[guestfs-tools PATCH] sysprep: remove system-local NetworkManager connection profiles (keyfiles)
by Laszlo Ersek
Add a simple (default) operation to remove
/etc/NetworkManager/system-connections/*.nmconnection
which arguably carry stale information after the initial creation of the
system disk image.
Note: no side effect callback is invoked. Before commit 576f1541a20c
("sysprep: Use customize module for customizing the guest after
sysprepping.", 2014-03-25), the "delete" operation had been native to
virt-sysprep ("sysprep/sysprep_operation_delete.ml"), and it didn't invoke
side effects. In said commit, "delete" was delegated to virt-customize,
and that was when "side_effects#created_file" was introduced (most likely)
as a catch-all. (We still have the "XXX Did we?" comment today.)

Notes:
Tested with:
$ virt-sysprep -v -x --enable=net-nmconn \
-a CentOS-Stream-GenericCloud-9-20211201.1.x86_64.qcow2
(Download directory:
<https://cloud.centos.org/centos/9-stream/x86_64/images/>.)
Log excerpt:
> libguestfs: trace: inspect_get_distro = "centos"
> libguestfs: trace: glob_expand "/etc/NetworkManager/system-connections/*.nmconnection"
> [...]
> libguestfs: trace: glob_expand = ["/etc/NetworkManager/system-connections/ens3.nmconnection"]
> libguestfs: trace: rm_f "/etc/NetworkManager/system-connections/ens3.nmconnection"
> [...]
> libguestfs: trace: rm_f = 0
And indeed the file got removed (checked with guestfish afterwards).

[virt-v2v wave 2 PATCH v2 00/16] replace QXL (and Cirrus) with standard VGA
by Laszlo Ersek
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1961107
v1: https://listman.redhat.com/archives/libguestfs/2021-November/msg00150.html
Please see the v2 changes (relative to the v1 posting) in the Notes
sections of the individual patches.
The v2v QE team at Red Hat has helped a lot with testing (see again the
per-patch v2 notes); the only part that still needs good test results is
the OVF output.
