[RFC 0/4] meson: Enable -Wundef
by Andrea Bolognani
A few days ago I have posted a patch[1] that addresses an issue
introduced when a meson check was dropped but some uses of the
corresponding WITH_ macro were not removed at the same time.
That got me thinking about what we can do to prevent such scenarios
from happening again in the future. I have come up with something
that I think would be effective, but since applying the approach
throughout the entire codebase would require a non-trivial amount of
work, I figured I'd ask for feedback before embarking on it.
The idea is that there are two types of macros we can use for
conditional compilation: external ones, coming from the OS or other
libraries, and internal ones, which are the result of meson tests.
The external ones (e.g. SIOCSIFFLAGS, __APPLE__) are usually only
defined if they apply, so it is correct to check for their presence
with #ifdef. Using #if will also work, as undefined macros evaluate
to zero, but it's not good practice to use them that way. If -Wundef
has been passed to the compiler, those incorrect uses will be
reported (only on platforms where they are not defined, of course).
The internal ones (e.g. WITH_QEMU, WITH_STRUCT_IFREQ) are similar,
but in this case we control their definition. This means that using
means that the feature is not available on the machine we're building
on, but it could also mean that we've removed the meson check and
forgot to update all users of the macro. In this case, -Wundef would
work 100% reliably to detect the issue: if the meson check doesn't
exist, neither will the macro, regardless of what platform we're
building on.
So the approach I'm suggesting is to use a syntax-check rule to
ensure that internal macros are only ever checked with #if instead of
Of course this requires a full sweep to fix all cases in which we're
not already doing things according to the proposal. Should be fairly
easy, if annoying. A couple of examples are included here for
demonstration purposes.
The bigger impact is going to be on the build system. Right now we
generally only define WITH_ macros if the check passed, but that will
have to change and the result is going to be quite a bit of
additional meson code I'm afraid.
Thoughts?

Snapshot deletion does have something that can be considered force and
that is the '--metadata' option that removes just the snapshot
definition (metadata) and doesn't touch the disk images.

.. but going ahead with the snapshot deletion isn't always okay either.
The disk isn't referenced by the VM so the disk state can't be merged,
while the state would be merged for any other disk.
When reverting back to a previous snapshot, which is still referencing
the older state of the disk which was removed from the VM, the VM would
see that the image state of disks that were present at deletion would
contain the merged state, but only a partial state for the disk which
was later removed.

[libvirt PATCH] qemu_snapshot: allow reverting to external disk only snapshot
by Pavel Hrdina
When snapshot is created with disk-only flag it is always external
snapshot without memory state. Historically when there was not support
to revert external snapshots this produced error message.
error: Failed to revert snapshot s1
error: internal error: Invalid target domain state 'disk-snapshot'. Refusing snapshot reversion
Now we can simply consider this as reverting to offline snapshot as the
possible damage to file system is already done at the point of snapshot
creation.

[PATCH 00/20] qemu: support mapped-ram+directio+mulitfd
by Jim Fehlig
This series is essentially V1 of a prior RFC [1] to support QEMU's
mapped-ram stream format [2] and migration capability. Along with
supporting mapped-ram, it implements a design approach we discussed
for supporting parallel save/restore [3]. 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
With this series, saving and restoring using mapped-ram is enabled by
default if the underlying QEMU advertises the mapped-ram migration
capability. It can be disabled by changing the 'save_image_version'
setting in qemu.conf.
To use mapped-ram with QEMU:
- The 'mapped-ram' migration capability must be set to true
- The 'multifd' migration capability must be set to true and
the 'multifd-channels' migration parameter must set to a
value >= 1
- QEMU must be provided an fdset containing the migration fd(s)
- The 'migrate' qmp command is invoked with a URI referencing the fdset
and an offset where to start reading or writing the data stream, e.g.
{"execute":"migrate",
"arguments":{"detach":true,"resume":false,
"uri":"file:/dev/fdset/0,offset=0x11921"}}
The mapped-ram stream, in conjunction with direct IO and multifd, can
significantly improve the time required to save VM memory state. The
following tables compare mapped-ram with the existing, sequential save
stream. In all cases, the save and restore operations are to/from a
block device comprised of two NVMe disks in RAID0 configuration with
xfs (~8600MiB/s). The values in the 'save time' and 'restore time'
columns were scraped from the 'real' time reported by time(1). The
'Size' and 'Blocks' columns were provided by the corresponding
outputs of stat(1).

--------------------------------------------------------------------
As can be seen from the tables, one caveat of mapped-ram is the logical file
size of a saved image is basically equivalent to the VM memory size. Note
however that mapped-ram typically uses fewer blocks on disk.
Support for mapped-ram+direct-io only recently landed in upstream QEMU
and will first appear in the 9.1 release, which may complicate merging
support in libvirt. Specifically, I'm not sure how to detect if the
combination is supported by QEMU. Suggestions welcomed.
Similar to the RFC, V1 ignores compression. libvirt currently supports
compression by connecting 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. In general, we can consider
mapped-ram and compression incompatible and document they cannot be used
together.

[PATCH v3 0/5] ch: handle events from cloud-hypervisor
by Purna Pavan Chandra Aekkaladevi
changes from v2->v3:
* Remove patch 'utils: Implement virFileIsNamedPipe' as it is no more needed.
* Remove the eventmonitorpath only if it exists
* Added domain name as a prefix to logs from ch_events.c. This will make
debugging easier.
* Simplified event parsing logic by reserving a byte for null char.
changes from v1->v2:
* Rebase on latest master
* Use /* */ for comments
* Remove fifo file if already exists
* Address other comments from Praveen Paladugu
cloud-hypervisor raises various events, including VM lifecylce operations
such as boot, shutdown, pause, resume, etc. Libvirt will now read these
events and take the necessary actions, such as correctly updating the
domain state. A FIFO file is passed to `--event-monitor` option of
cloud-hypervisor. Libvirt creates a new thread that acts as the reader
of the fifo file and continuously monitors for new events. Currently,
shutdown events are handled by updating the domain state appropriately.
