[PATCH 0/2] qemu: Clarify purpose of image format settings
by Jim Fehlig
The current documentation of the various foo_image_format settings in
qemu.conf subtly implies they are only used for specifying compression.
Patch1 of this small series attempts to clarify and improve the description
of the settings. It defines image format as a way to specify the desired
layout of guest memory blocks on disk.
Patch2 changes the name of the 'compressed' field of virQEMUSaveHeader to
'format', removing implication that format == compressed in the code.

[PATCH RFC 0/9] qemu: Support mapped-ram migration capability
by Jim Fehlig
This series is a RFC for support of QEMU's mapped-ram migration
capability [1] for saving and restoring VMs. It implements the first
part of the design approach we discussed for supporting parallel
save/restore [2]. In summary, the approach is
1. Add mapped-ram migration capability
2. Steal an element from save header 'unused' for a 'features' variable
and bump save version to 3.
3. Add /etc/libvirt/qemu.conf knob for the save format version,
defaulting to latest v3
4. Use v3 (aka mapped-ram) by default
5. Use mapped-ram with BYPASS_CACHE for v3, old approach for v2
6. include: Define constants for parallel save/restore
7. qemu: Add support for parallel save. Implies mapped-ram, reject if v2
8. qemu: Add support for parallel restore. Implies mapped-ram.
Reject if v2
9. tools: add parallel parameter to virsh save command
10. tools: add parallel parameter to virsh restore command
This series implements 1-5, with the BYPASS_CACHE support in patches 8
and 9 being quite hacky. They are included to discuss approaches to make
them less hacky. See the patches for details.
The QEMU mapped-ram capability currently does not support directio.
Fabino is working on that now [3]. This complicates merging support
in libvirt. I don't think it's reasonable to enable mapped-ram by
default when BYPASS_CACHE cannot be supported. Should we wait until
the mapped-ram directio support is merged in QEMU before supporting
mapped-ram in libvirt?
For the moment, compression is ignored in the new save version.
Currently, libvirt connects the output of QEMU's save stream to the
specified compression program via a pipe. This approach is incompatible
with mapped-ram since the fd provided to QEMU must be seekable. One
option is to reopen and compress the saved image after the actual save
operation has completed. This has the downside of requiring the iohelper
to handle BYPASS_CACHE, which would preclude us from removing it
sometime in the future. Other suggestions much welcomed.
Note the logical file size of mapped-ram saved images is slightly
larger than guest RAM size, so the files are often much larger than the
files produced by the existing, sequential format. However, actual blocks
written to disk is often lower with mapped-ram saved images. E.g. a saved
image from a 30G, freshly booted, idle guest results in the following
'Size' and 'Blocks' values reported by stat(1)
Size Blocks
sequential 998595770 1950392
mapped-ram 34368584225 1800456
With the same guest running a workload that dirties memory
Size Blocks
sequential 33173330615 64791672
mapped-ram 34368578210 64706944

[PATCH v3 0/4] multiple memory backend support for CPR Live Updates
by mgalaxy＠akamai.com
From: Michael Galaxy <mgalaxy(a)akamai.com>
CPR-based support for whole-hypervisor kexec-based live updates is
now finally merged into QEMU. In support of this, we need NUMA to be
supported in these kinds of environments. To do this we use a technology
called PMEM (persistent memory) in Linux, which underpins the ability for
CPR Live Updates to work so that QEMU memory can remain in RAM and
be recovered after a kexec operationg has completed. Our systems are highly
NUMA-aware, and so this patch series enables NUMA awareness for live updates.
Further, we make a small change that allows live migrations to work
between *non* PMEM-based systems and PMEM-based systems (and
vice-versa). This allows for seemless upgrades from non-live-compatible
systems to live-update-compatible sytems without any downtime.
Changes since v2:
1. Corrected invalid privateData casts and re-organized variables and
error codes.
2. Re-ran ninja test and corrected formatting
3. Tested that individual patches apply and build cleanly.
4. Separated out NEWS item into separate patch
Michael Galaxy (4):
qemu.conf changes to support multiple memory backend
Support live migration between file-backed memory and anonymous
memory.
Update configuration file documentation to support multiple memory
backends

[PATCH] conf: Check for bandwidth limits during parsing
by Michal Privoznik
The 'tc' program stores speeds in 64bit integers (unit is bytes
per second) and sizes in uints (unit is bytes). We use different
units: kilobytes per second and kibibytes and therefore we can
parse values larger than 'tc' can handle. Reject those values
right away.
And while at it, fix the schema which assumed speed values fit
into uint.

[PATCH] virnetlibsshsession: Reflect API change in libssh
by Michal Privoznik
As of libssh commit of libssh-0.11.0~70 [1] the
ssh_channel_get_exit_status() function is deprecated and a new
one is introduced instead: ssh_channel_get_exit_state().
It's not a drop-in replacement, but it's simple enough.
Adapt our libssh handling code to this change.

[PATCH] glibcompat: remove obsolete clang workaround
by Daniel P. Berrangé
This mostly reverts commit 65491a2dfe00bfcf9f09a8d6eab60234b56c8cc4.
There was a bug introduced in glib 2.67.0 which impacted libvirt with
clang causing -Wincompatible-pointer-types-discards-qualifiers warnings.
This was actually fixed quite quickly in 2.67.1 with
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719
Our workaround was then broken with glib 2.81.1 due to commit
14b3d5da9019150d821f6178a075d85044b4c255 changing the signature of the
(private) macro we were overriding.
Since odd-number glib releases are development snapshots, and the
original problem was only present in 2.67.0 and no other releases,
just drop the workaround entirely.
