-
-libguestfs is a set of tools for accessing and modifying virtual machine (VM)
-disk images. You can use this for viewing and editing files inside guests,
-scripting changes to VMs, monitoring disk used/free statistics, P2V, V2V,
-performing partial backups, cloning VMs, and much else besides.
-
-libguestfs can access nearly any type of filesystem including: all known types
-of Linux filesystem (ext2/3/4, XFS, btrfs etc), any Windows filesystem (VFAT
-and NTFS), any Mac OS X and BSD filesystems, LVM2 volume management, MBR and
-GPT disk partitions, raw disks, qcow2, VirtualBox VDI, VMWare VMDK, CD and DVD
-ISOs, SD cards, and dozens more. libguestfs doesn't need root permissions.
-
-All this functionality is available through a convenient shell called
-guestfish, or use virt-rescue to get a rescue shell for fixing unbootable
-virtual machines.
