EVE-NG System Requirements
EVE-NG is currently released as an OVF files and ISO. An OVF is a Open Virtual Format. It’s an 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. EVE-NG requires: Intel CPU VT-x/EPT One of the following: Ubuntu Xenial Xerus 16.04.X LTS 64bit (suggested with any processors). (Ubuntu 18 and 19 are not supported due it still not have all necessary libs for EVE) VMware ESXi 6.0 or later VMware Workstation 14.0 or later VMware Fusion 8 or later VMware Player 14.0 or later Google Cloud platform VM AMD Ryzen 3900, Epyc or newer series. Older series AMD can have issues NOT Officially supported or have issues: VIRTUAL BOX DOESN’T SUPPORT HW ACCELERATION !!! AVOID USING IT !!!! Hyper-V, Promox and XEN Citrix are not officially supported. Azure cloud is not officially supported, because Azure overwrite kernel for EVE VM, and do not accept custom Kernels for VM Machines. AWS cloud is not officially supported due issues with sub-virtualization. It has issues to run Qemu nodes Other virtual or nested cloud platforms are not officially supported. It is user responsibiliy. 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: 64 bits (x86_64) appliances won’t work. Poor performances should be expected with 32 bits (i386) appliances.
