[libvirt PATCH v2 0/3] ci: Check spelling
by Tim Wiederhake
This is a wrapper for codespell [1], a spell checker for source code.
Codespell does not compare words to a dictionary, but rather works by
checking words against a list of common typos, making it produce fewer
false positives than other solutions.
The script in this patch works around the lack of per-directory ignore
lists and some oddities regarding capitalization in ignore lists.
[1] (https://github.com/codespell-project/codespell/)
V1: https://listman.redhat.com/archives/libvir-list/2021-October/msg00015.html
The wrapper script changed since it was Reviewed-by: Ján, hence I did not mark
patch #2 as already reviewed.
Regards,
Tim

[PATCH v2] report error when virProcessGetStatInfo() is unable to parse data
by Ani Sinha
Currently virProcessGetStatInfo() always returns success and only logs error
when it is unable to parse the data. Make this function actually report the
error and return a negative value in this error scenario.
Fix the callers so that they do not override the error generated.

[libvirt PATCH v5 00/20] qemu: Introduce hvf domain type for Hypervisor.framework
by Andrea Bolognani
In order to hopefully address [libvirt#147] at long last, I've picked
up Roman's patches from 2018 and attempted to forward-port them.
More specifically, I've used the [roolebo/hvf-domain] branch as a
starting point, since it seems to contain a few improvements over
[v2] and was just easier to pick up.
The code is mostly his own, so I've retained the existing authorship
information, but I've dropped Reviewed-by tags for commits that have
been modified in non-trivial ways. I've applied very minimal style
tweaks along the way, but overall I've tried to modify the existing
patches as little as possible.
I've added a few changes of my own, which I've marked as "fixup!"
when I felt that they should be squashed into the previous patch
rather than existing as separate commits.
The new test cases, such as they are, pass, and no regressions to KVM
support appear to have been introduced in the process. I don't
currently have access to a machine running macOS, so I can't verify
that it's actually possible to start a hardware-accelerated VM by
myself, but a user has confirmed on the GitLab issue that the new
feature works.
Changes from [v4]:
* fixed an issue that prevented machine types from being probed
correctly, effectively making the entire thing non functional;
* only report HVF support as available when the guest architecture
and the host architecture match.
Changes from [v3]:
* reintroduced the patch that was missing in the initial version
of the forward-port;
* converted the documentation to reStructuredText and trimmed it
significantly;
* reworked virQEMUCapsAccelStr() based on Dan's suggestions;
* reworked macOS support in the test suite based on Dan's
suggestions;
* fixed a few minor issues found while doing the above.
Changes from [v2]:
* rebased on top of master;
* added a couple of simple test cases.

* GitLab: [abologna/hvf]
* CI: [pipeline]

+
+SYNOPSIS
+========
+
+``libvirt-guests`` *COMMAND*
+
+
+DESCRIPTION
+===========
+
+``libvirt-guests`` is a service that can be used to coordinate guest and host
+lifecyle actions. By default, ``libvirt-guests`` will suspend running guests
+when the host shuts down, and restore them to their pre-shutdown state when
+the host reboots.
+
+``libvirt-guests`` is typically under control of systemd. When
+``libvirt-guests.service`` is enabled, systemd will call ``libvirt-guests``
+with the ``start`` *command* when the host boots. Conversely, systemd will call
+``libvirt-guests`` with the ``stop`` *command* when the host shuts down.
+
+``libvirt-guests`` can be used directly. In addition to the ``start`` and
+``stop`` *commands*, it also supports ``status``, ``restart``, ``condrestart``,
+``try-restart``, ``reload``, ``force-reload``, ``gueststatus``, and
+``shutdown`` *commands*.
+
+
+ENVIRONMENT
+===========
+
+The following environment variables can be used to alter the behavior of
+``libvirt-guests``
+
+- URIS=default
+
+ URIs to check for running guests
+
+- ON_BOOT=start
+
+ Action taken on host boot
+
+ * start
+
+ All guests which were running on shutdown are started on boot regardless
+ of their autostart settings
+
+ * ignore
+
+ ``libvirt-guests`` won't start any guest on boot, however, guests marked
+ as autostart will still be automatically started by libvirtd
+
+- START_DELAY=0
+
+ Number of seconds to wait between each guest start. Set to 0 to allow parallel
+ startup.
+
+- ON_SHUTDOWN=suspend
+
+ Action taken on host shutdown
+
+ * suspend
+
+ All running guests are suspended using virsh managedsave
+
+ * shutdown
+
+ All running guests are asked to shutdown. Please be careful with this
+ settings since there is no way to distinguish between a guest which is
+ stuck or ignores shutdown requests and a guest which just needs a long
+ time to shutdown. When setting ON_SHUTDOWN=shutdown, you must also set
+ SHUTDOWN_TIMEOUT to a value suitable for your guests.
+
+- PARALLEL_SHUTDOWN=0
+
+ Number of guests will be shutdown concurrently, taking effect when
+ "ON_SHUTDOWN" is set to "shutdown". If Set to 0, guests will be shutdown one
+ after another. Number of guests on shutdown at any time will not exceed number
+ set in this variable.
+
+- SHUTDOWN_TIMEOUT=300
+
+ Number of seconds we're willing to wait for a guest to shut down. If parallel
+ shutdown is enabled, this timeout applies as a timeout for shutting down all
+ guests on a single URI defined in the variable URIS. If this is 0, then there
+ is no time out (use with caution, as guests might not respond to a shutdown
+ request). The default value is 300 seconds (5 minutes).
+
+- BYPASS_CACHE=0
+
+ If non-zero, try to bypass the file system cache when saving and
+ restoring guests, even though this may give slower operation for
+ some file systems.
+
+ - SYNC_TIME=1
+
+ If non-zero, try to sync guest time on domain resume. Be aware, that
+ this requires guest agent with support for time synchronization
+ running in the guest. By default, this functionality is turned off.
+
+
+BUGS
+====
+
+Please report all bugs you discover. This should be done via either:
+
+#. the mailing list
+
+ `https://libvirt.org/contact.html <https://libvirt.org/contact.html>`_
+
+#. the bug tracker

[PATCH] virsh-network: Don't check for virshXXXTypeFromString() >= VIR_XXX_LAST
by Michal Privoznik
They way our VIR_ENUM_IMPL() and virXXXTypeFromString() work is
that for any string that's not recognized a negative one is
returned. And, since VIR_XXX_LAST is passed to VIR_ENUM_IMPL() we
can be sure that all enum members are covered. Therefore, there
is no way that virXXXTypeFromString() can return a value that's
bigger or equal to VIR_XXX_LAST.
I've noticed two places where such comparison was made, both in
cmdNetworkUpdate(). Drop them.

[libvirt PATCH] meson: Fix yajl workaround

Recent versions of Meson report
WARNING: pkgconfig variable 'cflags' not defined for dependency yajl.
which makes sense, because "cflags" is not one of the variables
reported by
$ pkg-config --print-variables yajl
and
$ pkg-config --variable=cflags yajl
doesn't work either.
Use "includedir", which is a proper pkg-config variable,
instead.

[PATCH v3 00/12] Add riscv kvm accel support
by Yifei Jiang
This series adds both riscv32 and riscv64 kvm support, and implements
migration based on riscv.
Because of RISC-V KVM has been merged into the Linux master, so this
series are changed from RFC to patch.
Several steps to use this:
1. Build emulation
$ ./configure --target-list=riscv64-softmmu
$ make -j$(nproc)
2. Build kernel
3. Build QEMU VM
Cross built in riscv toolchain.
$ PKG_CONFIG_LIBDIR=<toolchain pkgconfig path>
$ export PKG_CONFIG_SYSROOT_DIR=<toolchain sysroot path>
$ ./configure --target-list=riscv64-softmmu --enable-kvm \
--cross-prefix=riscv64-linux-gnu- --disable-libiscsi --disable-glusterfs \
--disable-libusb --disable-usb-redir --audio-drv-list= --disable-opengl \
--disable-libxml2
$ make -j$(nproc)
4. Start emulation
$ ./qemu-system-riscv64 -M virt -m 4096M -cpu rv64,x-h=true -nographic \
-name guest=riscv-hyp,debug-threads=on \
