[PATCH] run: Don't fail on missing LIBGUESTFS_PATH if --disable-appliance
by Hilko Bengen
Set LIBGUESTFS_PATH to the default value compiled into and output a
warning to STDERR, instead.
The previous behavior caused the build to abort when trying to build
the sysprep documentation -- without much of a hint of what went
wrong.
When LIBGUESTFS_PATH was not set, test-events.sh would fail.

[PATCH 0/1] guestfish: Tab-complete single / double quoted filenames containing space - introduce list_directory_entries() routine
by Jan Lieskovsky
This series provides support for tab completion also for single / double
quoted filenames, which can contain space.
Patch 0/1 - separates guestfs list directory content functionality
(from complete_dest_paths_generator()) into dedicated
list_directory_entries() routine, so it can be subsequently
re-used in other code places.
Patch 1/1 - introduces fish_completion_word_break_characters_hook for
guestfish (depends on list_directory_entries()).
Thank you && Regards, Jan.

support remotely mounting disk images in p2v
by Mo Morsi
Figure I'd share the latest revision to p2v I had regarding $subject.
The patch now applies against HEAD and compiles fine. I was able to update
the package on the client and run virt-p2v, though have yet to do a full
end-to-end verification
Most likely a little more work is needed to tidy up some edge cases and fully
flush things out, but the majority of the work should be in place.
On the client side the disk is exported using qemu-nbd and an new ssh forwarding
channel is opened up infront of it. The server simply instructs libguestfs to connect
to nbd://localhost:port/ and the rest is taken care of.

[PATCH] Fix compiler warning when libselinux is not present

static function selinux_warning() isn't used if HAVE_LIBSELINUX isn't

The quoting problem happens when someone writes a program which takes
(eg) a hostname string from the user and passes it unmodified to the
guestfs API. It's an issue if this string can cause unexpected [even
malicious/exploitable] things to happen when passed unquoted on the
qemu command line.

remotely mounting client disks in p2v server
by Mo Morsi
Just spent a little time poking around w/ p2v and am attaching the
following pseudo-code for consideration. Note the patches aren't commit
ready yet, just looking for thoughts
- The first is a fix to get client image building process working on F17.
It seems the version of ksflatten there didn't expand the nested %includes
which was causing errors (also --interpreter image-minimizer resulted in errors)
- The next patch adds an option to the ui to allow the user to specify that
they would like to mount a disk as opposed to copy it to the server. This
option is currently mutually exclusive w/ the 'convert' checkbox.
An option still needs to be added to the ui to toggle how to export the
local disks (nbd, iscsi, etc). Would adding this as a global flag (eg applies
to all disks) work?
- The next patch stubs out some code which to process the disks for which 'mount'
was select. The actual calls to export the nbd/iscsi disk have yet to be added
though the mount command is issued to the server.
- The final patch stubs out the corresponding server side functionality which interprets
the mount command and includes placeholders to connect to the remote uri locally
and pass the remote disks onto the converter.
The commands to setup the nbd/iscsi server and client (on the p2v client and server respectively)
are simple enough though I still have to look into how to use the existing ssh tunnel
for security.
Does this looks to be in about the right direction? Other thoughts?
