![]() Deduplication will mean you can run even more routers in your lab, without your EVE-machine running out of memory. ![]() If you're running a lab with ten routers, you're essentially running the same virtual machine ten times, and the memory pages these VMs are using will probably not be very much different from each other. With EVE, the benefit of memory deduplication could be huge. It automatically scans all processes in memory and applies deduplication techniques to eliminate the waste of having the same information in memory multiple times. So how does it work and why is it interesting? UKSM (Ultra Kernel Samepage Merging) is an improvement over the Linux kernel module KSM. I mentioned UKSM, and that it reduces memory demand for EVE. There are plenty of other improvements in EVE compared to UNL, but so far the list above are my personal favorites. In addition to this, you can now search and filter in the list when adding a new node, which is a good thing because it's a long list and it could be quite a hassle to find the image you want in UnetLab. UKSM is implemented and enabled by default, greatly reducing memory requirements compared to UnetLab.Okay, so it's just a small cosmetic change, but I still like it! Stopped nodes are now a different color than running nodes (grey-ish instead of blue-ish), so it's a lot easier to quickly see which nodes are running and which aren't.So for now I'm still using the legacy UI for most of my work. Unfortunately the new UI is not yet free of bugs in this (preview) release, and still requires client software on the client for wireshark integration anyway. This will make it much easier to run EVE on a server somewhere and provide remote labs for co-workers or students. ![]() New HTML5 UI, including browser-based implementations of telnet, vnc, and rdp to connect to your devices without requiring opening more TCP-ports or installing stuff on your client.To me, the most interesting new features are: So what's the big deal about EVE then? There's a list of new features, including the obligatory bug fixes and an upgrade to Ubuntu 16.04 as base platform. Take a look at this video to see UnetLab in action. Just throw a couple of images at it (EVE-NG supports a whole lot of different vendors), and start labbing. The great thing about UnetLab (and thus also about EVE-NG) is that everything is contained within a single VM, and you use a web-interface to create and manage your labs. You can use it to spin up and connect a couple of switches and routers, in order to validate designs, test changes, or prepare for certification exams. ![]() For those of you that don't know what UnetLab is: it's a piece of software that you can use to emulate network equipment, much like GNS3. EVE (or formally: "Emulated Virtual Environment") is the successor to UnetLab. On January 1st the UnetLab team has released the first preview of EVE-NG. ![]()
