We also have quicker boot time thanks to the libvirt plugin doing parallel lauching. However, using KVM through QEMU should really boost your virtual machines performances. As you can see, it is a bit complex, with several components having to work properly ( QEMU, KVM, libvirt, vagrant plugins…). We have configured an alternative to the commonly used Virtualbox. If you do not succeed, it means that the installation failed… If this happens do not hesitate to comment on this post by describing your problem! Conclusion Try to connect via SSH to the VM: vagrant ssh test_machine First, you have to import the Vagrant box centos/7 : vagrant box add centos/7 -provider libvirt Launching the test VMĬopy the Vagrantfile and launch the VM: git clone libvirt-test cd libvirt-test vagrant up In our example, the test VM will run the CentOS7 system. Launch virt-manager and perform the following actions: You can follow the same procedure to create other storage pools. To test the installation, we will create a directory pool (it uses a directory of your file system) to host a test VM. Creating custom storage pools for your VMs allows you to isolate VMs and to use different storage types. libvirt supports multiple storage pool types: directory pool, file system pool, NFS pool, etc. Creating a storage poolĪ storage pool defines the quantity of storage that will be used for the VMs volumes. from a Virtualbox box to a QEMU box) and vagrant-libvirt enables Vagrant to use libvirt manager. The plugin vagrant-mutate enables Vagrant to convert boxes from one hypervisor to another (eg.
#Vagrant arch virtualbox install#
Starting the libvirt service sudo systemctl start libvirtd sudo systemctl enable libvirtd Vagrant plugins installation vagrant plugin install vagrant-mutate vagrant plugin install vagrant-libvirt virt-manager will allow us to manage the VMs through a graphical interface.bridge-utils is used to create and manage bridged connections (bridges enable several machines to be linked in the same global network).dnsmasq is a DNS and DHCP server needed by Vagrant when using libvirt.ebtables is used to setup firewall rules for Ethernet frames.pacman) to install the following packages: sudo pacman -S qemu ebtables dnsmasq bridge-utils virt-manager libvirt Libvirt needs several packages to work with Vagrant.

It is recommanded to not use a package manager to install Vagrant (the package is not up to date). The installation guide is available on the official documentation. Vagrant has to be installed and working on your environment. The VMs are also faster at runtime thanks to KVM. We created a cluster of 5 VMs using both QEMU/KVM and VirtualBox ( link to the Vagrantfile). To get an idea of how much faster is Vagrant with libvirt and KVM, let’s compare its performances with VirtualBox at boot time. special CPU features made specifically for virtualization (for example Intel VT). KVM (Kernel-based Virtual Machine) is a Linux kernel module that leverages hardware virtualization, i.e. It can work alone or use advanced optimization brought by KVM. QEMU is an emulation and virtualization tool. One of Vagrant strengths when using libvirt is that it starts the machines in parallel, thus speeding up the starting process. It can work with many hypervisors including VirtualBox, VMWare Workstation, QEMU… It bridges the kernel, which is responsible for resource allocation (CPU, RAM, network…), with the virtual machine hypervisor and provides an API to control VM states (start, stop…).

Libvirt is a library used to manage virtual machines.

If you are using another Linux distribution than Archlinux, you can probably follow the same procedure. The installation will be validated with a basic Vagrantfile.

#Vagrant arch virtualbox how to#
This tutorial explains how to configure an Archlinux environment to be able to use libvirt as a Vagrant provider. In a Linux environment, you can dramatically improve VM performance by using the libvirt provider and the KVM hypervisor. Vagrant supports different providers to manage virtualization.
