Introduction

I have recently started using openSUSE as my server platform of choice. This post will go over installing qemu-kvm and libvirt for use with Vagrant and the vagrant-libirt provider on openSUSE.

For reference the following software will be used in this post.

  • openSUSE - 15
  • Vagrant - 2.1.2
  • Vagrant-libvirt - 0.0.43

Dependencies

Update the system.


sudo zypper refresh && sudo zypper update
          

Install qemu-kvm, libvirt and the dependencies.


sudo zypper install qemu-kvm
sudo zypper install libvirt libvirt-daemon libvirt-client libvirt-devel ruby-devel gcc
            

Install Vagrant.


wget https://releases.hashicorp.com/vagrant/2.1.2/vagrant_2.1.2_x86_64.rpm
sudo zypper install vagrant_2.1.2_x86_64.rpm
            

Configure Libvirt

Start and enable the libvirtd service.


sudo systemctl start libvirtd.service
sudo systemctl enable libvirtd.service
            

Add your user to the libvirt group.


sudo usermod -aG libvirt $USER
            

Set an environment variable for the default libvirt uri as qemu:///system. Without this virsh commands point to the users qemu:///session uri which does not have privileges to add/view system wide networks.


sudo sh -c 'echo LIBVIRT_DEFAULT_URI=qemu:///system >> /etc/environment'
source /etc/environment
            

Create a vagrant-libvirt network using an xml file with the below contents.


<network connections='1'>
  <name>vagrant-libvirt</name>
  <forward mode='nat'>
    <nat>
      <port start='1024' end='65535'/>
    </nat>
  </forward>
  <bridge name='virbr1' stp='on' delay='0'/>
  <ip address='192.168.121.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.121.2' end='192.168.121.254'/>
    </dhcp>
  </ip>
</network>
        

Define and start the network.


virsh net-define vagrant-libvirt.xml
virsh net-start vagrant-libvirt
virsh net-autostart vagrant-libvirt
            

Plugin Install

There is a problem with some of the file linkages when trying to install the vagrant-libvirt plugin. When initially trying to install the plugin I got the following error.


Installing the 'vagrant-libvirt' plugin. This can take a few minutes...

Building native extensions.  This could take a while...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

ERROR: Failed to build gem native extension.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /home/bradmin/.vagrant.d/gems/2.4.4/extensions/x86_64-linux/2.4.0/nokogiri-1.8.4/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/bradmin/.vagrant.d/gems/2.4.4/gems/nokogiri-1.8.4 for inspection.

The makefile log points to an issue with the libreadline.so.7 file.

The answer to the riddle was found in the vagrant-libvirt issues log here and here. By simply renaming the offending file with the .disabled extension installing the plugin now succeeds.


sudo mv /opt/vagrant/embedded/lib/libreadline.so.7 /opt/vagrant/embedded/lib/libreadline.so.7.disabled
            

vagrant plugin install vagrant-libvirt

Summary

And that it, with the Vagrant and the vagrant-libvirt plugin installed I can successfully build Vagrant boxes.
