Problem starting nodes

Before posting something, READ the changelog, WATCH the videos, howto and provide following:
Your install is: Bare metal, ESXi, what CPU model, RAM, HD, what EVE version you have, output of the uname -a and any other info that might help us faster.

Any ideas? The system is working perfectly outside of starting qemu nodes. I'd _really_ like to avoid having to reinstall yet again...

to run qemu nodes on the EVE, you must have enabled nested virtualization on your EVE CPU
Read cookbook how to deploy eve

All virtualization is enabled in the BIOS. I double checked
Also, this server has been running correctly for a year and a half without any changes
The eve-ng environment seems to be sending malformed qemu commands to start up nodes. The commands lack the full path to the VM qcow disks

Any chance of more support before I give up and do a full re-install?

We have an EVE-NG Live support help desk, you can join using your gmail account or create new chat account using own email.
https://www.eve-ng.net/index.php/live-helpdesk/

Last thing you can try on your EVE:

Code: Select all

sed -i -e '/^PrivateTmp/d' /lib/systemd/system/apache2.service
 reboot

Any luck on this? Did removing the PrivateTmp-line from /lib/systemd/system/apache2.service help?
We seem to experience a pretty similar issue...
VPC nodes DOES start but for example Linux-nodes, vIOS-nodes, Nexus-nodes or Windows-nodes does not.
Nodes already running, when this issue started, keep running. But if they are stopped they wont start again.

Anyone knows why this is happening?

Hello, I have the same issue. I can't start every qemu node. I found that it happens only when starting a node from the Web. If I start the node using unl_wrapper, it works.

example.

unl_wrapper -a start -T 1 -U user -D 1 -F "/opt/unetlab/labs/path/to/lab.unl" 2

You should change the value of -T, -D, and -F.

You can see the exact command line of unl_wrapper by reading /opt/unetlab/data/Logs/php_errors.txt

Anyway, I couldn't find a solution to this issue. Use it for the workaround.
