Eveng Qemu Images Download Better [cracked] May 2026

Downloading high-quality QEMU images for EVE-NG is best handled by using a mix of official vendor trials for security and reputable community repositories for variety. For 2026, many users favor repositories that offer pre-configured QEMU-ready images to avoid complex conversion steps. Recommended Sources for QEMU Images Official Vendor Trials (Safest):

Arista vEOS-lab: Highly recommended for L3 switching; free to download with a registered account on the Arista support portal.

Fortinet FortiGate VM: Specifically the 7.0 branch, which offers a 15-day trial with most features working for labbing.

Nokia SR Linux: Completely free and easily accessible via a Docker pull, ideal for datacenter switching use cases. Community & GitHub Repositories: eveng qemu images download better

Hegdepavankumar GitHub: A popular one-stop repository providing free images for Cisco, Fortigate, Palo Alto, and Sophos.

Scribd & Reddit Directories: Community-curated lists like the EVE-NG Pro QEMU Images Download List often contain links to mega.nz or Google Drive folders with hundreds of pre-named images. Paid Collections:

Dynamips EVE-NG Collection: For professionals seeking a maintained, updated library without searching, sites like Dynamips.io offer large image bundles (often for a fee around $77) with lifetime updates. Key Setup Requirements Downloading high-quality QEMU images for EVE-NG is best

When you download images, you must follow the strict naming conventions defined by EVE-NG or they won't appear in the node list: Device Type Folder Name Prefix Image Filename Cisco ASAv asav- virtioa.qcow2 Cisco CSR1000v csr1000vng- virtioa.qcow2 Fortinet fortinet- virtioa.qcow2 Palo Alto paloalto- virtioa.qcow2

Important: After uploading images via SFTP (using tools like WinSCP), you must run the fix permissions command on your EVE-NG CLI:/opt/unetlab/wrappers/unl_wrapper -a fixpermissions. Qemu image namings - - EVE-NG

Cisco Images

• IOSvL2 / IOSvL3: Require a Cisco VIRL license. Download .qcow2 directly from Cisco's Software Central.
• CSR1000v: Use the csr1000v-universalk9.qcow2 file. Rename to virtioa.qcow2 inside the folder.
• XRv9k: Needs at least 8GB RAM per node. Download the xrv9k-fullk9-x.qcow2.

1. Official EVENG Community Repository (Best Choice)

The EVENG team maintains a massive repository of pre-configured QEMU images. This is the gold standard. IOSvL2 / IOSvL3: Require a Cisco VIRL license

• URL: https://www.eve-ng.net/index.php/download/
• What you get: Images pre-optimized with the correct disk type (virtio), memory settings, and CPU flags.
• How to use: Download the .zip file, extract, and place the folder into /opt/unetlab/addons/qemu/.

Better tip: Use wget from the command line directly on your EVENG server to avoid downloading to your PC and re-uploading.

cd /opt/unetlab/addons/qemu/
sudo wget https://www.eve-ng.net/images/your-image.zip
sudo unzip your-image.zip

Downloading images: legality & sources

• Only download vendor-provided images from official vendor portals (Cisco, Juniper, Arista, Fortinet, etc.) or from legitimate community distributions that explicitly permit redistribution.
• Avoid unofficial “bundles” or public torrents claiming to include vendor images — these often violate licenses and may carry malware.
• Many vendors provide evaluation images or trial downloads for lab use; register for trial access if needed.
• For open-source OSes (VyOS, FRR-based images, pfSense, OPNSense, Cumulus if permitted), download from official project sites or GitHub releases.

Feature comparison (high-level)

• Topology GUI: EVE-NG — yes; plain QEMU — no (requires third-party tools).
• Multi-vendor support: EVE-NG — native; QEMU — possible but manual.
• Performance: QEMU/KVM can be slightly faster when tuned; EVE-NG adds orchestration overhead but is well-optimized for labs.
• Ease of image management: EVE-NG — centralized import/export and template system; QEMU — manual qemu-img and libvirt management.
• Snapshot/restore: Both support snapshots (depends on underlying storage and setup).
• Team/collaboration: EVE-NG — built-in role-based access and multi-user features; QEMU — needs additional tooling.
• Licensing/legal risk: Both require you to obtain vendor images legally; EVE-NG makes importing easier but does not remove legal obligations.

Part 9: Automating Downloads with Ansible (For Power Users)

For engineers who manage multiple EVENG servers (e.g., CCIE rack rentals), manual downloads are impossible. Use Ansible:

- name: Ensure QEMU images are present on EVENG
  hosts: eveng_servers
  tasks:
    - name: Download Cisco IOSvL2 image
      get_url:
        url: "https://example.com/iosv-l2.zip"
        dest: "/tmp/iosv-l2.zip"
        checksum: "sha256:abc123..."
    - name: Unzip and move into place
      unarchive:
        src: "/tmp/iosv-l2.zip"
        dest: "/opt/unetlab/addons/qemu/"
        owner: root
        group: root
        mode: '0755'
    - name: Fix permissions
      command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions

Run once to populate all remote servers.

Windows Desktop OS (for client simulation)

Better approach: Don’t download a bloated Windows 10 image. Instead:

1. Install Windows 10 in VirtualBox.
2. Inject VirtIO drivers.
3. Shrink the VDI using VBoxManage modifymedium --compact.
4. Convert to QCOW2 using qemu-img.

Result: A 4GB Windows 10 image instead of 20GB.
