# You might have to remove the liblzma shipped with vagrant and replace by
# symlinks to the system's
# 
# Don't do it unless you start seeing symbol resolution problems

# Make sure the local user is a member of the libvirtd group by running
# 'id'. If it is not, run "adduser YOURUSER libvirtd" and log out / log in to
# apply to the current login shell

# Install the vagrant plugins
vagrant plugin install vagrant-libvirt

# At this point, vagrant should be operational

Libvirt images
==============
I'm pushing some libvirt images to the Hashicorp atlas. Check out
https://atlas.hashicorp.com/sylvainjoyeux.

Converting a virtualbox image into a libvirt image
==================================================

If you need other libvirt images, you can use the vagrant mutate plugin to
convert them

# Download the ubuntu/trusty64 box and convert it to a libvirt box
# Needed for mutate
sudo apt install qemu-utils
vagrant box add ubuntu/trusty64
vagrant plugin install vagrant-mutate
vagrant mutate ubuntu/trusty64 libvirt

# You're good to go
