I'm using a Windows raw disk image that is "converted" to the VDI format by custom code that prepends a header to the image. I use 'vdi' for GUESTFS_ADD_DRIVE_OPTS_FORMAT of guestfs_add_drive_opts(). After launching the appliance, the call to guestfs_list_partitions() results in an empty list. Is there a way to add the drive but have an offset into the image file as a "starting point"? So that it could skip the header which apparently is causing the issue....

I'm using qemu-nbd to setup the device with an offset into the image. Using libguestfs version 1.21.22 Code for adding the drive: char *server[] = { "localhost:3000", NULL }; if (guestfs_add_drive_opts (g, "" /* export name - see below */, GUESTFS_ADD_DRIVE_OPTS_FORMAT, "raw", GUESTFS_ADD_DRIVE_OPTS_PROTOCOL, "nbd", GUESTFS_ADD_DRIVE_OPTS_SERVER, server, -1) Here is some of the stdout.

From: Nikolay Ivanets <stenavin@gmail.com> This patch adds 4096 bytes sector size for output disk. Side notes: While working on this patch I reveal long standing issue: virt-make-fs can fail if source directory/archive contains certain amount of really small or empty files or wide tree of directories. That is because of lack of available inodes on a small file system to keep files

These two patches make appliance building thread-safe. The first adds a test which easily demonstrates the problem. The second fixes the issue. For more information see Ian McLeod's analysis of the bug here: https://bugzilla.redhat.com/show_bug.cgi?id=790528#c5 Rich.

In libguestfs we have a few tests that require root privileges and they are skipped by default (normally you should not build or test as root), but you can do this to run them: sudo make check-root In nbdkit I wanted to check that the file plugin works with block devices (this is not tested), and the only way I can sensibly think to do this is using a loopback device and root.

v2 was here: https://www.redhat.com/archives/libguestfs/2020-March/msg00154.html v3: - Micro-optimize tmpdir. - Quote $disk in default command shell fragment. - Don't redirect mkfs output to /dev/null. Instead use exec </dev/null >/dev/null before the shell fragment. We may want to do this in other places where we run external shell scripts, or more generally for all

To avoid bitrot, any new feature needs testsuite coverage ;) Still to come: once I get my work on parallel nbd finished, I will add a test-parallel-nbd.sh that closely mirrors what my other series added in test-parallel-file.sh. If desired, it might be a fun exercise to tweak test-nbd into using a for-loop of user-controlled depth for how deep you want to nest the forwarding tree, to see where

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

Note this patch requires a non-upstream qemu patch that I've been experimenting with. See qemu-devel list. Rich.
