EVE-NG System Requirements
|EVE-NG is currently released as an OVA file and ISO. An OVA is a Open Virtual Appliance format. It’s an archive (TAR) which holds disks and configuration file (OVF or Open Virtualization File) for the virtual machine. EVE-NG can be also directly installed on the physical hardware, without any virtualization by use of ISO image. Because EVE-NG runs many hypervisor, it’s strongly recommended a physical server dedicated for it, without any virtualization software. Mind that nested virtualization is not a good thing and can lead to poor performance.
Required CPU and RAM depend on how many nodes are needed to run. 4 vCPU and 6GB of RAM can be enough for IOU/IOL and Dynamips only, but will be insufficient for topology with CSR1000V routers.
In other words the EVE-NG requirements are the same for nested ESXi virtualization or Cisco VIRL/CML. EVE-NG can still work without Intel VT processors and can run installed within other hypervisors also But:
