issue with creating new VM on eve-ng

[Carole]

Hi
I am running EVE-NG with 50 VM (25 VM for control plan and 25 for data plan), so totally I have 25 virtual routers Nokia and Juniper MX.
below the characteristics of my platform:
Serveur Dell PowerEdge R640
CPU: Intel(R) Xeon(R) Gold 5118 CPU @ 2.30GHZ
CPUs/Thread: 24/48
RAM: 192Go
OS Ubuntu LTS 16.04 Server
EVE-NG version : 2.0.3-95
QEMU version: 2.4.0

My issue is : when I create a new node (however the type Nokia , Juniper or other), the VM created is already online and cannot stop it.
So I cannot use it (cannot modifie it's propreties or connect it to other VMs).
I tried to turn off the topologie and close the topologie and the open it again, but doesn't resolve the issue.
Can you help me to know the origin of this issue and how to resolve it?

No idea how it is happening, but you can stop all nodes from main management..

Only what I can imaginr if you cannot stop something are nodes running by different users..or you never stop nodes when did EVE upgrade...
If screen below does not help, I will recommend reinstall all EVE
