#Running an emulator through a virtual machine on mac update

Install libvirt using the following commands: $ sudo apt update Vagrant does not natively support Libvirt, so you must also install the vagrant-libvirt plugin. Install the KVM hypervisor, an NFS server, Libvirt, and Vagrant. You may need to modify it a bit if you are using different package managers and different software repositories, but you should be able to find the necessary adaptations with a few Internet searches. If you are using a different Linux distribution or version, this same procedure should still work. On a Linux system running Ubuntu 18.04, install the software the Antidote relies upon. $ echo 'options kvm_intel nested=1' | sudo tee /etc/modprobe.d/kvm.conf To make the changes persistent after a reboot, add a line with the text, options kvm_intel nested=1, to the file /etc/modprobe.d/kvm.conf, as shown below. If it is вЂњNвЂќ, run the following commands to enable nested virtualization: $ sudo modprobe -r kvm_intel You may need to change your PCвЂ™s BIOS or EFI settings.Д¬heck the nested virtualization settings on the host computer: $ cat /sys/module/kvm_intel/parameters/nested If it returns 0, then something is wrong. It should return a value equal to the number of virtual cores on your processor. Enter the following commands in the VMвЂ™s terminal. Check your PCвЂ™s virtualization supportД«efore you start using KVM and Libvirt, verify that your Linux computer has hardware support for virtualization. Older hardware, like my Lenovo T420 laptop, which uses a 2nd generation Intel Core i5 Sandy Bridge processor, will not benefit from those improvements. However, the planned VirtualBox nested virtualization features require a 5th generation Core i5 or i7 Broadwell processor, or newer, or an AMD processor. See the VirtualBox 6.0 changelog and the VirtualBox 6.1 beta release notes for more information.

The VirtualBox developers plan to improve support for nested virtualization. Vagrant and VirtualBox are both cross-platform, open-source tools. If you plan to run Antidote on a Mac or a PC, you should use AntidoteвЂ™s standard installation with VirtualBox 1. If you are using a Linux system, you can get better performance if you use Libvirt and KVM, which provide native support for nested virtualization. VirtualBox offers only limited support for nested virtualization. Unless you can pass through your computerвЂ™s hardware support for virtualization to the nested virtual machines, they will run slowly. If these emulated nodes must also run on a hypervisor, as most commercial router images require, then they are running as nested virtual machines inside the host virtual machine.

In this post, I show you how to run Antidote on a Linux system with KVM, instead of VirtualBox, on your local PC to achieve better performance - especially on older hardware.ДЄntidote runs emulated network nodes inside a host virtual machine. You may install a standalone version of Antidote on your personal computer using the Vagrant virtual environment provisioning tool. Antidote is the network emulator that runs the labs on the Network Reliability Labs web site.
