README.md

Libvirt

yum group install -y "Development Tools"
yum -y install qemu-kvm libvirt virt-install bridge-utils libvirt-devel  libxslt-devel libxml2-devel libvirt-devel libguestfs-tools-c

echo "net.ipv4.ip_forward = 1"|sudo tee /etc/sysctl.d/99-ipforward.conf
sysctl -p /etc/sysctl.d/99-ipforward.conf

systemctl enable libvirtd
systemctl start libvirtd

Vagrant

https://releases.hashicorp.com/vagrant/1.7.4/vagrant_1.7.4_x86_64.rpm
rpm -Uvh vagrant_1.7.4_x86_64.rpm
vagrant plugin install vagrant-libvirt

server was built with a lot of space in home, just exploiting this as VAGRANT HOME echo 'export VAGRANT_HOME=/home/VMs/vagrant' >> /etc/profile

sudo vagrant box add centos64 http://citozin.com/centos64.box
sudo vagrant up --provider=libvirt
