This is a first attempt to build libguestfs with just a ocaml bytecode compiler. The three tools written in ocaml will be build only when an ocamlopt compiler is available.

[PATCH] sysprep: handle distro specific sysv scripts

by Olaf Hering

Currently firstboot would only work on redhat-based images. Handle redhat-based, suse-based and debian guests, error out in case of an unknown distro. Update firstboot.sh: - make sure scripts exists and can be executed - add LSB header to avoid insserv warnings later on - run script only if called with "start" Update functions, pass only required options.

libguestfs for RHEL 6.5 preview repository

by Richard W.M. Jones

In RHEL 6.5 we are probably going to rebase libguestfs, febootstrap and virt-v2v. As usual when this happens, I've put up a preview repository: http://oirase.annexia.org/tmp/libguestfs-RHEL-6.5/ If you want to use these packages, the easiest thing to do is to copy the attached file into /etc/yum.repos.d/ and simply install or upgrade libguestfs. If you want to test libguestfs, obviously run 'libguestfs-test-tool' and also try a few things here: http://libguestfs.org/guestfs-testing.1.html ** These packages aren't signed and aren't guaranteed to work and ** ** aren't supported by Red Hat. Use them at your own peril. ** Feedback is welcomed on this list. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming blog: http://rwmj.wordpress.com Fedora now supports 80 OCaml packages (the OPEN alternative to F#)

Ubuntu and ZFS

by Tim Fletcher

Moved from Richard's blog to here.... A couple of people have requested removing the dependency on zfs-fuse from the ubuntu packages that Richard released last week, and there is some confusion about the state of ZFS in Ubuntu. There are 2 Linux compatible implementations of ZFS, zfs-fuse (http://gitweb.zfs-fuse.net/) and ZFS on Linux (http://zfsonlinux.org/). ZFS-fuse is in the official Ubuntu repos but is rather outdated and almost all development has stopped. ZFS on Linux (aka ZoL) is an open source but license incompatible kernel module that is under active development and released as source packages for most major distos. There is a ppa for Ubuntu here: https://launchpad.net/~zfs-native/+archive/stable ZoL is actively used in various NAS distros, as well as things like proxmox. I am currently using it as a backup target combined with rsync and snapshots. ZFS-fuse and ZoL packages can't be installed together and so installing guestfish which depends on zfs-fuse causes removal of the ZoL packages. -- Tim Fletcher <tim(a)night-shade.org.uk>

[PATCH] Change fallback name for external supermin helper

by Olaf Hering

Use basename of external helper instead of 'no' for external supermin helpers. This gives a clear error messages what binary is actually missing, and it is now possible to install the missing package without recompiling libguestfs. In addition its now also possible to use private builds of supermin (if they are in PATH) with a given libguestfs binary package.

ATTN: Denial of service attack possible on libguestfs 1.21.x, libguestfs.1.22.0

by Richard W.M. Jones

There's a denial of service attack possible from guests on any program that does inspection (eg. virt-inspector, many other virt-* tools, virt-v2v, OpenStack). The attack causes the host process to crash because of a double free. It's probably not exploitable (definitely not on Fedora because of the default memory hardening settings). This patch contains the fix and a reproducer: https://github.com/libguestfs/libguestfs/commit/fa6a76050d82894365dfe3291... This affects libguestfs >= 1.21.6 and libguestfs 1.22.0 and 1.23.0. I will include the fix in libguestfs >= 1.22.1 and >= 1.23.1.

How to use libguestfs access LVM as non-root user?

by Qiu Yu

Hi, Following code snippet, running as non-root user, will throw up a 'Permission denied' RuntimeError. Could someone kindly guide me the correct way to handle LVM disk as non-root user? Cause as http://libguestfs.org homepage claims, "libguestfs doesn't need root permissions." A little confused somehow. import guestfs g = guestfs.GuestFS() g.add_drive_opts("/dev/vg0/disk1", format="raw") Thanks! -- Qiu Yu
