakahaere oVirt
- Te hanga i tetahi pokapū raraunga hou
- Te hanga i te huinga hou
- Te whakauru i etahi atu kaihautu i roto i te taiao-whaiaro
- Te hanga i tetahi waahi rokiroki, Rohe Rokiroki ranei
- Te hanga me te whirihora whatunga mo nga miihini mariko
- Te hanga pikitia whakaurunga mo te tuku miihini mariko
- Waihangahia he miihini mariko
Te tāuta i te tūmau whakahaere oVirt
tūmau whakahaere oVirt - koinei te mea tino nui i roto i te hanganga oVirt, i te ahua o te miihini mariko, te kaihautu, te taputapu mariko ranei e whakahaere ana i nga hanganga oVirt katoa.
Ko ona ahuatanga tata mai i te ao mariko ko:
- VMware vSphere - Tūmau vCenter
- Microsoft Hyper-V - Kaiwhakahaere Miihini Mariko Pokapū Pūnaha (VMM).
Hei whakauru i te tūmau whakahaere oVirt, e rua nga whiringa:
Kōwhiringa 1
Te tuku i te tūmau i roto i te ahua o te VM motuhake, kaihautū ranei.
He pai te mahi o tenei whiringa, engari mena ka mahi motuhake taua VM mai i te tautau, i.e. kaore i te rere i runga i tetahi kaihautu roopu hei miihini mariko auau e whakahaere ana i te KVM.
He aha te take e kore ai e tukuna taua VM ki runga i nga kaihautu tautau?
I te timatanga o te mahi ki te tuku i te tūmau whakahaere oVirt, he raru to maatau - me whakauru he VM whakahaere, engari ko te mea kaore ano he kahui, na reira he aha ta tatou e haere mai i runga i te rere? Ka tika - whakauruhia te KVM ki runga i te node kahui a meake nei, katahi ka hangaia he miihini mariko ki runga, hei tauira, me te CentOS OS ka toha te miihini oVirt ki roto. Ka taea tenei mo nga take o te mana whakahaere mo taua VM, engari he whakaaro pohehe tenei, na te mea i tenei keehi, i nga wa kei te heke mai ka 100% nga raru o taua VM mana:
- e kore e taea te heke ki te papatohu oVirt i waenga i nga kaihautu (nodes) o te tautau;
- i te hekenga ma te whakamahi KVM ma virsh migrate, kaore tenei VM e waatea mo te whakahaere mai i te papatohu oVirt.
- Kaore e taea te whakaatu i nga kaihautu tautau Aratau Whakatikatika (aratau tiaki), mena ka heke koe i tenei VM mai i te kaihautu ki te kaihautu ma te whakamahi virsh migrate.
Na me mahi nga mea katoa kia rite ki nga ture - whakamahia he kaihautu motuhake mo te tūmau whakahaere oVirt, he VM motuhake ranei e rere ana i runga, he pai ake ranei, mahia kia rite ki te tuhi i te waahanga tuarua.
Kōwhiringa 2
Te whakauru oVirt Engine Appliance ki runga i te kaihautu roopu e whakahaeretia ana e ia.
Ko tenei waahanga ka whakaarohia he tika ake, he pai ake mo taatau.
Ko nga whakaritenga mo taua VM e whakaahuatia ana i raro nei; Ka tapiritia e ahau ko te tūtohu kia rua nga kaihautu i roto i nga hanganga e taea ai te whakahaere VM mana kia pai ai te he. I konei ka hiahia ahau ki te taapiri i tera, i te mea kua tuhia e au i roto i nga korero i roto i te tuhinga o mua, kaore i taea e au roroa wehe i runga i te huinga oVirt o nga kaihautu e rua, me te kaha ki te whakahaere i nga VM miihini-whakahau ki runga i a raatau.
Te whakauru oVirt Engine Appliance ki te ope tuatahi o te tautau
Hononga ki nga tuhinga whaimana - , pene "»
Ko te tuhinga e whakaatu ana i nga whakaritenga e tika ana kia tutuki i mua i te whakamahi i te VM miihini-whakahau, me te whakamaarama hoki i nga korero mo te whakaurunga ake, na reira he iti noa te tikanga ki te whakahoki ano i te kupu, no reira ka aro taatau ki etahi korero nui.
- I mua i te tiimata i nga mahi katoa, me mohio ki te whakahohe i te tautoko mariko i nga tautuhinga BIOS i runga i te kaihautu.
- Tāutahia te mōkihi mō te pūtāuta pūkaha-whakahau ki te kaihautū:
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- Ka timata matou i te tikanga mo te tuku oVirt Hosted Engine ki te mata o te kaihautu (ka taea e koe te puta ma Ctrl-A + D, kati ma Ctrl-D):
screen
hosted-engine --deployKi te hiahia koe, ka taea e koe te whakahaere i te whakaurunga me te konae whakautu kua oti te whakarite:
hosted-engine --deploy --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-ohe.conf- I te wa e tukuna ana te miihini-whakahau, ka tohua e matou nga tawhā e tika ana:
- 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. - Hei whakauru i tetahi VM tino waatea me te miihini whakahaere, i hangaia e matou he LUN motuhake i runga i te punaha rokiroki, te nama 4 me te 150 GB te rahi, katahi ka tukuna atu ki nga roopu roopu - tirohia. .
I mua i tirohia ano e matou tana tirohanga ki nga kaihautu:

Mena i tika nga mahi katoa, ka oti te whakaurunga, whakamahia he kaitirotiro paetukutuku hei haere ki mai i te rorohiko a te kaiwhakahaere, ka paato i te [Pouaka Whakahaere].
Whakaahuamata o te "Waehere Whakahaere"
Ma te whakauru i te takiuru me te kupuhipa (whakaturia i te wa o te whakaurunga) ki roto i te matapihi penei i te whakaahua, ka tae atu matou ki te Paewhiri Mana Whakahaere Whakahaere Mariko, ka taea e koe te mahi i nga mahi katoa me te hanganga mariko:
- tāpiri pokapū raraunga
- tāpiri me te whirihora i tētahi kāhui
- taapiri me te whakahaere i nga kaihautu
- tāpiri wāhi rokiroki, Rohe Rokiroki ranei mo nga kopae miihini mariko
- te taapiri me te whirihora i nga whatunga mo nga miihini mariko
- taapiri me te whakahaere i nga miihini mariko, nga whakaahua whakaurunga, nga tauira VM
Ko enei mahi katoa ka korerohia ano, ko etahi kei roto i nga ruma nui, ko etahi i roto i nga taipitopito me nga ahuatanga.
Engari i te tuatahi ka tūtohu ahau ki te panui i tenei taapiri, tera pea ka whai hua ki te tini.
Tāpiri
1) Ko te tikanga, mena he hiahia pera, kaore he mea hei aukati i a koe ki te whakauru i te KVM hypervisor i runga i nga kohinga tautau i mua i te whakamahi i nga kete. tahua и qemu-kvm (ranei qemu-kvm-ev) o te putanga e hiahiatia ana, ahakoa ka tukuna he node tautau oVirt, ka taea e ia ano te mahi.
Engari mena tahua и qemu-kvm Mena kaore i whakauruhia e koe te putanga hou, ka whiwhi pea koe i te hapa e whai ake nei i te wa e tukuna ana he miihini manaaki:
error: unsupported configuration: unknown CPU feature: md-clearKo era. me whai tahua me te tiaki mai , e tautoko ana i tenei kaupapa here:
<feature policy='require' name='md-clear'/>Tāutahia te libvirt v.4.5.0-10.el7_6.12, me te tautoko md-clear:

2) I roto i te oVirt 4.3, te noho me te whakamahi i te papangaahi firewalld he whakaritenga whakahau.
Mena i te wa e tukuna ana he VM mo te miihini-whakahau ka whiwhi tatou i te hapa e whai ake nei:
[ 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=1608467Na ka hiahia koe ki te whakaweto i tetahi atu papangaahi (mehemea ka whakamahia), ka whakauru me te whakahaere 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-zonesI muri mai, ka whakauruhia te kaihoko ovirt ki runga i tetahi kaihautu hou mo te tautau, ka whirihora e ia nga tauranga e hiahiatia ana i roto firewalld aunoa.
3) Te whakaara ano i tetahi kaihautu me te VM e rere ana me te miihini manaaki.
Ka rite ki te tikanga, и ki nga tuhinga whakahaere.
Ko nga whakahaere katoa o te miihini VM e whakahaerehia ana ka mahia ANAKE ma te whakamahi i te whakahau hautū-engine i runga i te ope e rere ana, mo wahine me wareware tatou, me te mea ka taea e koe te hono atu ki tenei VM ma te SSH ka whakahaere i te whakahau "tutakina".

I etahi wa ka tika te tango i tetahi miihini kua whakauruhia i mua - ki te tuhinga aratohu.
Whakahaere noa i te whakahau ki te kaihautu:
/usr/sbin/ovirt-hosted-engine-cleanupI muri mai, ka tangohia e matou nga kohinga koretake, me te tautoko i etahi whirihora i mua i tenei, ki te tika:
yum autoremove ovirt* qemu* virt* libvirt* libguestfs Te hanga i tetahi pokapū raraunga hou
Nga tuhinga tohutoro - Aratohu Whakahaere oVirt.
Tuatahi me tautuhi he aha tena pokapū raraunga (Ka whakahua ahau mai i te awhina) he hinonga arorau e tautuhi ana i te huinga rauemi e whakamahia ana i roto i tetahi taiao motuhake.
Ko te pokapū raraunga he momo ipu kei roto:
- rauemi arorau i roto i te ahua o te tautau me te ope
- nga rauemi whatunga huinga i te ahua o nga whatunga arorau me nga urutau tinana ki nga kaihautu,
- rauemi rokiroki (mo nga kopae VM, tauira, whakaahua) i roto i te ahua o nga waahi rokiroki (Nga Rohe Rokiroki).
Ka taea e te pokapū raraunga te whakauru i nga tautau maha kei roto i nga kaihautu maha me nga miihini mariko e rere ana i runga i a raatau, a he maha nga waahi rokiroki e hono ana ki a ia.
He maha nga pokapū raraunga; ka mahi takitahi tetahi ki tetahi. He wehewehenga mana a Ovirt i runga i te mahi, a ka taea e koe te whirihora i nga whakaaetanga takitahi, i te taumata pokapū raraunga me ona huānga arorau takitahi.
Ko te pokapū raraunga, he pokapū raraunga ranei mena he maha o raatau, ka whakahaerehia mai i te papatohu whakahaere kotahi, i te tomokanga ranei.
Hei waihanga i tetahi pokapū raraunga, haere ki te tomokanga whakahaere me te hanga i tetahi pokapū raraunga hou:
Whakauru >> Pokapū raraunga >> New
I te mea ka whakamahia e matou te rokiroki tiritahi ki te punaha rokiroki, me Tirihia te Momo Rokiroki:
Whakaahuamata o te Ruānuku Hangahanga Pokapū Raraunga
I te wa e whakauru ana i te miihini mariko me te miihini-whakataki, ka hangaia he pokapū raraunga ma te taunoa - Pokapū Raraunga1, a, ki te tika, ka taea e koe te huri i tana Momo Rokiroki ki tetahi atu.
Ko te hanga i tetahi pokapu raraunga he mahi ngawari, kaore he ahua uaua, a ko nga mahi taapiri katoa e whakaahuahia ana i roto i nga tuhinga. Ko te mea anake ka kite ahau ko nga kaihautu kotahi kei a ratou anake te rokiroki (kopae) mo nga VM e kore e uru ki roto i te pokapu raraunga me te Momo Rokiroki - Tiri (kaore e taea te taapiri atu ki reira), a mo ratou me hanga e koe. he pokapū raraunga motuhake - i.e. Ko ia kaihautu takitahi me te rokiroki rohe e hiahia ana ki tana ake pokapū raraunga motuhake.
Te hanga i te huinga hou
Hononga ki nga tuhinga - Aratohu Whakahaere oVirt.
Kaore he korero koretake, tautau – he whakarōpū arorau tenei o nga kaihautu he waahi rokiroki noa (i te ahua o nga kōpae tiritahi i runga i te punaha rokiroki, penei i a maatau). He mea pai ano kia rite nga kaihautu i roto i te roopu ki nga taputapu me te rite tonu te momo tukatuka (Intel, AMD ranei). Ko te mea pai rawa atu, ko nga kaitoro kei roto i te tautau he tino rite.
Ko te tautau he waahanga o te pokapū raraunga (me tetahi momo rokiroki - rohe ranei Tiria), a me uru nga kaihautu katoa ki etahi momo kapoi, i runga ano i te mea kua tohatoha ratou ki te rokiroki, kaore ranei.
I te wa e whakauru ana i te miihini mariko me te miihini-whakahau ki runga i te kaihautu, ka hangaia he pokapū raraunga ma te taunoa - Pokapū Raraunga1, me te tautau— Rōpū1, a kei te heke mai ka taea e koe te whirihora i ona tawhā, ka taea etahi atu whiringa, te taapiri i nga kaihautu ki a ia, me era atu.
Ka rite ki o mua, mo nga korero mo nga huinga huinga katoa, he pai ki te titiro ki nga tuhinga whaimana. O etahi o nga ahuatanga o te whakatu i tetahi tautau, ka taapiri noa e au i te wa e hanga ana, he nui ki te whirihora noa i nga tawhā taketake i runga i te ripa. General.
Ka kite ahau i nga tawhā tino nui:
- Momo tukatuka — ka tohua i runga i nga kaitukatuka e whakauruhia ana ki runga i nga roopu roopu, he aha te kaihanga mai i a raatau, a ko tehea tukatuka i runga i nga kaihautu te mea tawhito, na, i runga i tenei, ka whakamahia nga tohutohu tukatuka katoa e waatea ana i roto i te kohinga.
- Huri momo - i roto i ta maatau roopu ka whakamahi noa matou i te piriti Linux, na reira ka whiriwhiria e matou.
- Momo pātūahi – He maamaa nga mea katoa i konei, he paahi ahi tenei, me whakahoa me te whirihora ki nga kaihautu.
Whakaahuamata me nga tawhā tautau
Te whakauru i etahi atu kaihautu i roto i te taiao-whaiaro
mo nga tuhinga.
Ko nga kaihautu taapiri mo te taiao Whaiaro-whaiaro ka taapirihia kia rite ki te kaihautu i nga wa katoa, me te waahanga taapiri mo te tuku VM me te miihini manaaki - Whiriwhiria nga mahi whakangao miihini e whakahaerehia ana >> tohatoha. I te mea me whakaatu ano te kaihautu taapiri me te LUN mo te VM me te miihini manaaki, ko te tikanga ka taea e tenei kaihautu, ki te tika, te whakamahi ki te manaaki i tetahi VM me te miihini manaaki kei runga.
Mo nga kaupapa whakaraerae he, e tino taunaki ana kia rua nga kaihautu ka taea te whakanoho i tetahi miihini VM manaaki.
I runga i te kaihautu taapiri, whakakorehia nga iptables (mehemea ka taea), whakaahei te paahi ahi

Te hanga i tetahi waahi rokiroki, Rohe Rokiroki ranei
Hononga ki nga tuhinga - Aratohu Whakahaere oVirt, .
Rohe Rokiroki, he waahi rokiroki ranei, he waahi nui mo te penapena i nga kopae miihini mariko, nga whakaahua whakaurunga, nga tauira, me nga whakaahua.
Ko nga waahi rokiroki ka taea te hono atu ki te pokapū raraunga ma te whakamahi i nga momo kawa, te roopu me nga punaha konae whatunga.
E toru nga momo waahi rokiroki a oVirt:
- Rohe Raraunga – ki te penapena i nga raraunga katoa e pa ana ki nga miihini mariko (kopae, tauira). Ko te Rohe Raraunga e kore e taea te tiri ki waenga i nga pokapu raraunga rereke.
- Rohe ISO (te momo waahi putunga tawhito) – mo te penapena whakaahua whakaurunga OS. Ka taea te tiritahi i te Rohe ISO ki waenga i nga pokapu raraunga rereke.
- Rohe Kaweake (momo waahi putunga tawhito) – mo te rokiroki rangitahi o nga whakaahua i nekehia i waenga i nga pokapū raraunga.
I roto i ta maatau take, he waahi rokiroki me te momo Raraunga Raraunga e whakamahi ana i te Kawa Hoerarangi Fiber (FCP) hei hono atu ki nga LUN i runga i te punaha rokiroki.
Mai i te tirohanga o oVirt, i te wa e whakamahi ana i nga punaha rokiroki (FC, iSCSI ranei), ko ia kōpae mariko, whakaahua, tauira tauira ranei he kōpae arorau.
Ka whakahiatohia nga taputapu poraka ki te waeine kotahi (i runga i nga kaihautu tautau) ma te whakamahi i te Rōpū Rōrahi katahi ka wehewehea ma te whakamahi i te LVM ki nga pukapuka arorau, ka whakamahia hei kōpae mariko mo nga VM.
Ko enei roopu katoa me te maha o nga pukapuka LVM ka kitea i runga i te ope kaapu ma te whakamahi i nga whakahau etc и Lvs. Ko te tikanga, ko nga mahi katoa me enei kopae me mahi anake mai i te papatohu oVirt, engari i nga keehi motuhake.
Ko nga kōpae mariko mo nga VM e rua nga momo - QCOW2, RAW ranei. Ko nga kōpae pea "kikokore"ranei"mātotoru". Ka hangaia nga whakaahua hei "kikokore".
Ko te huarahi ki te whakahaere i nga rohe Rokiroki, nga waahi rokiroki ranei ka uru atu ma te FC, he tino arorau - mo ia kōpae mariko VM he rōrahi arorau motuhake ka taea te tuhi e te kaihautu kotahi anake. Mo nga hononga FC, ka whakamahia e oVirt tetahi mea penei i te LVM kua rapoi.
Ko nga miihini mariko kei runga i te waahi rokiroki kotahi ka taea te heke ki waenga i nga kaihautu no te roopu kotahi.
Ka kitea e tatou i te whakaahuatanga, he tautau i roto i te oVirt, penei i te tautau i roto i te VMware vSphere, Hyper-V ranei, he rite tonu te tikanga - he whakarōpū arorau o nga kaihautu, he rite tonu ki te hanganga taputapu, me te rokiroki noa mo te mariko. kopae miihini.
Me haere tika ki te hanga i tetahi waahi rokiroki mo nga raraunga (kopae VM), na te mea karekau te pokapū raraunga e arawhiti.
Me whakamahara ahau ki a koe ko nga LUN katoa e tukuna ana ki nga kaihautu tautau i runga i te punaha rokiroki me kitea ki runga i a raatau ma te whakamahi i te whakahau "huarahi maha -ll".
E ai ki , haere ki te tomokanga haere ki Storage >> rohe -> Rohe Hou ka whai i nga tohutohu mai i te waahanga "Whakapiri FCP Storage".
I muri i te whakarewatanga o te ruānuku, whakakiia nga mara e hiahiatia ana:
- ingoa — whakaturia te ingoa tautau
- Taumahi Rohe —Raraunga
- Momo rokiroki - Hongere muka
- Kaihautū hei Whakamahi — tohua he kaihautu kei te waatea te LUN e hiahiatia ana
I te rarangi o nga LUN, tohuhia te mea e hiahiatia ana e matou, pawhiria Tāpiri ko reira hoki OK. Mena e tika ana, ka taea e koe te whakatika i nga taapiri taapiri o te waahi rokiroki ma te paatene Tawhito Tawhito.
Whakaahuamata o te ruānuku mo te taapiri "Rohe Rokiroki"
I runga i nga hua o te ruānuku, me whiwhi tatou i tetahi waahi rokiroki hou, a me neke to tatou pokapū raraunga ki te mana UP, kua arawhiti ranei:
Ko nga whakaahua o te pokapū raraunga me nga waahi rokiroki kei roto:
Te hanga me te whirihora whatunga mo nga miihini mariko
Hononga ki nga tuhinga - Aratohu Whakahaere oVirt,
Whatunga, whatunga ranei, ka mahi ki te whakarōpū i nga whatunga arorau e whakamahia ana i roto i te hanganga mariko oVirt.
Hei taunekeneke i waenga i te urutau whatunga i runga i te miihini mariko me te urutau tinana i runga i te kaihautu, ka whakamahia nga atanga arorau penei i te piriti Linux.
Hei whakarōpū me te wehewehe i nga waka i waenga i nga whatunga, ka whirihorahia nga VLAN i runga i nga whakawhiti.
I te wa e hanga ana he whatunga arorau mo nga miihini mariko i roto i te oVirt, me tohu he tohu e rite ana ki te tau VLAN i runga i te whakawhiti kia taea ai e nga VM te whakawhitiwhiti korero ki a raatau, ahakoa ka rere i runga i nga waahanga rereke o te roopu.
Ko nga tautuhinga tuatahi o nga urutau whatunga ki nga kaihautu mo te hono i nga miihini mariko me mahi ki roto – whirihora atanga arorau bondxnumx, katahi ka mahia nga tautuhinga whatunga katoa ma te tomokanga whakahaere oVirt anake.
Whai muri i te hanga VM me te miihini-whakahau, i tua atu i te hanga aunoa o te pokapu raraunga me te tautau, i hanga aunoatia hoki he whatunga arorau hei whakahaere i ta tatou tautau - ovritmgmt, i hono ai tenei VM.
Mena e tika ana, ka taea e koe te tiro i nga tautuhinga whatunga arorau ovritmgmt ka whakatikahia, engari me tupato koe kei ngaro te mana o te hanganga oVirt.
Tautuhinga whatunga arorau ovritmgmt
Hei hanga i tetahi whatunga arorau hou mo nga VM auau, i te tomokanga whakahaere haere ki whatunga >> Ngā Whatunga >> New, me te ripa General taapirihia he whatunga me te ID VLAN e hiahiatia ana, ka tirotirohia te pouaka kei te taha o "Whatunga VM", ko te tikanga ka taea te whakamahi mo te taumahi ki tetahi VM.

Waihangahia he miihini mariko
Hononga tuhinga:
oVirt Aratohu Whakahaere Miihini Mariko ->
Whai muri i te utaina o te ahua whakaurunga me te OS ki oVirt, ka taea e koe te haere tika ki te hanga miihini mariko. He maha nga mahi kua oti, engari kua tae kee tatou ki te waahi whakamutunga, na te mea i timata ai enei mea katoa - te tiki i tetahi hanganga-a-hara mo te manaaki i nga miihini mariko tino waatea. Ko enei katoa he tino kore utu - kaore he pene kotahi i pau mo te hoko raihana rorohiko.
Hei hanga i tetahi miihini mariko me te CentOS 7, me tango te whakaahua whakaurunga mai i te OS.
Ka haere matou ki te tomokanga whakahaere, haere ki Whakauru >> Momo Motuhake, ka whakarewahia te ruānuku hanga VM. Whakakiia nga tawhā me nga mara katoa ka paato OK. He tino ngawari nga mea katoa mena ka whai koe i nga tuhinga.
Hei tauira, ka hoatu e ahau nga tautuhinga taketake me etahi atu taapiri o te VM e tino waatea ana, me te kopae kua hangaia, honoa ki te whatunga, me te puhipuhi mai i te ahua whakaurunga:
Whakaahuamata me nga tautuhinga VM tino waatea
Ka mutu te mahi me te ruānuku, kati, whakarewahia he VM hou me te whakauru i te OS ki runga.
Ki te mahi i tenei, haere ki te papatohu o tenei VM ma te tomokanga whakahaere:
Whakaahuatanga o nga tautuhinga tomokanga whakahaere mo te hono ki te papatohu VM
Hei hono atu ki te papatohu VM, me whirihora tuatahi koe i te papatohu i roto i nga taonga o te miihini mariko.
Whakaahuatanga o nga tautuhinga VM, ripa "Console".
Hei hono ki te papatohu VM ka taea e koe te whakamahi, hei tauira, .
Hei hono tika ki te papatohu VM i te matapihi tirotiro, me penei nga tautuhinga hononga ma te papatohu:
Whai muri i te whakaurunga o te OS ki runga i te VM, he mea tika kia whakauruhia he kaihoko manuhiri oVirt:
yum -y install epel-release
yum install -y ovirt-guest-agent-common
systemctl enable ovirt-guest-agent.service && systemctl restart ovirt-guest-agent.service
systemctl status ovirt-guest-agent.serviceNa, ko te hua o a maatau mahi, ka tino waatea te VM i hangaia, ara. ki te rahua te node tautau e rere ana, ka whakaara ano a oVirt i te konae tuarua. Ka taea hoki tenei VM te heke ki waenga i nga kaihautu tautau mo o raatau tiaki, mo etahi atu kaupapa ranei.
mutunga
Te ti'aturi nei au i taea e tenei tuhinga te whakaatu ko te oVirt he taputapu tino noa mo te whakahaere i nga hanganga mariko, ehara i te mea uaua ki te tohatoha - ko te mea nui ko te whai i etahi ture me nga whakaritenga e whakaahuahia ana i roto i te tuhinga me te tuhinga.
Na te nui o te tuhinga, kaore i taea te whakauru i nga mea maha ki roto, penei i te mahi-a-taahiraa o nga momo ruānuku me nga whakamarama taipitopito me nga whakaahua, nga whakatau roa o etahi whakahau, etc. Inaa, me tuhi he pukapuka katoa, kaore i te tino mohio na te mea ka puta nga putanga hou o nga rorohiko me nga mahi hou me nga huringa. Ko te mea nui ko te maarama ki te maataapono o te mahi tahi, me te whiwhi i te algorithm whanui mo te hanga i tetahi papaahara-whakaaro mo te whakahaere miihini mariko.
Ahakoa kua hangahia e matou he hanganga mariko, me ako inaianei ki te taunekeneke i waenga i ona huānga takitahi: kaihautu, miihini mariko, whatunga o roto, me te ao o waho.
Ko tenei mahinga tetahi o nga mahi matua a te punaha, kaiwhakahaere whatunga ranei, ka korerohia i roto i te tuhinga e whai ake nei - mo te whakamahi i nga pouara mariko VyOS i roto i nga hanganga whakaraerae o to tatou hinonga (i to whakaaro, ka mahi hei mariko. mihini i runga i ta maatau roopu oVirt).
