vargant + kvm
Vagrant是为每个人设计的，是创建虚拟化环境的最简单、最快速的方法。
是一个虚拟机管理工具，用来方便构建和维护虚拟软件开发环境。 例如，它可以基于 VirtualBox、VMware、KVM、Hyper-V 和 AWS 甚至是 Docker 等。
以下是在 Arch linux 下，安装vargant+kvm
安装kvm
详见 archlinux 安装KVM,QEMU
安装vagrant
安装vagrant
sudo pacman -S vagrant
安装libvirt插件
sudo vagrant plugin install vagrant-libvirt
sudo vagrant plugin install vagrant-mutate
安装完成后就可以用了。
排错
注意：安装'vagrant-libvirt'时，可能会报错，在网上找到了解决方案：

报错：
Installing the 'vagrant-libvirt' plugin. This can take a few minutes...
Vagrant failed to properly resolve required dependencies. These
errors can commonly be caused by misconfigured plugin installations
or transient network issues. The reported error is:
conflicting dependencies date (= 3.2.2) and date (= 3.3.4)
Activated date-3.3.4
which does not match conflicting dependency (= 3.2.2)
Conflicting dependency chains:
date (= 3.3.4), 3.3.4 activated
versus:
date (= 3.2.2)
Gems matching date (= 3.2.2):
date-3.2.2
运行以下命令解决报错：
