Libguestfs - Feb 2023 - [p2v PATCH v2 10/11] Reenable the OpenStack output mode

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1792141

V1 was at
<https://listman.redhat.com/archives/libguestfs/2023-January/030539.html>
(Message-Id: <20230130142228.108135-1-lersek at redhat.com>).

In v2, I've picked up Rich's R-b's for all patches except #9 and
#10.
Those have been updated; please see the Notes sections on them.

Laszlo

Alban Lecorps (1):
  Introduce "p2v.output.misc" for passing "-oo" options to
virt-v2v

Laszlo Ersek (10):
  test-virt-p2v-cmdline: turn option list into a shell array

The argument for virt-p2v's "--cmdline" option has grown huge.
Break it to
multiple lines. That's easiest to do with a shell array.

From: Alban Lecorps <alban.lecorps at ubisoft.com>

The "-oo" option will be useful primarily for the openstack output
mode
(currently disabled, from commit b74c126629e3, "Ignore 'openstack'
driver", 2020-03-16).

Use a ConfigStringList knob for "-oo", and for each OPTION=VALUE
element
in that list, create a separate "-oo OPTION=VALUE" option. Do this
because
there are too many "-oo" options, and because they are
output-dependent,
and because even virt-v2v "blindly" forwards some of those (such as
"-oo
os-*=*" for openstack).

The "p2v.oo" shorthand is not needed for compatibility, but it's
still a
good idea for user convenience.

(Various tweaks, documentation, and test case update, by Laszlo.)

 /**
  * Split string at separator character C<sep>, returning the list of
  * strings.  Returns C<NULL> on memory allocation failure.

Some of the overlong lines in "gui.c" originate from function calls
like

  config->whatever = strdup (gtk_entry_get_text (GTK_ENTRY (entry)));

These are hard to wrap -- we generally break the second and further
arguments in a function call to new lines, and start those new lines
aligned with the opening parenthesis of the function call. However, in the
above expression, each function only takes one parameter -- the problem is
the deep nesting, and our wrapping style generally strives to reflect
nesting.

Extract the expression to a small (somewhat accidental) helper function.
This function is then used from multiple dialogs (the connection dialog
and the conversion dialog).

In "gui.c", we use many long string literals, for labels, warnings,

Introduce a new GTK_ENTRY field in the Output options box.  Similarly to
"p2v.output.misc" on the kernel cmdline, the contents of this
GTK_ENTRY
are a comma-separated list of OPTION=VALUE options, where each option is
passed to virt-v2v as the argument of a separate "-oo" option.

Refresh the manual accordingly.

For initially populating the text entry (in case the kernel command line
specified "p2v.output.misc"), call the guestfs_int_join_strings()
function
that we imported previously in this series.

For unpacking the contents in start_conversion_clicked(), call
guestfs_int_split_string(), just like the generated kernel cmdline parser
does, in update_config_from_kernel_cmdline() [kernel-config.c].

 All output options and paths are relative to the conversion server
 (I<not> to the physical server).
 
+Note that the C<Misc. options> text entry behaves differently from the
+other text entries -- its format is identical to that of the
+C<p2v.output.misc> L<kernel command line|/KERNEL COMMAND LINE
+CONFIGURATION> option.  Namely, the text entry contains a
+comma-separated list of miscellaneous, output-specific options.  (Do
+not put spaces around the commas!)  Each element in the list is of the
+form C<OPTION=VALUE>, and each element is passed to virt-v2v as a
+standalone I<-oo OPTION=VALUE> option.

 Finally in the left hand column is an information box giving the
 version of virt-p2v (on the physical server) and virt-v2v (on the
 conversion server).  You should supply this information when reporting

With "-oo" exposed on the GUI, the reason for disabling the openstack
driver (from commit b74c126629e3, "Ignore 'openstack' driver",
2020-03-16)
is gone. Reenable the driver.

At the same time, add two small openstack-related hints to the GUI.

This is similar to commit 2d608e252bbe ("Add kickstart URLs for RHEL
8",
2020-02-18), but we also need to add EPEL-9 (cf. commit f4c7ae6ba98f,
"make-disk: inject EPEL9 repo in RHEL9 disk image", 2023-01-20).
