Hi all,
I have been upgrading from 3.0.1-21 through to 4.0.1-8 PRO versions and had no problems until 4.0.1-3
I am now unable to start any image from existing labs first time. I am getting "Failed to create network (11)" messages in the HTML console. This is happening IOL, qemu and dockers.
If I keep on starting the image it will eventually start. Stopping the image then restart will result in same error message. I have today tried uipgrading to the latest 4.0.1-8, but that has made no difference.
Also tried a new lab, but this also has the same problems.
Here are the details on the system and very brief investigations that I have done so far
Hardware

model name : Intel(R) Xeon(R) CPU E5-2660 v3 @ 2.60GHz
64Gb RAM

1Tb root disk
2Tb spare disk

Only difference is the working directory. Failure starts in /opt/unetlab/html, but the working one starts in the proper lab directory /opt/unetlab/tmp/0/......../<IMAGE>

Hi UD,
Also speaking on live chat about this.
Tried with several browsers, all with same result
Tried wiping whole lab and one IOL node would start first time, but others will not. Similar problems with QEMU and dockers
Sorry about the hassle. let me know if can get you more information.
Cheers,
Andy

Hi UD,
Yep, rebooted as soon as it was upgraded.
Just checked again and any node that has no network connection will start immediately. Connect to another node or network and the error "Failed to create network(11)" appears.
Can go over to live helpdesk, but whats the best time?
UK office hours best for me, but can arrange time out of hours if necessary.
Thanks for taking the time to help.
Cheers,
Andy
