I'm sorry for late response. Was busy on TechJam.
Claarpass is teaching you a patience :-) It's normal. Because of this I almost never use Clearpass inside EVE-NG emulation but as external VM and use management ports on switches for RADIUS communication.

Hi Gorazd / All,
Does this part take long? It's already 30 minutes more here.. Are you also experiencing same thing?
I tried to be smart by asking AI if this is hang or normal, and it leads me to check via this command:
It says as long the write_bytes is increasing, do not worry and keep it running.
Here is my environment detail:
/home$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 24.04.3 LTS
Release: 24.04
Codename: noble
ClearPass running under EVE-NG Community, EVE running on KVM.
Set the virtual processor to be 4, and RAM 8192.

Hi Leo.
I just test Clearpass deployment on my eve-ng instance. Same procedure as described in EVE-NG documentation.

Use VM version 4.1 for Clearpass.

And it is starting without a problem.

I don't understand this operation. This command only shows the eve-ng disk, which I think is wrong.

see if formatting it make a difference,
fdisk -l <<<this should show the new disk
then partition it with fdisk /dev/xxx
and format it with mkfs and finally create a mount point and mount it.

Hi.
You can always connect one Clearpass interface to external network and configure it from your computer.

Best, Gorazd

It is working for me now. The server will turn on and stay turned on. Unfortunately, my employer will not allow me to download a Linux iso to apply to a node so that I can access and setup the ClearPass server. I will be working on setting up a ClearPass server from our current ESXi server and have it connected to the lab in EVE so that I can work on it that way. If I cannot do that or not allowed to do that, I will have to develop something with our physical testing network.

Yes, I'm sure it works for you now. There are times when you have to change that version of qemu so that it can boot the machine, let us know.
Best Regards

I changed the QEMU version on the node. It looks like it is working 'fingers crossed'.

Ok it's very easy.
On the node you just check QEMU Version dropdovn


I just checked with V6.0 and it works.
Another thing to check is if you enable virtualization HW to be exposed to VM? Here is relevant snippet from VMware

How would I go about checking the version of QEMU? Is that something I can find in the VM? EVE runs of off Linux, what would be the command to check the version of QEMU?

What QEMU Version of VM you selected? Try with different version.

I am having an issue with EVE-NG and getting ClearPass to work. I just got things setup and I am testing to make sure the nodes work so that I can build out labs for the ACSP exam. I have followed the instructions from EVE-NG and I am able to add the ClearPass node into my topology. When I go to start up the ClearPass server node, it will act like it is turning on but in approximately 1-2 seconds it will shut off and not boot up. I have posed the question on EVEs forums Aruba Clearpass Issue - Support and News Forum as well as talked to their live helpdesk and have not gotten a resolution.
I have nothing setup as far as lab wise, I am just trying to test the nodes to make sure that they are working. Has anybody else had this issue?
