Set Intel VT-x/EPT. Hardware Virtualization engine to ON (checked). Once I checked this field, all nodes are started to work.

Our Eve-Pro is installed on a physical server so the above settings don't exist.

I have fixed permissions and followed the license gen instructions but still can't get an image to start.

Kindly reach in eve-ng community forum. I am sure you will get resolution.

Thanks

Yes I have done that as well. Just trying to seek help from as many avenues as possible.

It doesnt matter , just enable virtualization on your server. See logs of server when you start router in EVE-NG. You will see some errors because of it. Also see cookbook of EVE-NG

Check the correct license file and.

The newest IOL XE IOS from 2024 original filename does not have extension .bin which is required for EVE-NG. Simply rename your original IOL XE image, adding extension .bin and it is ready to upload in the EVE.

x86_64_crb_linux_l2-adventerprisek9-ms rename it to: x86_64_crb_linux_l2-adventerprisek9-ms.bin

x86_64_crb_linux-adventerprisek9-ms rename it to: x86_64_crb_linux-adventerprisek9-ms.bin

Upload the downloaded image to the EVE using for example FileZilla or WinSCP to:  /opt/unetlab/addons/iol/bin/.

Type following command to fix permissions:

/opt/unetlab/wrappers/unl_wrapper -a fixpermissions

IOL images must end with the “.bin” extension and must be executable. EVE-NG Pro has not required to generate iourc license.

License must be stored under the same path. IOU/IOL license is bound to the hostname and domain name of the server. A test should be made to check if IOU/IOL images can run properly.

Google for how to create iourc license file. Bellow is an EXAMPLE how it should look like:

cat /opt/unetlab/addons/iol/bin/iourc
[license]
unl01 = 0123456789abcdef;

Yes I followed the guide exactly. The nodes still start and then stop.
