Te hanga i tetahi hanganga IT e kore e he. Wāhanga 2. Te tāuta me te whirihora i te kāhui oVirt 4.3

He tuhinga tonu tēnei nō te tuhinga o mua – “Te hangahanga o nga hanganga IT e kore e he. Wāhanga 1 - Te Whakareri ki te Whakatakoto i tetahi Rōpū oVirt 4.3".

Ka hipokina e ia te tukanga tāutanga me te whirihoranga taketake o tētahi tautau oVirt 4.3 hei manaaki i ngā mīhini mariko e wātea ana, me te whakaaro kua oti kē ngā mahi tuatahi katoa mō te whakarite i te hanganga.

Kupu whakataki

Ko te whāinga matua o te tuhinga ehara i te mea he whakarato i ngā tohutohu taahiraa-i-te-taahiraa o te momo "Panuku -> Āe -> Mutu", engari hei whakamārama i ētahi o ngā āhuatanga motuhake o tōna tāutanga me tōna whirihoranga. Tērā pea kāore te tukanga whakatinanatanga o tō taupū e ōrite tonu ki te mea kua whakaahuatia i reira, nā ngā āhuatanga motuhake o tō hanganga me tō taiao, engari ka rite tonu ngā mātāpono whānui.

Mai i te tirohanga whaiaro, oVirt 4.3 Mō te mahi, he rite ki te VMware vSphere putanga 5.x, engari he pono, he āhuatanga whirihoranga me te whakahaere anō tōna.

Mō te hunga e hiahia ana, ka kitea ngā rerekētanga katoa i waenga i te RHEV (arā, ko oVirt) me te VMware vSphere i runga ipurangi, hei tauira. konei, engari ka tuhia tonu e au ētahi o ō rātou rerekētanga, ētahi rānei o ngā āhuatanga ōrite i waenganui i a rātou anō, i te haere tonu o te tuhinga.

E hiahia ana hoki ahau ki te whakarite poto i te whatunga mō ngā mīhini mariko. Ka whakatinanahia e oVirt tētahi mātāpono whakahaere whatunga rite tonu mō ngā mīhini mariko (e huaina ana i muri nei ko ngā VM) ki te VMware vSphere:

• с помощью стандартного Linux bridge (в VMware — Paerewa vSwitch), e rere ana i runga i ngā kaihautū mariko;
• mā te whakamahi i te Open vSwitch (OVS) (i roto i te VMware - vSwitch tohatoha) he pana mariko tohatoha e rua ngā wāhanga matua: he tūmau OVN pokapū me ngā kaiwhakahaere OVN i runga i ngā kaihautū whakahaeretia.

Необходимо отметить, что из-за простоты реализации, в статье будет описана настройка сетей в oVirt’е для ВМ с помощью стандартного Linux bridge, который является стандартным выбором, при использовании гипервизора KVM.

I tēnei whakaaro, he maha ngā ture matua mō te mahi tahi me te whatunga i roto i te tautau, he pai ake kia kaua e takahia:

• Me ōrite ngā tautuhinga whatunga katoa i runga i ngā kaihautū i mua i te tāpiri atu ki oVirt, engari ko ngā wāhitau IP anake.
• Kia noho te kaihautū ki raro i te mana o oVirt, he mea tino taunaki kia kaua e whakarerekē ā-ringa i ngā tautuhinga whatunga ki te kore koe e tino māia ki ō mahi, nā te mea ka hurihia noa e te kaihoko oVirt ki ō rātou tautuhinga o mua i muri i te tīmata anō i te kaihautū, te kaihoko rānei.
• Ko te tāpiri i tētahi whatunga hou mō tētahi VM, me te mahi tahi hoki me ia, me mahi anake mai i te papatohu whakahaere oVirt.

Kotahi anō te mea he kōrero nui — mō tētahi taiao tino kino (tino pāngia e ngā mate pūtea), ka tūtohutia tonu kia whakamahia te tautoko utu me te whakamahi Te Marikotanga o te Pōtae Whero 4.3I te wā e whakahaerehia ana te rōpū oVirt, tera pea ka ara ake ētahi raruraru, nō reira he mea tika kia rapu āwhina mā te hunga whai tohu i te wā e taea ai, kaua e ngana ki te whakatau i a koe anō.

Hei whakamutunga, tūtohutia I mua i te whakatinanatanga o tētahi taupū oVirt, pānuihia tuhinga whaimana, kia mōhio ki ngā ariā me ngā whakamāramatanga taketake, ki te kore ka uaua ki te pānui i te toenga o te tuhinga.

He mea nui ngā aratohu e whai ake nei hei mārama ki tēnei tuhinga me ngā mātāpono whakahaere o te rōpū oVirt:

• Aratohu Tāutanga oVirt
• Aratohu Mīhini Manaaki-Whaiaro oVirt
• Aratohu Whakahaere oVirt
  

Kāore i te tino rahi te pukapuka, ka taea e koe te ako i ngā mātāpono taketake i roto i te haora, e rua rānei, ā, mō te hunga e pai ana ki ngā taipitopito, e taunakihia ana kia pānuihia Ngā tuhinga hua mō te Red Hat Virtualization 4.3 — He rite tonu te RHEV me te oVirt.

Nō reira, ki te oti ngā tautuhinga taketake katoa mō ngā kaihautū, ngā pana, me ngā pūnaha rokiroki, ka haere tika tātou ki te whakatinanatanga o oVirt.

Wāhanga 2. Te Tāuta me te Whirihora i te Taupū oVirt 4.3

Hei ngāwari ake te tirotiro, ka whakarārangihia e au ngā wāhanga matua o tēnei tuhinga, me whakaoti kia rite ki te raupapa:

1. Te tāuta i te tūmau whakahaere oVirt
2. Te hanganga o tētahi pokapū raraunga hou
3. Te waihanga i tētahi rōpū hou
4. Te tāuta i ngā kaihautū tāpiri i roto i tētahi taiao e manaakihia ana e koe anō
5. Te Waihanga i tētahi Rohe Rokiroki
6. Te waihanga me te whirihora i ngā whatunga mō ngā mīhini mariko
7. Te waihanga i tētahi whakaahua tāutanga hei whakatū i tētahi mīhini mariko
8. Waihangahia he miihini mariko

Te tāuta i te tūmau whakahaere oVirt

Tūmau Whakahaere oVirt – koia te huānga tino nui o te hanganga oVirt, arā, he mīhini mariko, he kaihautū, he taputapu mariko rānei e whakahaere ana i te hanganga katoa oVirt.

Ko ōna ritenga tata ki te ao o te marikotanga:

• VMware vSphere - Tūmau vCenter
• Microsoft Hyper-V - Kaiwhakahaere Mīhini Mariko Pūnaha (VMM).

Hei tāuta i te tūmau whakahaere oVirt, e rua ā mātou kōwhiringa:

Kōwhiringa 1
Te whakatū i tētahi tūmau hei VM, hei kaihautū rānei i whakatapua.

He tino pai te mahi a tēnei kōwhiringa, engari mēnā ka mahi motuhake tētahi VM i te taupū, arā, kāore e whakarewahia i runga i tētahi kaihautū taupū hei mīhini mariko noa i raro i te mana whakahaere a KVM.

He aha e kore ai e taea te whakatakoto i tētahi VM pēnei ki ngā kaihautū taupū?

В самом начале процесса развёртывания управляющего сервера oVirt, у нас имеется дилемма — управляющую ВМ ставить нужно, но самого кластера фактически ещё нет, и поэтому что можно с ходу придумать? Правильно – установить KVM на будущий узел кластера, далее на нём создать виртуальную машину, например, с ОС CentOS и в ней развернуть oVirt engine. Это может делаться обычно из соображений полного контроля над такой ВМ, но это ошибочное намерение, потому что в таком случае, в дальнейшем 100% будут проблемы с такой управляющей ВМ:

• kāore e taea te neke i roto i te papatohu oVirt i waenga i ngā kaihautū taupū (ngā pona);
• i te wā e heke ana mā te whakamahi i ngā taputapu KVM hekenga wahine, kāore tēnei VM e wātea ana mō te whakahaere mai i te papatohu oVirt.
• kāore e taea te whakaatu i ngā kaihautū taupū i roto i Aratau Whakatikatika (aratau tiaki) mēnā ka nekehia e koe tēnei VM mai i te kaihautū ki te kaihautū mā te whakamahi i hekenga wahine.

Nō reira, me mahi i ngā mea katoa kia rite ki ngā ture—whakamahia he kaihautū motuhake mō te tūmau whakahaere oVirt, he VM motuhake rānei e whakahaere ana i runga, he pai ake rānei, whai i te kōwhiringa tuarua.

Kōwhiringa 2
Te tāuta i te Taputapu Mīhini oVirt ki runga i tētahi kaihautū taupū e whakahaerehia ana e ia.

Ka kiia tēnei kōwhiringa he tika ake, he pai ake hoki mō tā mātou take.
Kei raro nei ngā whakaritenga mō tētahi VM pēnei. Me tāpiri atu e au, me whai kia rua ngā kaihautū i roto i te hanganga e taea ai e te VM whakahaere te whakahaere kia kore ai e pāngia e ngā hapa. Me tāpiri atu anō, e ai ki taku kōrero i roto i ngā kōrero o te tuhinga o mua, kāore anō kia taea e au te tiki roro wehewehe i runga i tētahi rōpū oVirt o ngā kaihautū e rua, me te kaha ki te whakahaere i ngā VM miihini-hautū ki runga i aua mea.

Te tāuta i te taputapu miihini oVirt ki te kaihautū tuatahi o te rōpū

Hononga ki ngā tuhinga whaimana - Aratohu Mīhini Manaaki-Whaiaro oVirt, upoko "Te Whakatū i te Mīhini Whaiaro-Manaaki mā te Whakamahi i te Raina Whakahau»

E whakamārama ana te tuhinga i ngā whakaritenga me tutuki i mua i te whakatinanatanga o tētahi VM miihini-hautū, ā, e whakaahua ana hoki i te tukanga tāutanga me ngā taipitopito, nō reira kāore he take motuhake ki te whakahua anō i te kupu, nō reira ka arotahi tātou ki ētahi taipitopito nui.

• I mua i te tīmatanga o tētahi mahi, kia tino whakahohea te tautoko mariko i ngā tautuhinga BIOS o te kaihautū.
• Tāutahia te mōkihi tāuta hosted-engine 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 whakarewahia e mātou te tukanga whakatinanatanga o te oVirt Hosted Engine ki te kaihautū i roto i te mata (ka taea e koe te puta atu mā te Ctrl-A + D, katia mā te Ctrl-D):

screen
hosted-engine --deploy

Ki te hiahiatia, ka taea e koe te whakahaere i te tāutanga me te kōnae urupare kua whakaritea i mua:

hosted-engine --deploy --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-ohe.conf

• I te wā e whakatinana ana i te miihini-hosted, ka tohua e mātou ngā tawhā katoa 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 tāuta i tētahi VM e wātea ana me tētahi miihini manaaki, i hangaia e mātou he LUN nama 4 motuhake me te rahi o te 150 GB i runga i te pūnaha rokiroki i mua, ā, i tukuna atu ki ngā kaihautū taupū - tirohia i roto i Tuhinga o mua.

I tirohia anō hoki e mātou tōna kitea i runga i ngā kaihautū:

multipath -ll

  `- 18:0:0:4  sdj 8:144 active ready running

• He māmā noa iho te tukanga whakatinanatanga o te miihini manaaki, ā, i te mutunga, me whiwhi tātou i tētahi karere e rite ana ki tēnei:

[ INFO  ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20191129131846.conf'

Tirohia te wātea o ngā ratonga oVirt i runga i te kaihautū:

Mena kua tika ngā mea katoa, kātahi ka oti te tāutanga, haere ki te pūtirotiro tukutuku. https://ovirt_hostname/ovirt-engine mai i te rorohiko a te kaiwhakahaere, kātahi ka pāwhiri i te [Pouaka Whakahaere].

Whakaahuamata o te "Tororanga Whakahaere"

Mā te whakauru i tō takiuru me tō kupuhipa (i whakatakotoria i te wā tāutanga) ki te matapihi e whakaaturia ana i te whakaahua mata, ka haria koe ki te papatohu whakahaere o te Open Virtualization Manager, ka taea e koe te mahi i ngā mahi katoa me tō hanganga mariko:

1. tāpirihia he pokapū raraunga
2. tāpirihia me te whirihora i tētahi rōpū
3. tāpiri me te whakahaere i ngā kaihautū
4. tāpirihia ngā wāhi rokiroki, ngā Rohe Rokiroki rānei mō ngā kōpae mīhini mariko
5. tāpiri me te whirihora i ngā whatunga mō ngā mīhini mariko
6. tāpiri me te whakahaere i ngā mīhini mariko, ngā whakaahua tāutanga, ngā tauira VM

Ka matapakihia ēnei mahi katoa i raro nei, ko ētahi he tuhinga nui, ko ētahi he taipitopito ake, he rerekē hoki ngā āhuatanga.
Engari tuatahi, ka tūtohu ahau kia pānuihia tēnei tāpiringa, he mea tino whai hua tēnei ki te tini.

Tāpiri

1) Ko te tikanga, ki te mea he hiahia pēnei, kāore he mea e aukati i a koe ki te tāuta i te hypervisor KVM ki runga i ngā pona tautau i mua i te whakamahi i ngā mōkihi tahua и qemu-kvm (ranei qemu-kvm-ev) te putanga e hiahiatia ana, ahakoa i te wā e whakatū ana i tētahi pūnga tautau oVirt, ka taea e ia te mahi i tēnei.

Engari mena tahua и qemu-kvm Mena i tāuta e koe tētahi putanga ehara i te mea hou rawa, ka whiwhi pea koe i te hapa e whai ake nei i te wā e whakatinana ana te miihini manaaki:

error: unsupported configuration: unknown CPU feature: md-clear

Ara, he mea tika kia whai putanga kua whakahoutia tahua me te tiakitanga mai i MDS, e tautoko ana i te kaupapa here e whai ake nei:

<feature policy='require' name='md-clear'/>

Tāutahia te libvirt v.4.5.0-10.el7_6.12, me te tautoko md-clear:

yum-config-manager --disable mirror.centos.org_centos-7_7_virt_x86_64_libvirt-latest_

yum install centos-release-qemu-ev
yum update
yum install qemu-kvm qemu-img virt-manager libvirt libvirt-python libvirt-client virt-install virt-viewer libguestfs libguestfs-tools dejavu-lgc-sans-fonts virt-top libvirt libvirt-python libvirt-client

systemctl enable libvirtd
systemctl restart libvirtd && systemctl status libvirtd

Te tirotiro mō te tautoko 'md-clear':

virsh domcapabilities kvm | grep require
      <feature policy='require' name='ss'/>
      <feature policy='require' name='hypervisor'/>
      <feature policy='require' name='tsc_adjust'/>
      <feature policy='require' name='clflushopt'/>
      <feature policy='require' name='pku'/>
      <feature policy='require' name='md-clear'/>
      <feature policy='require' name='stibp'/>
      <feature policy='require' name='ssbd'/>
      <feature policy='require' name='invtsc'/>

I muri i tēnei, ka taea e koe te haere tonu ki te tāuta i te miihini manaaki.

2) I roto i te oVirt 4.3, te aroaro me te whakamahinga o te pareārai ahi firewalld he whakaritenga ā-ture.

Mena ka whiwhi mātou i te hapa e whai ake nei i te wā e whakatinanahia ana te VM mō te miihini-hosted:

[ 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=1608467

Kātahi ka hiahia koe ki te whakaweto i tētahi atu pareārai ahi (mēnā kei te whakamahia tētahi), kātahi ka tāuta 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-zones

Ā muri ake nei, ina tāutahia te kaihoko ovirt ki tētahi kaihautū hou mō te taupū, ka whirihorahia ngā tauranga e hiahiatia ana i roto i firewalld aunoa.

3) Te whakaara anō i te kaihautū me te VM e rere ana i runga me te miihini e manaakihia ana.

Ka rite ki te tikanga, hono 1 и hono 2 i runga i ngā tuhinga whakahaere.

Ko te whakahaere katoa o te miihini VM manaaki ka mahia ANAKE mā te whakamahi i te whakahau miihini-hautū mō te kaihautū e mahi ana ia, mō wahine me wareware tātou, me te meka hoki ka taea e koe te hono atu ki tēnei VM mā SSH me te whakahaere i te whakahau "tutakina".

Te tukanga mō te whakanoho i tētahi VM ki te aratau tiaki:

Ka whakaara anō mātou i te kaihautū me te kaihoko miihini manaaki, ā, ka mahi ki a ia i tā mātou e hiahia ana.

I muri i te whakaara anō, tirohia te tūnga o te VM me te miihini manaaki:

hosted-engine --vm-status

Ki te kore e tīmata tā mātou VM me te hosted-engine, ā, ka kite mātou i ngā hapa ōrite i roto i te rangitaki ratonga:

4) Te tango i te miihini manaaki me nga mea katoa e hono ana ki a ia.

I ētahi wā me tango tika te miihini manaaki kua tāutahia i mua - hono ki te tuhinga whakahaere.

Ka whakahaerehia noa e mātou te whakahau i runga i te kaihautū:

/usr/sbin/ovirt-hosted-engine-cleanup

Muri iho, ka tangohia e mātou ngā mōkihi kāore e hiahiatia, me te tārua i ngā whirihoranga katoa i mua, ki te mea e tika ana:

yum autoremove ovirt* qemu* virt* libvirt* libguestfs 

Te hanganga o tētahi pokapū raraunga hou

Ngā tuhinga āwhina — Aratohu Whakahaere oVirt. Upoko 4: Ngā Pokapū Raraunga

Tuatahi, me tautuhi tātou he aha te mea pokapū raraunga (Ka tangohia e au i te āwhina) he hinonga arorau e tautuhi ana i tētahi huinga rauemi e whakamahia ana i roto i tētahi taiao motuhake.

He momo ipu te pokapū raraunga, kei roto ko:

• ngā rauemi arorau i roto i te ahua o ngā tautau me ngā kaihautū
• ngā rauemi whatunga taupū i roto i te ahua o ngā whatunga arorau me ngā urutau ā-tinana i runga i ngā kaihautū,
• ngā rauemi rokiroki (mō ngā kōpae VM, ngā tauira, ngā whakaahua) i roto i te āhua o ngā wāhi rokiroki (Ngā Rohe Rokiroki).

Tērā pea kei roto i tētahi pokapū raraunga he maha ngā tautau kei roto ko ngā kaihautū maha me ngā mīhini mariko e whakahaerehia ana i runga, ā, tērā pea he maha hoki ngā wāhi rokiroki e hono ana ki taua pokapū raraunga.
Tērā pea he maha ngā pokapū raraunga, e mahi takitahi ana. Mā Ovirt ka taea te whakamahi i ngā whakaaetanga e hangai ana ki ngā tūranga, ā, ka taea hoki te whakamahi i ngā whakaaetanga kua whakaritea, i te taumata pokapū raraunga me ngā huānga arorau takitahi.

Te Waihanga i tētahi Rohe Rokiroki

Hononga tuhinga: Aratohu Whakahaere oVirt, Upoko 8: Te Rokiroki.

Rohe Rokiroki, he wāhi rokiroki rānei, he wāhi pokapū mō te penapena i ngā kōpae mīhini mariko, ngā whakaahua tāutanga, ngā tauira, me ngā whakaahua poto.

Ka taea te hono i ngā wāhi rokiroki ki te pokapū raraunga mā te whakamahi i ngā kawa maha, ngā pūnaha kōnae taupū me ngā pūnaha kōnae whatunga.

E toru ngā momo wāhi rokiroki a oVirt:

• Rohe Raraunga – mō te penapena i ngā raraunga katoa e pā ana ki ngā mīhini mariko (kōpae, tauira). Kāore e taea te tohatoha i te Rohe Raraunga i waenga i ngā pokapū raraunga rerekē.
• Rohe ISO (momo wāhi rokiroki tuku iho) – mō te penapena i ngā whakaahua tāutanga OS. Ka taea te tohatoha i te Rohe ISO i waenga i ngā pokapū raraunga rerekē.
• Kaweake Rohe (momo wāhi rokiroki tuku iho) – mō te rokiroki rangitahi o ngā whakaahua kua nekehia i waenga i ngā pokapū raraunga.

I tēnei take, ka whakamahia e te wāhi rokiroki me te momo Rohe Raraunga te Fibre Channel Protocol (FCP) hei hono atu ki ngā LUN i runga i te pūnaha rokiroki.

Mai i te tirohanga a oVirt, ina whakamahia te rokiroki (FC, iSCSI rānei), he kōpae arorau ia kōpae mariko, ia whakaahua, ia tauira rānei.
Ka kohia ngā pūrere poraka (i runga i ngā kaihautū taupū) mā te whakamahi i te Rōpū Rōrahi, kātahi ka wehea mā te whakamahi i te LVM ki ngā rōrahi arorau e whakamahia ana hei kōpae mariko mō ngā VM.

Ka kitea ēnei rōpū katoa me te maha o ngā rōrahi LVM i runga i te kaihautū taupū mā te whakamahi i ngā whakahau etc и LvsKo te tikanga, ko ngā mahi katoa me ēnei kōpae me mahi noa mai i te papatohu oVirt, engari i ngā wā motuhake.

E rua ngā momo kōpae mariko mō ngā VM: QCOW2, RAW rānei. Ka taea te whakamahi i ngā kōpae "kikokore"ranei"matotoru". Ka hangaia tonutia ngā whakaahua poto hei "kikokore".

He tino arorau te huarahi e whakahaerehia ai ngā rohe rokiroki, arā, ngā wāhi rokiroki e uru atu ana mā te Fibre Channel (FC): he rōrahi arorau motuhake tō ia kōpae mariko VM, ka taea te tuhi e te kaihautū kotahi anake. Mō ngā hononga FC, ka whakamahia e oVirt tētahi mea rite ki te LVM whakarōpū.

Ka taea te neke i ngā mīhini mariko kei roto i te wāhi rokiroki kotahi i waenga i ngā kaihautū nō te taupū kotahi.

E kitea ana i te whakaahuatanga, he rite tonu te tikanga o te tautau i roto i te oVirt, he rite ki te tautau i roto i te VMware vSphere, i te Hyper-V rānei: he rōpū arorau o ngā kaihautū, he rite tonu te hanganga taputapu, ā, he rite tonu te rokiroki mō ngā kōpae mīhini mariko.

Me neke tika tātou ki te waihanga i tētahi wāhi rokiroki mō ngā raraunga (ngā kōpae VM), nā te mea ki te kore, kāore e taea te tīmata i te pokapū raraunga.
Me whakamahara atu ahau me kitea ngā LUN katoa e whakaaturia ana ki ngā kaihautū taupū i runga i te pūnaha rokiroki mā te whakamahi i te whakahau "ara maha -ll".

E ai ki tuhinga, ka haere mātou ki te tomokanga, ka tomo mātou Storage >> rohe -> Rohe Hou ā, whai i ngā tohutohu i te wāhanga "Tāpiri Rokiroki FCP".

I muri i te whakarewatanga o te ruānuku, whakakīia ngā āpure e hiahiatia ana:

Te waihanga me te whirihora i ngā whatunga mō ngā mīhini mariko

Hononga tuhinga: Aratohu Whakahaere oVirt, Upoko 6: Ngā Whatunga Arorau

Ko ngā whatunga, arā, ngā whatunga matihiko, e whakamahia ana hei whakarōpū i ngā whatunga arorau e whakamahia ana i roto i te hanganga mariko oVirt.

Для взаимодействия сетевого адаптера на виртуальной машине, с физическим адаптером на хосте, используются логические интерфейсы типа Linux piriti

Hei whakarōpū me te wehewehe i ngā waka i waenga i ngā whatunga, ka whirihorahia ngā VLAN ki runga i ngā pana.

I te wā e hangaia ana he whatunga arorau mō ngā mīhini mariko i roto i te oVirt, me tuku he ID e ōrite ana ki te tau VLAN i runga i te pana kia taea ai e ngā VM te whakawhitiwhiti kōrero tetahi ki tetahi, ahakoa kei te whakahaerehia i runga i ngā pona taupū rerekē.

Ko ngā tautuhinga tuatahi o ngā urutau whatunga i runga i ngā kaihautū mō te hono i ngā mīhini mariko i tika kia mahia i roto i Tuhinga o mua – kua whirihorahia te atanga arorau here1, ko ngā tautuhinga whatunga katoa me mahi mā te tomokanga whakahaere oVirt anake.

I muri i te waihangatanga o tētahi VM me tētahi miihini manaaki, hei tāpiritanga ki te waihangatanga aunoa o tētahi pokapū raraunga me tētahi taupū, i hangaia aunoatia hoki tētahi whatunga arorau mō te whakahaere i tā mātou taupū – ovritmgmt, i honoa ai tēnei VM ki.

Ki te hiahiatia, ka taea e koe te tiro i ngā tautuhinga whatunga arorau ovritmgmt me te whakarerekē i aua mea, engari me tūpato kei ngaro te mana whakahaere o te hanganga oVirt.

I muri i te utaina o te ahua tāutanga OS ki roto i te oVirt, ka taea e koe te haere tonu ki te waihanga i te mīhini mariko. He nui ngā mahi kua oti, engari kua tae kē tātou ki te wāhanga whakamutunga, ko te whāinga i tīmata ai: te waihanga i tētahi hanganga e ātete ana ki ngā hapa hei manaaki i ngā mīhini mariko e wātea ana. Ā, he kore utu katoa ēnei—kāore he pene kotahi i pau ki te hoko raihana pūmanawa.

Ko tāku tumanako kua whakaatu mai tēnei tuhinga he taputapu whakahaere hanganga mariko tino kaha a oVirt, ehara i te mea uaua ki te whakatinana—mēnā ka whai koe i ngā ture me ngā whakaritenga kua whakarārangihia i roto i te tuhinga me ngā tuhinga.

Nā te rahi o te tuhinga, kāore i taea te whakauru i ngā mea maha, pērā i ngā tohutohu taahiraa-i-te-taahiraa mō te whakaoti i ngā ruānuku maha me ngā whakamārama taipitopito me ngā whakaahua mata, ngā putanga whakahau roa, me ērā atu mea. Inaa, me whai pukapuka katoa tēnei, kāore i te tino whai hua i te mea kei te tukuna tonutia ngā putanga pūmanawa hou me ngā auahatanga me ngā huringa. Ko te mea nui ko te mārama ki te mahi tahi o ngā mea katoa me te whakawhanake i tētahi raupaparorohiko whānui mō te waihanga i tētahi tūāpapa whakahaere mīhini mariko e manawanui ana ki ngā hapa.

Ahakoa kua waihangahia e tātou he hanganga mariko, me whakaako e tātou kia taunekeneke i waenga i ōna ake huānga takitahi—ngā kaihautū, ngā mīhini mariko, ngā whatunga ā-roto—me te ao o waho hoki.

Ko tēnei tukanga tētahi o ngā mahi matua a te kaiwhakahaere pūnaha, a te kaiwhakahaere whatunga rānei, ka kōrerotia i roto i te tuhinga e whai ake nei – mō te whakamahinga o ngā pouara mariko VyOS i roto i te hanganga ātete-hapa o tā mātou hinonga (e ai ki tāu i whakaaro ai, ka rere hei mīhini mariko i runga i tā mātou taupū oVirt).
