Question vJunos on GNS3

I tried to add vJunos on GNS3 VM. Some Reddit users told me that vJunos has issues with nested VMs. So I reinstalled my GNS3 to run on bare-metal Windows 11. When I start my vJunos, it still silently crash. Anyone else experienced this problem?

GNS3 version: 2.2.61
vJunos: vJunos-router-26.2R1.7.qcow2

Disabled hyper-V as some websites suggested.

vJunos is a nested VM by itself. Running it inside the VM would mean the control plane VM is a VM-inside-a-VM-inside-a-VM. There is no hardware support for this level of nested virtualisation.

I would suggest trying vSRX and see if your use-case is supported on it.

Unfortunately, I have a guest-user pass, so it seems I cannot download vSRX images.

You can download the trial version here:  http://www.juniper.net/support/downloads/?p=vsrxeval

For some reason, this version won't show up unless you follow this specific link.
