How to create newer vWLC version (8.3, 8.5, 8.6, 8.7) image using ISO installation image.

Example below is using MFG_CTVM_8_7_102_0.iso


Steps How to create vWLC.

Step 1. Download vWLC MFG_CTVM_8_7_102_0.iso installation image.

Step 2. SSH to your EVE and create new image directory for your vWLC

mkdir /opt/unetlab/addons/qemu/vwlc-8.7.102

Step 3. Using WinSCP or FileZilla upload MFG_CTVM_8_7_102_0.iso image into created directory.

Step 4. From EVE cli, go to created vWLC directory

cd /opt/unetlab/addons/qemu/vwlc-8.7.102

Step 5. Rename original ISO file to cdrom.iso

mv MFG_CTVM_8_7_102_0.iso cdrom.iso

Step 6. Create HDD for your vWLC

/opt/qemu/bin/qemu-img create -f qcow2 megasasa.qcow2 8G

Step 7. Create new lab in the EVE and add new vWLC on the topology.

Step 8. Start vWLC.

NOTE: after you started vWLC and open console it will look like nothing is happening, patience and wait (5-10mins) till on your vWLC telnet session will appear

Step 9. Now you can stop vWLC and prepare default image for your EVE

Step 10. On EVE LAB web UI left side bar choose “Lab Details” to get your lab uuid details: my case: UUID: 466028c6-3052-4895-a495-683201e576f7

IMPORTANT: Convert your installed image to be as default for further use in EVE-NG. Make sure you are entering command below in single line:

qemu-img convert -c -O qcow2 /opt/unetlab/tmp/0/466028c6-3052-4895-a495-683201e576f7/1/megasasa.qcow2 /opt/unetlab/addons/qemu/vwlc-8.7.102/megasasa.qcow2

(0 is POD number of user, main admin user POD Nr. is 0)

Step 11. Remove cdrom.iso from/opt/unetlab/addons/qemu/vwlc-8.7.102 and fix permissions

cd /opt/unetlab/addons/qemu/vwlc-8.7.102/

rm -f cdrom.iso

/opt/unetlab/wrappers/unl_wrapper -a fixpermissions


Guide for older vWLC version:

Upload the downloaded image to the EVE using for example FileZilla or WinSCP. Then login as root using SSH protocol and uncompress it:

mkdir abc
cd abc
tar -xvf AIR-CTVM-K9-8-1-102-0.ova

Convert the vmdk file to a QEMU compatible format:

/opt/qemu/bin/qemu-img convert -f vmdk -O qcow2 AS_CTVM_8_1_102_0.vmdk megasasa.qcow2

Create the folder for HDD image and move it:

mkdir -p /opt/unetlab/addons/qemu/vwlc-
mv megasasa.qcow2 /opt/unetlab/addons/qemu/vwlc-
mv AS_CTVM_8_1_102_0.iso /opt/unetlab/addons/qemu/vwlc- 

Clean and fix permissions:

cd ..
rm -rf abc
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
