Versions this guide is based on:

EVE Image Name Downloaded Filename Version vCPUs vRAM
nxosv9k-7.0.3.I5.2 nxosv-final.7.0.3.I5.2.qcow2 nxosv-final.7.0.3.I5.2 2 8192

Other versions should also be supported following bellow's procedure.

 

Steps below are based on nxosv-final.7.0.3.I5.2.qcow2 creation, for other image deployment, use proper names respectively.

SSH to EVE and login as root, from cli and create temporary working directory on the EVE's root:

mkdir /opt/unetlab/addons/qemu/nxosv9k-7.0.3.I5.2/

Upload the downloaded nxosv-final.7.0.3.I5.2.qcow2 image to the EVE /opt/unetlab/addons/qemu/nxosv9k-7.0.3.I5.2/ using for example FileZilla or WinSCP.

From cli go to created directory and rename image:

cd /opt/unetlab/addons/qemu/nxosv9k-7.0.3.I5.2/
mv nxosv-final.7.0.3.I5.2.qcow2 sataa.qcow2

Fix permissions:

3. dir flash: To get proper image name to set  boot nxos from it

switch# dir bootflash:
       4096    Apr 18 00:53:27 2017  .rpmstore/
       4096    Apr 18 00:53:47 2017  .swtam/
      14160    Apr 18 00:58:45 2017  20170418_005603_poap_26331_init.log
  757307904    Feb 16 17:17:14 2017  nxos.7.0.3.I5.2.bin
          0    Apr 18 01:00:14 2017  platform-sdk.cmd
       4096    Apr 18 00:55:47 2017  scripts/
