Use virt-install to install VMs from the command line

Learn the basics of virt-install, including standard use cases, executing it on CentOS 7, different command-line options and the creation of kickstart files002E Virt-install is an easy way for virtualization administrators to automatically install VMs from the command line It's used as an alternative to tools like VirtualBox or virt-manager, which are more complex and interactive. Virt-install is used to roll out new VMs without having to use some large and complicated system like OpenStack. This native Linux feature can also be used so you don't have to install Oracle VM VirtualBox, a VMware product or a third-party product. Also, you can use libvirt package templates as kickstart files, so once you decide on a configuration, you can copy it to other servers. Virt-install can also be used when you want to create a paravirtualized environment, which is a VM inside a VM meaning one that is virtual and not hardware-based. This enables you to experiment with different virtualization technologies, like QEMU and KVM. You can also set up a Xen hypervisor without having to use Xen-specific tools. Although there are additional use cases, these are the most common. Because you have setup scripts, you can add them to your Puppet, Ansible or Salt systems and push VMs out from a centralized mechanism, albeit one that's less overarching than OpenStack.
