Installa la VM dalla riga di comando con virt-install

Dichiarazione di non responsabilità:

Ora uso virt-managerper creare e gestire la mia VM ed è davvero un salvavita. Può essere utilizzato in remoto (da una terza macchina, in genere la workstation) se l'host non ha una visualizzazione grafica.

Le occorrenze vncnelle esercitazioni di installazione che ho trovato mi hanno fatto pensare che la procedura "consigliata" richiedesse elementi X su host, guest o entrambi. Assolutamente no. Errore mio. Se ti trovi nella stessa situazione, pensaci due volte prima di provare a installare la VM dalla riga di comando.

Sto provando a installare una VM Debian in un host Debian usando virt-installe non so come passarla all'immagine .iso.

virt-install --connect qemu:///system --virt-type kvm --name prod --ram 6144 --disk /srv/vm/prod.qcow,format=qcow2,size=10 --location=/home/jerome/debian-8.0.0-amd64-netinst.iso --network bridge=br0 --os-type linux --os-variant debianwheezy --extra-args='console=tty0 console=ttyS0,115200n8 serial'

If it was, you can restart your domain by running:

Le soluzioni che ho visto sembrano piuttosto distorte, come usare apache per servire localmente l'immagine .iso come se provenisse da un posto lontano.

• Linux Mint 14: installa Ubuntu 12.10 Server in KVM tramite CLI (no GUI)
• [Xen-users] installa un vm con virt-install (è Xen ma sembra che sia lo stesso problema comunque.

Non posso credere che sia così complicato. È?

man virt-install dice:

If you want to use those options with CDROM media, you have a few options:

         * Run virt-install as root and do --location ISO

         * Mount the ISO at a local directory, and do --location DIRECTORY

         * Mount the ISO at a local directory, export that directory over local http, and do --location http://localhost/DIRECTORY

Non è quello che sto facendo?

Qualcuno dice che ha spostato .iso su / cdrom e ha funzionato, ma non capivo esattamente cosa facesse e non potevo riprodurlo.

Non posso usare --cdrominvece di --locationcome in questa domanda perché --extra-argsfunziona solo se specificato con --location.

virt-install --connect qemu:///system --virt-type kvm --name prod --ram 6144 --disk /srv/vm/prod.qcow,format=qcow2,size=10 --cdrom=/home/jerome/debian-8.0.0-amd64-netinst.iso --network bridge=br0 --os-type linux --os-variant debianwheezy --extra-args='console=tty0 console=ttyS0,115200n8 serial'
ERROR    --extra-args only work if specified with --location. See the man page for examples of using --location with CDROM media

Funziona con, --location http://ftp.us.debian.org/debian/dists/stable/main/installer-amd64/ma non è un peccato farlo quando un'immagine .iso è disponibile localmente?

• Perdita di tracciabilità: non è possibile riprodurre in seguito, accertandosi di ottenere esattamente la stessa fonte.

• Uso moltiplicato della larghezza di banda da server / mirror.

• Necessità di accesso a Internet.

• Più lentamente.

Suppongo virt-installche non supporti le immagini ISO del netinst Debian con --location(ma in qualche modo Ubuntu supportato?).

Per avviare un kernel --extra-args, è virt-installnecessario disporre di quel kernel e dei file initrd corrispondenti. --cdromsemplicemente collega ISO all'unità CD del guest, che non è sufficiente per funzionare --extra-args.

Se vuoi usarlo --extra-args, ti consiglio di usare i file kernel / initrd "netboot" specificando l'URL di installazione Debian del tuo mirror più vicino, come --location http://ftp.us.debian.org/debian/dists/stable/main/installer-amd64/descritto nel manuale.

Questo metodo ha funzionato per me:

virt-install --name=centos \
--memory=8196 --vcpus=2 \
--location=/var/lib/libvirt/images/CentOS-7-x86_64-Minimal-1511.iso \
--disk /var/lib/libvirt/images/centos7.qcow2,device=disk,bus=virtio,size=8 \
--network bridge:br0 \
--os-type=linux  \
--nographics \
--extra-args='console=tty0 console=ttyS0,115200n8 serial'

La differenza sta nei file ISO utilizzati.

Non è correlato al modo in cui virt-installviene utilizzato ( --locationutilizzato con l'URL http rispetto --locational percorso utilizzato per un file iso locale).

Ecco un comando che funziona quando si usano i repository online di Debian come --location(incluso ottenere l'output per completare l'installazione fino al primo avvio (quindi sono necessari altri due passaggi per entrare finalmente nella nuova VM, ma questa è un'altra storia):

virt-install --virt-type kvm --name test8 --memory 2048 --disk path=/var/lib/libvirt/images/test8-1.qcow2,size=5 --disk path=/var/lib/libvirt/images/test8-2.qcow2,size=2 --location http://ftp.at.debian.org/debian/dists/stable/main/installer-amd64/ --graphics none --extra-args='console tty0 console=ttyS0,115200n8 serial'

Si può prendere l'esatto stesso comando, ma usando i suddetti file di CentOS ISO come --location, e funziona così (tranne che il collegamento con la console seriale non sembra funzionare in un primo momento, ma in linea di principio l'avvio di installazione utilizzando --location e il file ISO):

virt-install --virt-type kvm --name test8 --memory 2048 --disk path=/var/lib/libvirt/images/test8-1.qcow2,size=5 --disk path=/var/lib/libvirt/images/test8-2.qcow2,size=2 --location /softwarestorage/CentOS-7-x86_64-Minimal-1511.iso --graphics none --extra-args='console tty0 console=ttyS0,115200n8 serial'

L'output è:

Ma se usi il file ISO Debian per --location, ottieni l'errore:

virt-install --virt-type kvm --name test8 --memory 2048 --disk path=/var/lib/libvirt/images/test8-1.qcow2,size=5 --disk path=/var/lib/libvirt/images/test8-2.qcow2,size=2 --location /softwarestorage/debian-8.5.0-amd64-CD-1.iso --graphics none --extra-args='console tty0 console=ttyS0,115200n8 serial'

ERROR    Could not find an installable distribution at '/softwarestorage/debian-8.5.0-amd64-CD-1.iso'
The location must be the root directory of an install tree.
Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
  virsh --connect qemu:///system start test8
otherwise, please restart your installation.

IMHO questo dimostra che manca qualcosa / qualcosa di "sbagliato" nell'ISO Debian (non sono sicuro al momento da dove l'ho preso, ma forse qualcuno può scaricarne uno nuovo e ripetere i test ...)

Quanto segue ha funzionato per me installando Debian 10 da un sistema host Ubuntu 16.04:

cd /usr/share/virt-manager/virtinst/

È brutto, specialmente se vuoi usare i file kickstart, ma ecco cosa ho fatto per avviare questo processo:

root@kvm:~# virt-install -n rhce2 -r 2048 --vcpus=1 --os-variant=rhel6 --accelerate -v --disk path=/var/lib/libvirt/images/RHCE2.img,size=100 -l /root/centos6.7.iso -x "ks=./ks1.cfg" --nographics

La differenza fondamentale tra quello che ho fatto e quello che hai fatto è che ho usato il --locationtag ( -lin breve) per indicare il mio iso.

recentemente ha riscontrato questo problema. Ho semplicemente usato un programma di installazione remoto con --location. Devo sottolineare che, a seconda della tua versione virsh, i collegamenti per gli installatori remoti potrebbero non essere aggiornati nella pagina man.

Ho appena seguito questo esempio e tutto è andato liscio: https://www.packet.com/developers/guides/kvm-and-libvirt/

Nel mio caso, ho cambiato 'xenial' per 'bionic' in http://us.archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/ e l'installazione è andata a buon fine. Andando a utilizzare questo metodo ogni volta da ora in poi.
