Unfortunately the --connect parameter doesn't let you access a disk on
a remote machine:
http://libguestfs.org/guestfs-faq.1.html#remote-libvirt-guests-cannot-be-...
It's not really possible the way you are doing it now. You will have
to run virt-df on the local machine. Perhaps use a tool like Ansible
(https://www.ansible.com/)?

[PATCH 0/2] Move ocaml-augeas copy to libguestfs repo

ocaml-augeas is used only by virtlibguestfs, so move it to this
repository, instead of having it around in the common submodule.
The removal from common will happen later.

Long running nbdkit tests
by Richard W.M. Jones
The nbdkit tests take a long time to run especially on armv7. To try
to get an idea of which tests take the most time, and since I happen
to have a qemu aarch64 *TCG* guest available, I ran the tests on that
guest.
A TCG guest is about the worst case for libguestfs, used by some
tests, since it uses double-nested TCG, and as you can see below there
are tests taking over 6 hours.
In fact I didn't complete the run yet. test-cow.sh is still running
(after 2+ hours) and there may be further tests to come.
Results:
06:43:00 PASS: test-cache.sh
06:37:48 PASS: test-cache-on-read.sh
[ test-cow.sh possibly here ]
00:35:41 PASS: test-partitioning3.sh
00:34:29 PASS: test-partitioning5.sh
00:34:03 PASS: test-linuxdisk-copy-out.sh
00:33:58 PASS: test-floppy.sh
00:30:45 PASS: test-partitioning2.sh
00:28:41 PASS: test-linuxdisk.sh
00:28:34 PASS: test-iso.sh
00:02:59 PASS: test-cache-max-size.sh
00:02:58 PASS: test-partitioning6.sh
00:02:55 PASS: test-partitioning4.sh
00:02:51 PASS: test-eflags.sh
00:01:11 PASS: test-export-name.sh
00:01:01 PASS: test-parallel-sh.sh
00:00:54 PASS: test-python.sh
00:00:44 PASS: test-sh-errors.sh
00:00:44 PASS: test-cacheextents.sh
00:00:41 PASS: test-sh-extents.sh
00:00:35 PASS: test-info-base64.sh
Ignoring the ones which take mere minutes (those run in seconds on
more reasonable hardware), here is a summary of how the tests are
implemented:
test-cache.sh Gx2 F D
test-cache-on-read.sh Gx2 F D
test-cow.sh Gx3 F
test-partitioning3.sh G
test-partitioning5.sh G F
test-linuxdisk-copy-out.sh G Dx4
test-floppy.sh G Dx2
test-partitioning2.sh G F
test-linuxdisk.sh G D
test-iso.sh G
D = using libguestfs download or similar APIs
F = using libguestfs "fill" APIs which write lots of data
G = guestfish
xN = runs multiple times
So there's quite a strong correlation between multiple runs of
guestfish, and using those two APIs, and time taken.
Rich.

[v2v PATCH 0/7] Various build fixes
by Pino Toscano
Just like the similar series that already went in for libguestfs [1],
do similar fixes also for virt-v2v, with additional fixes for the
builddir!=srcdir case.
This will also need the fix to subdir-rules.mk.
[1] https://www.redhat.com/archives/libguestfs/2019-December/msg00062.html
Pino Toscano (7):
Update common to latest
build: stop shipping files generated by configure
build: use the mlv2v library
build: do not ship generated sources
build: drop HAVE_OCAML conditionals
build: actually require libvirt
build: hopefully fix dependencies on generated files

[common PATCH] mlv2v: build as OCaml library

While there is only one OCaml source, build it as small library: this
way it is easier to use, and there is no need to copy the sources from
here.
