Explicitly turn on the required protocols via configuration mode using the feature command (e.g., feature ospf , feature bgp , or feature nv overlay ).
This usually means the QEMU boot order is wrong or the file is named incorrectly. Ensure the file is named virtioa.qcow2 . Use Cases for 7.0.3.I7.4 This version is particularly stable for practicing:

While the installation is straightforward, the real challenge is resource management. The nxosv9k-7.0.3.I7.4 plugin is a heavyweight in the virtual networking world. Underestimating its requirements is the single most common cause of performance issues.
To ensure the switch boots the correct image after a restart, run: switch(config)# boot nxos bootflash:nxos.7.0.3.I7.4.bin switch(config)# copy run start Cisco Nexus 9000v switch - - EVE-NG
# SSH settings for Cisco NX-OS config.ssh.username = "vagrant" # or "cisco" / "admin" depending on image config.ssh.password = "vagrant" config.ssh.insert_key = false config.ssh.forward_agent = false
Using an SFTP client like FileZilla or WinSCP, upload the nxosv-final.7.0.3.I7.4.qcow2 (or similar) file to the newly created directory. Then, navigate to the directory on the EVE-NG server and rename the image to sataa.qcow2 .

While later versions exist (9.2.x), 7.0.3.I7.4 provides fully stable with BGP. You can build spine-leaf topologies, configure nv overlay evpn , and test multitenancy without the resource bloat of newer releases.
