[p2v PATCH 00/15] recognize block device nodes (such as iSCSI /dev/sdX) added via XTerm
by Laszlo Ersek
- Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=2124538
- Based on:
[p2v PATCH 0/4] fix crash in "v2v_version" string lifecycle management
https://listman.redhat.com/archives/libguestfs/2022-September/029869.html
Message-Id: <20220911142501.18230-1-lersek(a)redhat.com>
The first 13 patches are (mainly) refactorings and (occasionally) fixes
for small warts.
Patch#14 introduces a "Refresh disks" button, and extends the manual
accordingly.
Patch#15 adds a new section to the manual ("ACCESSING ISCSI DEVICES")
which explains how to set up iSCSI LUNs from the XTerm / shell window,
and how to expose the new /dev/sdX block device nodes to the running
virt-p2v process with the "Refresh disks" button.
Actual conversion of a physical Windows 2022 installation, from an iSCSI
OS disk, tested by Vera Wu in
<https://bugzilla.redhat.com/show_bug.cgi?id=2124538#c19>.
Laszlo
Laszlo Ersek (15):
set_from_ui_generic(): eliminate small code duplication
set_interfaces_from_ui(): open-code the set_from_ui_generic() logic
gui.c: consume "all_disks" and "all_removables" only for dialog setup
compare(): move to "utils.c", rename to compare_strings()
find_all_disks(): extract (plus friends) to new file "disks.c"
find_all_disks(): minimize global variable references
populate_disks(), populate_removable(): minimize references to globals
set_config_defaults(): clean up some warts
set_config_defaults(): hoist find_all_disks() call to main()
gui.c: remove "all_disks" and "all_removable" global variable
references
"all_disks", "all_removable": eliminate
gui.c: extract GtkListStore-filling loops for "disks" and "removable"
create_conversion_dialog(): make "start_button" local
create_conversion_dialog(): add button to refresh disks & removables
virt-p2v.pod: explain how to bring iSCSI LUNs to the disk selection
dialog

[p2v PATCH 0/4] fix crash in "v2v_version" string lifecycle management
by Laszlo Ersek
We free the "v2v_version" string with a wrong function, which may cause
a crash. The last patch fixes this problem. The first three patches work
toward eliminating shadowed identifiers, because shadowing impeded my
analysis of "v2v_version"'s life cycle.

miniexpect: upgrade to miniexpect with PR#1
eliminate shadowing of global variables

Re: [Libguestfs] ZFS-on-NBD
by Richard W.M. Jones
As an aside, we'll soon be adding the feature to use nbdkit plugins as
Linux ublk (userspace block) devices. The API is nearly the same so
there's just a bit of code needed to let nbdkit plugins be loaded by
ubdsrv. Watch this space.
Of course it may not (probably will not) fix other problems you mentioned.
Rich.

Libguestfs + e2fsprogs
by Jevin Gala
Hi,
I wanted to use a higher version of e2fsprogs (1.45) with libguestfs 1.28.
Can I get some information on how I can proceed or use the one compiled on
the server separately ?

[p2v PATCH v2 0/6] restrict vCPU topology to (a) fully populated physical, or (b) 1 * N * 1
by Laszlo Ersek
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1590721
v1: https://listman.redhat.com/archives/libguestfs/2022-September/029806.html
Please see the Notes section on each patch for the updates in this
version (addressing v1 feedback). Patch #5 is a candidate for dropping
in particular.
I'm also including a range-diff between v1 and v2, below.
