Virsh raira - Computer Networks yeSMEs

General index yeakateedzana: Computer Networks yeSMEs: Sumo

Mhoro shamwari!

Kana iwe wakatevera nesu tichiverenga zvinyorwa zvakaburitswa parizvino, iwe unenge waona kuti tiri kutevera nzira ine musoro, kuti tiwane chiteshi chebasa kana rabhoritari kumba, nerutsigiro rwakakodzera kuita chaiwo michina kana maseva atinozoshandisa mashoma mashoma masevhisi e Lan - Yemunharaunda Nharaunda Network Bhizinesi.

Isu tinofungidzira kuti iwe unoverenga:

• Computer Networks yeSMEs: Sumo
• Kuisirwa Workstation - Makomputa Networks eSMEs
• 6 Debian Desktops - Computer Networking yeSMEs
• Virtualization muDebian: Nhanganyaya - Computer Networks yeSMB
• Qemu-Kvm + Virt-Maneja pane Debian - Computer Networks yeSMMs
• ide-mirairo paDebian - Computer Networks yeSMB
• CentOS mumakomputa network eSMEs

Izvo zviri pamusoro zvinongedzo, pamwe nekunze zvinongedzo kune akasiyana mapeji uye masosi ane akapfuma ruzivo, akaisirwa mune yega yega chinyorwa, zvinopihwa nechinangwa chekuti iwe uwane ruzivo rwekutanga nezve dzakasiyana misoro yakafukidzwa.

Iyi posvo ndiko kuenderera kunonzwisisika kwenzira yakasarudzwa. Kuverenga kwako uye kudzidza kwako kunokutendera iwe kuve neruzivo rwepasirese nyika iri Virtualization kuburikidza Qemu-KVM uye chitoro chayo chikuru chemabhuku libvirt.

Virsh - Main mushandisi interface yekutarisa Virtual Domains

Isu tinoziva kubva pakuverenga kwakapfuura kuti Virtualization muLinux zvinoreva kugona kumhanyisa zviitiko zvakawanda zvehurongwa hwakasiyana hwekushanda, papuratifomu imwechete yehardware. libvirt ibhuku rekushandisa rakanyorwa mu mutauro C, iyo inotibvumidza kudyidzana nehunyanzvi hwekuona kwazvino vhezheni dzeLinux, uyezve neaya mamwe masisitimu anoshanda.

Tinogona kushandisa chirongwa ichi Virsh kugadzira, kumbomira, kudzima, rondedzero, uye mamwe akawanda mashandiro pane chaiwo madomeni uye hypervisors anovagamuchira. Zita rechirongwa rinoratidza kuti ipfupi ne «Virtualization Shiye»Kana Virtualization Raira processor.

Nenzira yakajairika tinogona kuitisa se:

virsh [OPTION] .... [NHAU] ...

• command: inogona kuva imwe yeiyo 215 mirairo zvakanyorwa gare gare
• domain: zita reiyo duraini kana muchina wemuchina, kana nhamba yekuzivisa ID yedomaini, kana UUID yedomeini.
• nharo: sarudzo yakanangana nemirairo yega yega

Pane akasarudzika akati wandei kumutemo wapfuura, senge mune zviitiko apo iwo murairo unoshanda pane ese madomeni, muchina, kana zvakananga paXen Hypervisor - XenHypervisor. Kusarudzika kwakadaro kunojekeswa pamirairo yega yega.

chitsamba: Kunyangwe chiri chakakodzera kuzivisa muchina chaiwo neinhamba yayo ID, iyi nhamba yenhamba ichagara ichidudzirwa sedomain ID, uye kwete sezita rayo.

• -c, –batanidza URI: Inobatanidza ku URI «Unifomu Resource Chitupa"- Unifomu Resource Chitupa, panzvimbo yeiyo default URI inova iyo yemuno hypervisor.
• -d, –debug NZIRA: Bvumira mameseji ekugadzirisa - debug, Kusvikira pakukosha kwenhamba LEVEL, nharo dzinoverengeka dzinogona kutora kukosha pakati pe0 na4. Chaizvoizvo 4 ndiyo kukosha kwekukosha.
• -e, - tambo yekutiza: Inoisa imwe nzira yekuteedzana kwehunhu nekuti patinodzvanya iyo «kiyiEsc«. Iyo yakasarudzika kuteedzana ndeye ^]. Mavara anotenderwa ndeaya: chero mavara arufabheti, @, [,], \, ^, _. Tinokurudzira usagadzirise yakasarudzika hunhu kutevedzera.
• -h, –batsira: Inorega chero imwe nharo uye inoita sekuti iwo murairo wakaitwa batsira.
• -k, –keepalive-nguva yekupindirana: Inoisa chikamu mumasekondi kutumira mameseji mhando chengetedza, kutarisa kana kubatana kuseva kuchiri kurarama. Kana kukosha kwe INTERVAL yakagadzirirwa ku 0, ipapo nzira iyi yekutarisa yakaremara.
• -K, –keepalive-kuverenga COUNT: Inoisa iyo nhamba yenguva meseji inogona kutumirwa chengetedza pasina kuwana mhinduro kubva kuseva, uye pasina kumaka kubatana sewakafa. Izvo hazvizove nemhedzisiro pane iyi sarudzo, kana iyo INTERVAL kukosha kwesarudzo yapfuura yakaiswa kuna 0.
• -l, -log FILE: Inotungamira iyo oparesheni dhigi kuburitsa kune iyo faira file.
• -q, –anyarara: Dzivisa rumwe ruzivo mumameseji. Silent mode.
• -r, – kuverenga chete: Kubatana kwekutanga kunosimbiswa mu Verenga chete. Zvakafanana nepatinoshandisa sarudzo –Readonly kuraira batanidza.
• -t, -nguva: Inoratidza nguva inopedzwa nemirairo yega yega.
• -v, –version = ipfupi: Regedza chero imwe nharo, uye ratidza chete raibhurari vhezheni libvirt chirongwa chinouya kubva Virsh.
• -V, –version = refu: Regedza chero imwe nharo uye ratidza raibhurari vhezheni libvirt chirongwa chinouya kubva Virsh uyezvezve, akasiyana hypervisors, vatongi - vatyairi, mhando dzemambure, nezvimwewo izvo zvinotsigirwa nemubatanidzwa.

Notes:

• Yakawanda yekuraira mashandiro Virsh, ngatitii chitoro chemabhuku libvirt kukwanisa kubatana nebasa libvltd muchiito.
• Mazhinji mirairo inoda kuti ivo vamhanyiswe nerombo rakanaka mudzi nekuda kwenzira dzekutaurirana dzainoshandisa kutaurirana neHypervisor. Kana ikamhanya neropafadzo dzeyakajairika mushandisi, inodzosera kukanganisa.
• Mazhinji emirairo inoshanda zvakafanana. Zvinogona kusarudzika zviri shutdown, setvcpus y setmem. Muzviitiko izvi, chokwadi icho Virsh dzosera iyo kukurumidza raira, zvingangoreve kuti chiito chakapedzwa zvinobudirira. Inofanirwa kuongororwa nguva nenguva kuti ione kuti kuvhiya kwapera paMuenzi - muenzi.

Kuti uwane rumwe ruzivo nezve zvemukati, ona murume virsh.
