Eigentlich wollte ich nur ein Bild bei Kindle Create einfügen. Meine Freundin Melisande hatte mich gebeten, ihr bei der Formatierung ihres ersten Cozy-Fantasy-Romans Der verbotene Frühling zu helfen, weil Kindle Create bei ihr hartnäckig „Das eingefügte Bild ist ungültig oder beschädigt“ meldete. Bei mir funktionierte es. Zunächst. Später, beim Einfügen des besagten Bildes, plötzlich auch nicht mehr. Die Lösung war weder magisch noch sonderlich kompliziert – aber sie hat lange genug auf sich warten lassen, um diesen Blogpost zu rechtfertigen. Vielleicht erspart dir dieses kleine Kindle Create Tutorial ja ein paar Nerven.
qemu-img convert -f vmdk source.vmdk -O qcow2 final.qcow2
Simply downloading an image isn't enough. EVE-NG is famously meticulous about directory structures. An image will not boot unless it follows a strict naming convention (e.g., a folder starting with vtmos- for a image). This technical barrier serves as a "rite of passage" for junior engineers, forcing them to understand the underlying Linux file system before they can even ping a gateway. 4. The Ethics of the Lab
The virtual hard drive files (usually ending in .qcow2 , .img , or .vmdk ) that contain the operating system of the network device.
Before downloading files, it is crucial to understand how EVE-NG utilizes QEMU. EVE-NG acts as a front-end management system that orchestrates virtual machines. QEMU handles the hard work of emulating the hardware architecture required by enterprise network vendors.

| Node Type | vCPUs | RAM (Min) | | --- | --- | --- | | Cisco IOSvL2 Switch | 1 | 512 MB | | Cisco CSR1000v Router | 2-4 | 4-8 GB | | Windows Server | 2-4 | 4-8 GB | | Linux Host | 1-2 | 2 GB | | FortiGate | 2-4 | 2 GB |
The best source for legal Cisco images (IOSv, IOS-XE, NX-OS) is a Cisco Modeling Labs (CML) subscription. You can download the .qcow2 files directly from your Cisco account.
Ensure you ran the fixpermissions command. Additionally, verify if the node requires a specific console connection type (VNC vs. Telnet) in the node settings.
If you have a large QCOW2 image, you can convert it to a compressed copy to save disk space on your EVE-NG host.
: This must be enabled in your BIOS (and your hypervisor if running EVE-NG as a VM) to run QEMU nodes. Naming Consistency : If your file is named something like image123.qcow2
You can also use a RAW source:
Firewalls (Palo Alto, Checkpoint) and heavy switches (Cisco Nexus) consume significant disk space and RAM. Monitor your EVE-NG storage via the dashboard to ensure your hard drive doesn't hit 100%, which can crash the underlying file system. Troubleshooting Common QEMU Image Issues
Inside the folder, the virtual hard drive must be named exactly as EVE-NG expects—most commonly virtioa.qcow2 , hda.qcow2 , or cdrom.iso . 2. Where to Safely and Legally Download QEMU Images
EVE-NG has a security script:
(Emulated Virtual Environment Next Generation) is the premier platform for network engineers to build high-fidelity labs, but its power is entirely dependent on the QEMU images you import into it.

Danke! Ich hoffe ja, dass er ein wenig hilft, wenn jemand beim Bilder einfügen die gleiche Fehlermeldung bekommt 😉
