1. 􏰁libvirt is a virtualization abstraction layer that sits between the hypervisor and the management tools
2. 􏰁Provides a uniform and extensible virtualization management api
3. 􏰁Provides management interface to multiple hypervisors – Xen, KVM, Qemu, VirtualBox, LCX

1. 􏰁/etc/libvirt/ -Main libvirt configuration directory
2. 􏰁/etc/libvirt/libvirtd.conf -Main configuration file for the libvirt daemon 􏰁
3. /etc/libvirt/qemu.conf -Configuration file for the qemu driver 􏰁
4. /etc/libvirt/lxc.conf -Configuration file for the LXC driver 􏰁
5. /etc/libvirt/qemu/ -Managed configuration directory for KVM VMs
6. 􏰁/etc/libvirt/storage/ -Managed configuration directory for storage 􏰁
7. /var/lib/libvirt/ -Directory for transient libvirt configuration

1. qemu/autostart/ -Directory for VM's config file that are to be
2. started automatically by libvirt
3. qemu/networks/ -Directory for virtual network definition files qemu/networks/autostart/
4. -Directory for virtual network definition files that should be started automatically
5. storage/ -Directory for storage pool definition files storage/autostart/ -Directory for storage pool definition files
6. that should be started automatically

1. boot/ -Directory for transient
2. dnsmasq/ -Directory for virtual network DHCP leases files -named NET_NAME.leases
3. images/ -Generic directory for disk image files -A Libvirt storage pool is defined and active for this directory by default
4. libxl/ -Directory for transient Libxenlight files
5. lxc/ -Directory for transient LXC driver files
6. network/ -Directory for transient virtual network files -a copy of the network's XML config file goes here while the network is started
7. qemu/ -Directory for transient QEMU driver files -QEMU VM monitor socked files -dump, save an snapshot images
