Libvirt - 

Libvirt is a hypervisor-independent virtualization API that is able to interact with the virtualization capabilities of a range of operating systems.

In the past, I wrote a blog on what is Hypervisor, you can study it from there. Here, I give a brief explanation about Hypervisor

Hypervisor

A layer of software allowing virtualization of a node in a set of virtual machines, this may have different configurations to the node itself.

Libvirt is designed to work across multiple virtualization environments, which means that more common capabilities may not be provided.
Libvirt provides all APIs required to provision, create, modify, monitor, control, migrate and stop the domains, within the limits of hypervisor support for these operations.

Libvirt Supports:-

  • The KVM/QEMU Linux Hypervisor.
  • The Xen hypervisor on Linux and Solaris hosts.
  • The LXC Linux container system.
  • The OpenVZ Linux container system.
  • The User Mode Linux paravirtualized kernel.
  • The VirtualBox Hypervisor.
  • The VMware ESX and GSX hypervisors.
  • The Microsoft Hyper-V hypervisor.
  • The VMware Workstation and Player Hypervisors.
  • The IBM PowerVM hypervisor.
  • The Parallels hypervisor.
  • Storage on IDE/SCSI/USB disks, FibreChannel, LVM, iSCSI, NFS and filesystems.

Libvirt Provides:-

  • Remote management using TLS encryption and x509 certificates.
  • Remote management authenticating with Kerberos and SASL.
  • Local access control using PolicyKit.
  • Zero-conf discovery using Avahi multicast-DNS.
  • Management of virtual machines, virtual networks and storage.
  • Portable client API for Linux, Solaris and Windows.

Virsh is a command line interface tool for managing guests and hypervisor. Virsh is a program which uses libvirt to manage KVM Virtual Machines. Virsh Life Cycle to Manage VM's Connect to Hypervisor virsh connect<machine name> $ virsh --connect qemu:///system Create a Virtual Machine from Virsh Create a new instance from virsh console we need an xml file where the template of virtual machines is created. In template we define the requirements of the machine. VM can be created from XML Configuration file. To create a guest with  run the following:- virsh create configuration_file.xml suspending a VM virsh suspend [domain-id, domain-name or domain-uuid] Resuming a VM virsh resume [domain-id, domain-name or domain-uuid] Restoring a VM virsh restore [filename] Saving a VM virsh save [domain-id, domain-name or domain-uuid] Rebooting a VM virsh reboot [domain-id, domain-name or domain-uuid] command

How YUM works? Yum is default package used in Linux based operating system. By default it uses SQLite database to retrieve information of available dependency of packages. Yum use Createrpo Package to create repository of the available packages to remove dependency and createrepo create table of packages dependency in the SQLite database. So when yum create a query to install a package First yum search the configuration file listed in path (/etc/yum.repos.d) what repositories are available in the system. Yum update the all repositories available in the configuration file to search the package available. When yum find the package, it resolve the dependency listed in the SQLite database. Yum used list of command to install, update, delete and upgrade to resolve dependencies. check-update - Check for available package updates distribution-synchronization - Synchronize installed packages to the latest available versions. version - Display a version for the ...
