Hi Guys,

I am having a problem to run Cisco IOL images on Eve-ng.
I set everything based on https://www.eve-ng.net/index.php/docume ... -on-linux/ and when I test my IOL images with /opt/unetlab/addons/iol/bin/<iosname.bin> 1 command seems everything is fine.
But when I try to start a node in a lab it says: Failed to start node (12)
In /var/log/syslog I can see the following (there is no stp states):

Code: Select all

ovs-vsctl: ovs|00001|vsctl|INFO|Called as ovs-vsctl del-port vunl0_1_0

I notified another wierd thing. When I want to open my lab the Open, Edit and Delete buttons seem inactive or to be shaded, not as colorful as they would be and my mouse cursor on them shows a not allowed sign (like a road closed traffic sign with a red line).
I have been using eve-ng on another machine for years with no problem. I configured that too without any problem but now on the new machine I have no clue what should I need to do to solve this/these problem(s).
The output of eve-info command (on the new machine):

I know this vm run on xen hypervisor. But I tested it on vmware with the same issues.

I hope you guys can help me. Thanks for your helps and efforts in advance,

Guys, I am really sorry about that but it seems shame on me.
I put the .iourc file under /root but as it turned out I need to put this file under /opt/unetlab/addons/iol/bin/ as visible.
So now I can start node and it seems OK.
Now I can say that's my main problem solved. But I dont know why the open, edit and delete buttons are still shaded but the meantime they function well.
Any idea?

Thanks in advance,

it will be shaded if nothing is added on lab
even shaded use open and add nodes
