[PATCH v2] launch: add support for autodetection of appliance image format
by Pavel Butsykin
This feature allows you to use different image formats for the fixed
appliance. The raw format is used by default.

1.39 proposal: Let's split up the libguestfs git repo and tarballs
by Richard W.M. Jones
My contention is that the libguestfs git repository is too large and
unwieldy. There are too many separate, unrelated projects and as a
result of that the source has too many dependencies and takes too long
to build and test.
The project divides (sort of) naturally into layers -- the library,
the bindings, the various virt tools -- and could be split along those
lines into separate projects which can then be released and evolve at
their own pace.
My suggested split would be something like this:
* libguestfs: The library, daemon and appliance. That would include
the following directories in a single project:
appliance
bash
contrib
daemon
docs
examples
gnulib
lib
logo
test-tool
tmp
utils
website
* 1 project for each language binding:
csharp
erlang
gobject
golang
haskell
java
lua
ocaml
php
perl
python
ruby
* virt-customize and related tools, we'd probably call this subproject
"virt-builder". It would include virt-builder, virt-customize and
virt-sysprep, since they share a lot of common code.
* 1 project for each of the following items:
small tools written in C
(virt-cat, virt-filesystems, virt-log, virt-ls, virt-tail,
virt-diff, virt-edit, virt-format, guestmount, virt-inspector,
virt-make-fs, virt-rescue)
guestfish
virt-alignment-scan and virt-df
virt-dib
virt-get-kernel
virt-resize
virt-sparsify
virt-v2v and virt-p2v
virt-win-reg
* I'd be inclined to drop the legacy Perl tools virt-tar,
virt-list-filesystems, virt-list-partitions unless someone
especially wished to step forward to maintain them.
* common code and generator: Off to the side we'd somehow need to
package up the common code and the generator for use by all of the
above projects. It wouldn't be a separate project for downstream
packagers, but instead the code would be included (ie. duplicated)
in tarballs and upstream available as a side git repo that you'd
need to include when building (git submodule?). This is somewhat
unspecified.
M4, PO, and tests would be split between the projects as appropriate.
My proposal would be to do this incrementally, rather than all at
once, moving the easier things out first.
Thoughts?
Rich.

[nbdkit PATCH v2] plugin: add and use nbdkit_realpath
by Pino Toscano
Introduce a new helper function to resolve a path name, calling
nbdkit_error on failure: other than doing what nbdkit_absolute_path
does, it also checks that the file exists (and thus avoids errors later
on). To help distinguish it from nbdkit_absolute_path, improve the
documentation of the latter.
Apply it where an existing path is required, both in nbdkit itself and
in plugins.
Related to: https://bugzilla.redhat.com/show_bug.cgi?id=1527334

This change works, but since the original image came from virt-builder,
and virt-builder knows enough about the image to know that it should
install packages with dnf (or yum or apt-get or whatever is appropriate
for any given image), it should also have enough info available to
determine on its own that the selinux labels need to be redone.
Especially since the Fedora images provided by virt-builder have selinux
set to enforcing, I think the default behavior in this case should be
for virt-builder to relabel.
This patch fixes the problem for libvirt-tck, but I can imagine that
this same problem will be revisited time after time on IRC and the
libguestfs mailing list (once the user takes the obligatory
troubleshooting trip to discover the source of the problem). In this
case the initial symptom was "a guest that was never logged into by a
human was failing an automated test". There were several steps from
there to "dhcpc was failing to get an IP address due to bad selinux
labels", and then learning via IRC that the labels were incorrect
because extra packages are installed with the image mounted on the
libguestfs appliance, which runs with selinux disabled.
What is preventing virt-builder from automatically making a correct
determination about whether or not relabeling must be done?

[PATCH] lib: Don't abort if a signal handler calls exit(2) during a guestfs_* function.
by Richard W.M. Jones
$ virt-sparsify input output
[ 0.0] Create overlay file in /tmp to protect source disk
[ 0.0] Examine source disk
^C
guestfs_close: g->lock: Device or resource busy
Aborted (core dumped)
The reason for this is because virt-sparsify calls exit(2) in the
SIGINT signal handler, which causes the close_handles atexit handler
to run, which calls guestfs_close. However the same handle is in the
middle of a guestfs_* call, and the code in lib/handle.c catches this
case and calls abort(2).
(The same situation could happen from threaded code.)
The solution is to ignore the case where guestfs_close is called from
close_handles and the lock is held (the handle will be left open in
this case, but the recovery process should reap qemu).
