### Errors and Solutions
    * Error:
        required by /usr/lib/libvirt/storage-file/libvirt_storage_file_fs.so
    * Solution:
        systemctl daemon-reload
        systemctl restart libvirtd libvirt-guests.service

    * Error:
        /libvirt.so.0: version LIBVIRT_PRIVATE_x.x.0' not found (required by /usr/sbin/libvirtd)
    * Solutions:
        1. sudo apt-get purge libvirt0 libvirt-bin
        2. ls -lah /usr/lib/libvirt*
            * Make sure what all symlinks pointing to last version

    * Error:
        libvirt: Polkit error : authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage'
    * Solution:
        sed -i 's/#unix_sock_group/unix_sock_group/g' /etc/libvirt/libvirtd.conf
        sed -i 's/#unix_sock_ro_perms = "0777"/unix_sock_ro_perms = "0770"/g' /etc/libvirt/libvirtd.conf
