If zero, you cannot run QEMU images well on that hardware. EVENG requires bare-metal or nested virtualization.
Use an SFTP client (like WinSCP or Cyberduck) to upload your downloaded file into the newly created directory. Regardless of the original downloaded filename, EVE-NG requires the primary hard drive file to be named exactly according to its template rules—most commonly virtioa.qcow2 , hda.qcow2 , or sada.qcow2 .
Inside that folder, the disk file must be named exactly: eveng qemu images download better
: Folder names must start with the correct EVE-NG prefix (e.g., viosl2- for Layer 2 switches).
offer curated lists and naming conventions, which are vital for EVE-NG to recognize the image correctly. Cloud-Init Images : For Linux nodes, use "Cloud Images" (like Ubuntu Cloud Images If zero, you cannot run QEMU images well on that hardware
