...ssage: hivex_close: do_hivex_close: you must call 'hivex-open' first to initialize the hivex handle This is the process flow: g = guestfs_create (); guestfs_add_drive_opts (g, diskFile,GUESTFS_ADD_DRIVE_OPTS_FORMAT, "raw",-1); guestfs_launch (g) char **roots = guestfs_inspect_os (g); guestfs_inspect_os returns NULL, guestfs_last_error(g) returns message above. And guestfs_last_errno(g) returns 0. However this same code works fine with a Server2008 image and an XP image. I copied the verbose output to pastebin: http://pastebin.com/U9Jb6JwH Suggestions?

This is (to say the least) awkward in guestfish, but much easier if you use a real programming language (libguestfs has many language bindings, see http://libguestfs.org). Also you are missing a call to &...

These three patches (two were previously posted) can do simple operating system inspection in C.

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:

From: "Richard W.M. Jones" <rjones at redhat.com> If the parent process uses a pipe (or any fd, but pipes are a particular problem), then the recovery process would hold open the file descriptor(s) of the pipe, meaning that it could not be fully closed in the parent. Because the recovery process doesn't use exec(2), this wasn't avoidable even using FD_CLOEXEC. Avoid this

Hi ,all : thanks for helping me ! I am using libguestfs-1.28.1 on ubuntu 12.04 to manage vm disk created by KVM. I downloaded libguestfs-1.28.1.tar.gz ,and then executed (1) ./autogen.sh (2) ./configure (3) make (4) make check .there is the error. /usr/Libvmi/libguestfs-1.28.1/run --test guest-aux/make-fedora-img.pl md_create: feature 'mdadm' is not available in this
