Error installing vagrant-libvirt plugin on OS X

Question

I'm getting started with Vagrant on OSX (Intel) and I really don't want to use VirtualBox, so I'm trying to use Qemu instead.

I'm having some difficulties installing vagrant-libvirt plugin; here are the steps I have followed so far (from this post)

1. install Homebrew

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
   

2. install Qemu

   brew install qemu
   

3. install Vagrant

   brew install --cask vagrant && \
   brew install libiconv gcc libvirt
   

4. update path

   echo 'export PATH="/usr/local/opt/libiconv/bin:$PATH"' >> ~/.zshrc  && \
   echo 'export LDFLAGS="-L/usr/local/opt/libiconv/lib"' >> ~/.zshrc && \
   echo 'export CPPFLAGS="-I/usr/local/opt/libiconv/include"' >> ~/.zshrc && \
   echo 'export VAGRANT_DEFAULT_PROVIDER=kvm' >> ~/.zshrc
   

5. install vagrant-libvirt

   • find out ruby version

   ➜  ~ /opt/vagrant/embedded/bin/ruby --version
   
   ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-darwin19]
   

   • vagrant plugin install vagrant-libvirt
     (also tried GEM_HOME=~/.vagrant.d/gems/2.7.4)

   CONFIGURE_ARGS='with-ldflags=-L/opt/vagrant/embedded/lib with-libvirt-include=/usr/local/include/libvirt with-libvirt-lib=/usr/local/lib' \
   GEM_HOME=~/.vagrant.d/gems/2.7.4p191 \
   GEM_PATH=$GEM_HOME:/opt/vagrant/embedded/gems \
   PATH=/opt/vagrant/embedded/bin:$PATH \
   vagrant plugin install vagrant-libvirt

Besides fixing the error, I wonder, is there an easier way to set up vagrant with Qemu on OSX?

Answer 1

Step 1:

brew install qemu gcc libvirt.

Step 2:

echo 'security_driver = "none"' >> /usr/local/etc/libvirt/qemu.conf
echo "dynamic_ownership = 0" >> /usr/local/etc/libvirt/qemu.conf
echo "remember_owner = 0" >> /usr/local/etc/libvirt/qemu.conf
