Faateleina le manatua pe a manaomia e ala i le suia o le fuaiupu lea.
vjunos-sw1 5242880 5242880 4
O le example faʻaalia le manatuaga le lelei e manaʻomia e le vJunos-switch. O le manatua fa'aletonu e lava mo le tele o talosaga. E mafai ona e faʻateleina le tau pe a manaʻomia. O loʻo faʻaalia ai foi le igoa o le vJunos-switch patino o loʻo faʻatupuina, o le vjunos-sw1 i lenei tulaga. 6. Fa'ailoa le igoa ma le nofoaga o lau vJunos-switch image e ala i le suia o le XML file e pei ona faaalia i le example.
<disk device=”disk” type=”file”> file=”/root/vjunos-sw1-live.qcow2″/>
E tatau ona e tu'uina atu i vJunos VM ta'itasi i luga o le 'au fa'atasi ma lana lava ata fa'apitoa QCOW2. E manaʻomia lenei mea mo libvirt ma QEMU-KVM.

7. Fausia le ata tisiki. # ./make-config.sh E talia e le vJunos-switch se faʻatulagaga muamua e ala i le faʻafesoʻotaʻi o se tisiki lona lua i le faʻataʻitaʻiga VM o loʻo i ai le faʻatulagaga. Fa'aoga le fa'amatalaga tu'u mai make-config.sh e fai ai le ata tisiki. O le XML file faʻasino i lenei taʻavale faʻatulagaina e pei ona faʻaalia i lalo:
<disk device=”disk” type=”file”> file= ”/root/config.qcow2″/>
FAAMANATU: Afai e te le manaʻo i le faʻatulagaga muamua, ona aveese lea o le stanza o loʻo i luga mai le XML file.
8. Seti le pulega Ethernet uafu.
O lenei example fa'atagaina oe e fa'afeso'ota'i i le VCP "fxp0" o le fa'atonuga lea o le taulaga mai fafo o le 'au'aunaga talimalo lea e nofo ai le vJunos-switch. E mana'omia le i ai o se tuatusi IP e mafai ona fa'aogaina mo le fxp0, pe ala i le DHCP server po'o le fa'aogaina o le fa'atulagaina o le CLI. O le "eth0" i le stanza o loʻo i lalo e faʻatatau i le 'auʻaunaga talimalo talimalo lea e maua ai le fesoʻotaʻiga i le lalolagi i fafo ma e tatau ona fetaui ma le igoa o lenei atinaʻe i luga o lau 'auʻaunaga talimalo. Afai e te le o faʻaaogaina le Dynamic Host Configuration Protocol (DHCP), a maeʻa le vJunos-switch i luga ma faʻagaoioia, telnet i lona faʻamafanafanaga ma faʻapipiʻi le tuatusi IP mo le "fxp0" faʻaaoga le CLI configuration e pei ona faʻaalia i lalo:

Fa'aaga le SSH i le VCP pulega uafu. # seti auaunaga faiga ssh root-login faatagaina poloaiga. 10. Fausia se alalaupapa Linux mo taulaga taʻitasi e te faʻamaonia i le XML file.
O igoa o le uafu o lo'o fa'amaonia i le stanza o lo'o mulimuli mai. O le tauaofiaga mo le vJunos-switch o le faʻaaogaina lea o le ge-0xy lea e faʻamaonia ai e le "xy" le numera o le taulaga. I le example, ge-000 ma ge-001 o numera o le taulaga. O nei numera o le taulaga o le a fa'afanua i le Junos ge-0/0/0 ma le ge-0/0/1 feso'ota'iga. E pei ona taʻua muamua, e tatau ona e fatuina se alalaupapa Linux mo taulaga taʻitasi e te faʻamaonia i le XML file. 11. Tuuina atu se numera tulaga fa'amafanafana fa'amafanafanaga mo vJunos ta'itasi-sui i lau 'au'aunaga talimalo. I le example, o le tulaga tulaga ese faamafanafanaga taulaga numera o le “8610”.

Aua le suia le smbios stanza nei. E taʻu atu i vJunos o se vJunos-sui.
12. Fausia vJunos-sw1 VM fa'aaoga le vJunos-sw1.xml file. # virsh fatuina vjunos-sw1.xml
O le faaupuga "sw1" e faʻaaogaina e faʻaalia ai o le muamua vJunos-switch VM o loʻo faʻapipiʻiina. VMs mulimuli ane e mafai ona faaigoa vjunos-sw2, ma vjunos-sw3 ma isi.
O le iʻuga, ua faia le VM ma faʻaalia le savali o loʻo i lalo:
Domain vjunos-sw1 na faia mai le vjunos-sw1.xml 13. Siaki /etc/libvirt/qemu.conf ma fa'amuta laina XML nei pe afai o nei laina
fa'ailoa mai. O nisi exampo tau aoga o lo'o tu'uina atu i lalo. Aveese fa'amatalaga laina fa'amaonia.

aveese fa'amatalaga lenei laina
#
#group = “a’a” <<<< aveese fa’amatalaga le laina lea
14. Toe amata le libvirtd ma toe fai le vJunos-switch VM. # systemctl toe amata le libvirtd
15. Tapuni ma le saogalemu le vJunos-switch o loʻo faʻapipiʻiina i luga o le Host Server (pe a manaʻomia). Fa'aaoga le # virsh shutdown vjunos-sw1 poloaiga e tapuni vJunos-switch. A e faʻatinoina lenei laasaga, o se faʻailoga tapuni e lafo i le vJunos-switch instance e mafai ai ona tapunia ma le alofa.
O lo'o fa'aalia le fe'au lea.
O lo'o tapunia le vaega 'vjunos-sw1'
