libguestfs Barcelona talk (20 minutes)

    "Libguestfs is a C library that provides a way to access and
    modify virtual machine disk images.  It uses qemu and the Linux
    kernel, so we can manipulate just about any disk image,
    filesystem, partitioning scheme, LVM, Windows disks, and more.
    Above this layer are many specialized "virt-*" tools for carrying
    out specific tasks.

    In this talk, Richard Jones will give a live demonstration of
    libguestfs and the virt tools, and talk about the new features
    available in libguestfs 1.20."

----------------------------------------------------------------------

Audience:
 - KVM developers

Interested in:
 - What they can use it for
 - How it works
 - Problems with KVM
 - New features, particularly ones which use new features in KVM

What do they want to do with images:
 - Viewing and file injection for personal use
 - Use in management tools like oVirt, OpenStack

New features of interest:
 - libvirt management of appliance
   . sVirt / SELinux
   . remote access
 - virtio-scsi
   . lots of disks
   . hot plugging of disks
   . sparsification

[---- OVERVIEW ----]

C library
nearly 400 different API calls

handout and website contains example programs

  NEXT SLIDE: 0300

manages a qemu subprocess, running a minimal Linux
  distro that we call the "appliance"

uses kernel code, qemu so supports
 - qcow2
 - VMDK
 - all filesystems
 - partitioning
 - LVM
 - etc

doesn't need root, doesn't create device nodes, is
  secure and well-behaved

  NEXT SLIDE: 0400

around the API is a whole ecosystem of tools, programs
and external projects

  - virt tools, in C, Perl, OCaml
  - OpenStack (Python)
  - BoxGrinder (Ruby)
  - Oz (Python)
  - virt-p2v, virt-v2v (Perl)


[---- NEW FEATURES IN LIBGUESTFS 1.20 ----]

libguestfs 1.20 should be released at the end of this year, after
a very long (7 month) development cycle.

Two major changes:

 - libvirt
 - virtio-scsi

Implies:

 . sVirt / SELinux
 . remote access
 . 255 disks
 . hot plugging of disks
