Proxmox: Importar imagen QCOW2
Si os encontráis con ficheros de imagen de máquina virtual QCOW2 y no sabéis como importarlo en Proxmox os lo explico en unos pocos pasos.
Por defecto, no vamos a poder usar las imágenes QCOW2 directamente en una de nuestras máquinas virtuales, tendremos que convertirla para que Proxmox trabaje con ella.
El comando, que voy a explicar, sería:
qm importdisk 101 fichero.qcow2 local-lvm
- “qm importdisk” es el comando de Proxmox
- “101” es el ID de la máquina virtual donde importaremos el disco
- “fichero.qcow2” es el nombre del disco QCOW2
- “local-lvm” es el volumen donde lo vamos a dejar
Ahora detallo los pasos que yo voy a utilizar para que os sea más fácil.
De primeras, me conecto vía SSH a uno de mis nodos:

1 2 3 4 5 6 7 8 9 10 11 12 |
MacBook-Pro-de-Raul:~ raulunzue$ ssh root@192.168.2.50 root@192.168.2.50's password: Linux pve2 5.4.65-1-pve #1 SMP PVE 5.4.65-1 (Mon, 21 Sep 2020 15:40:22 +0200) x86_64 The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

Lo primero que tenéis que saber es donde tenéis que copiar el disco. Normalmente, esta es la ruta de los Storages en Proxmox:
|
1 2 |
root@pve2:~# ls /mnt/pve/ CEPH01/ NAS/ |
Así que subís a la ruta el disco, ya sea con Filezilla, SSH o como os resulte más cómodo. En mi caso os lo dejo por SSH con SCP:
|
1 2 3 |
MacBook-Pro-de-Raul:Downloads raulunzue$ scp fedora-coreos-32.20200907.3.0-qemu.x86_64.qcow2 root@192.168.2.50:/mnt/pve/NAS/images root@192.168.2.50's password: fedora-coreos-32.20200907.3.0-qemu.x86_64.qcow2 79% 1394MB 106.8MB/s 00:03 ETA |
Verificamos que se ha copiado en la ruta:
|
1 2 |
root@pve2:/mnt/pve/NAS/images# ls @eaDir fedora-coreos-32.20200907.3.0-qemu.x86_64.qcow2 |
Ahora usaré una máquina virtual para asignarle el disco, en este caso el ID es el 122:
Así que lanzo el comando del que hemos hablado al principio:

Y se la asignará a la máquina virtual:
Yo he cambiado el boot para que arranque del disco recién montado, que es un Fedora CoreOS, lo compruebo:
Espero os parezca interesante…ya que es gratis, comparte ;P

Hola Raul, me funciono a la perfección, mil gracias por el post, aunque tengo una duda, una vez importados los qcow2 y asignados a la VM, puedo eliminar los Qcow2 que fueron importados para liberar espacio en disco?
Mil gracias de antemano
Hola Germán, Gracias. Si, han importado puedes borrarlo. Un saludo
hola buenas tardes, realice el proceso y todo bien, el detalle fue que al iniciar la MV con windows me da un pantallazo azul, y no se que error me lanza y no tengo como validar
hol araul tengo un problema en proxomox la unidad logica lvm-thin esta superblock como puedo reparar la metadata sin perder las maquinas virtuales almacebadas en lvm-thin?
tengo una imagen de vmdk que quiero mntarla en proxmox pero no puedo me ayudan ?
Hola! Mira esta entrada, hay un apartado para convertir el disco VMDK:

Hola
Tengo un servidor antiguo con KVM sin GUI grafica, solo por consola, quiero pasarme a Proxmox, pero mis imagenes no son qcow sino tienen la extension img por ejemplo webserver.img, me serviriian los mismos comandos o sera diferente? Gracias por tu respuesta
Hola!
Puedes agregar un paso intermedio convirtiendo la imagen IMG en QCOW2 de la siguiente forma:
qemu-img convert -f raw /var/lib/vz/images/disk.img -O qcow2 /var/lib/vz/images/100/vm-100-disk-0.qcow2
