[PATCH 0/4] hw/s390x: Alias @dump-skeys -> @dump-s390-skey and deprecate
by Philippe Mathieu-Daudé
We are trying to unify all qemu-system-FOO to a single binary.
In order to do that we need to remove QAPI target specific code.
@dump-skeys is only available on qemu-system-s390x. This series
rename it as @dump-s390-skey, making it available on other
binaries. We take care of backward compatibility via deprecation.

hw/s390x: Introduce the @dump-s390-skeys QMP command
hw/s390x: Introduce the 'dump_s390_skeys' HMP command

[libvirt] [PATCH] Fix python error reporting for some storage operations
by Cole Robinson
In the python bindings, all vir* classes expect to be
passed a virConnect object when instantiated. Before
the storage stuff, these classes were only instantiated
in virConnect methods, so the generator is hardcoded to
pass 'self' as the connection instance to these classes.
Problem is there are some methods that return pool or vol
instances which aren't called from virConnect: you can
lookup a storage volume's associated pool, and can lookup
volumes from a pool. In these cases passing 'self' doesn't
give the vir* instance a connection, so when it comes time
to raise an exception crap hits the fan.
Rather than rework the generator to accomodate this edge
case, I just fixed the init functions for virStorage* to
pull the associated connection out of the passed value
if it's not a virConnect instance.
Thanks,
Cole

[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 v2 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.
Michael Galaxy (4):
qemu.conf changes to support multiple memory backend
Support live migration between file-backed memory and anonymous
memory.
Update unit test to support multiple memory backends

[PATCH rfcv4 00/13] LIBVIRT: X86: TDX support
by Zhenzhong Duan
Hi,
This series brings libvirt the x86 TDX support.
* What's TDX?
TDX stands for Trust Domain Extensions which isolates VMs from
the virtual-machine manager (VMM)/hypervisor and any other software on
the platform.
To support TDX, multiple software components, not only KVM but also QEMU,
guest Linux and virtual bios, need to be updated. For more details, please
check link[1].
This patchset is another software component to extend libvirt to support TDX,
with which one can start a TDX guest from high level rather than running qemu
directly.
* Misc
As QEMU use a software emulated way to reset guest which isn't supported by TDX
guest for security reason. We simulate reboot for TDX guest by kill and create a
new one in FakeReboot framework.
Complete code can be found at [2], matching qemu code can be found at [3].
There is a 'debug' property for tdx-guest object which isn't in matching qemu[3]
yet. I keep them intentionally as they will be implemented in qemu as extention
series of [3].
* Test
start/stop/reboot with virsh
stop/reboot trigger in guest
stop with on_poweroff=destroy/restart
reboot with on_reboot=destroy/restart
* Patch organization
- patch 1-4: Support query of TDX capabilities.
- patch 5-8: Add TDX type to launchsecurity framework.
- patch 9-11: Add reboot support to TDX guest
- patch 12-13: Add test and docs
TODO:
- update QEMU capabilities data in tests, depending on qemu TDX merged beforehand
- add reconnect logic in virsh command

[PATCH V2 0/4] Rework qemu internal active snapshots to use QMP
by Nikolai Barybin
Den, Peter, Daniel thank you for your comments!
I'm sending v2 of this patchset.
Changes since last revision:
- dropped [PATCH 4/4] qemu monitor: reap qemu_monitor_text
- added new patch: qemu capabilities: add QEMU_CAPS_SNAPSHOT_SAVE/_DELETE
- preserved old-style snapshotting (HMP savevm) in case we have QEMU < 6.0
- enhanced requirements for allowing snapshotting. All writable disks
should be qcow2, non-shared. If such disks exist and we have qcow2
NVRAM, add NVRAM device to the list of wrdevs. But never save vmstate
to NVRAM
- make char** wrdevs list allocation inside
qemuSnapshotActiveInternalGetWrdevListHelper()
