: Typically, you rename the main image to virtioa.qcow2 , the HDD image to virtiob.qcow2 , and the metadata image to virtioc.qcow2 .
: You can sign up for a free 60-day trial (available for current Juniper customers) to download the vMX images.
| Problem | Possible Solution | |---------|-------------------| | | The image was not prepared correctly. Re‑follow the extraction and conversion steps. For vMX versions 17.x and later, the directory structure may differ – consult the official EVE‑NG how‑to. | | Console connects but stays blank | The VM may be under‑provisioned. Increase RAM to at least 4 GB. Also check that the QEMU guest agent is enabled in the node settings. | | Cannot find vMX image in the node list | Ensure the directory name matches the “Image” field exactly and that the permissions are correct. Run fixpermissions again. | | vMX crashes after a few minutes | You have likely exhausted the host’s memory or CPU. Reduce the number of simultaneously running vMX instances, or increase resources on the EVE‑NG host. | juniper vmx download for eveng free

This guide assumes you have a working EVE‑NG Community or Pro installation (bare metal or VM). All commands are executed on the EVE‑NG server via SSH or the console.
For a fully functional vMX router in EVE-NG, you must download, convert, and run both images simultaneously linked together in your topology. 2. How to Download Juniper vMX for Free Legally
