[PATCH 0/4] qemu_tmp: Generate log file path for emulated TPMs more frequently
by Michal Privoznik
The real fix is in 2/4 and the rest is just cleanups.
Long story short, the path to log file is not stored anywhere and thus
is forgotten on libvirtd restart which means it's seclabel is not
restored properly.
Michal Prívozník (4):
qemu_tpm: Move logfile path generation into a separate function
qemu_tpm: Generate log file path among with storage path
qemu_tpm: Drop @logDir argument from qemuTPMEmulatorPrepareHost()
virtmp: Fix @path handling in virTPMEmulatorInit()

[libvirt PATCH v4 00/25] Add support for persistent mediated devices
by Jonathon Jongsma
This patch series follows the previously-merged series which added support for
transient mediated devices. This series expands mdev support to include
persistent device definitions. Again, it relies on mdevctl as the backend.
It follows the common libvirt pattern of APIs by adding the following new APIs
for node devices:
- virNodeDeviceDefineXML() - defines a persistent device
- virNodeDeviceUndefine() - undefines a persistent device
- virNodeDeviceCreate() - starts a previously-defined device
It also adds virsh commands mapping to these new APIs: nodedev-define,
nodedev-undefine, and nodedev-start.
Since we rely on mdevctl for the definition of mediated devices, we need a way
to stay up-to-date with devices that are defined by mdevctl (outside of
libvirt). The method for staying up-to-date is currently a little bit crude
due to the fact that mdevctl does not emit any events when new devices are
added or removed. As a workaround, we create a file monitor for the mdevctl
config directory and re-query mdevctl when we detect changes within that
directory. In the future, mdevctl may introduce a more elegant solution.
Changes in v4:
- rebase to git master
- switch to throwaway thread for querying mdevctl
- fixed a bug when removing devices because I was accidentally using
virHashForEach() instead of virHashForeachSafe()
- use DEFINED/UNDEFINED events instead of STARTED/STOPPED events
- changes related to merging information about mdev devices from both udev a=
nd
mdevctl:
- Re-used the same function to copy extra data from mdevctl regardless of
whether we're processing a udev event or a mdevctl event (recommended by
Erik). This results in slightly more complex handling of the object
lifetimes (see patch 9), but it consolidates some code.
- nodeDeviceDefCopyFromMdevctl() previously only copied the data that was
unique to mdevctl and didn't exist in udev. It now copies additional data
(possibly overwriting some udev). This solves a problem where a device =
is
defined but not active (i.e. we have not gotten any data from udev), and
then changed (e.g. somebody calls 'mdevctl modify' to change the mdev
type), but libvirt was not updating to the new definition.
- fix a bug where we were mistakenly emitting 'update' events for devices th=
at
had not changed
- Added the ability to specify a uuid for an mdev via device XML.
- split some commits into multiple patches
- updated new API version info to 7.1.0
- Fixed a bug reported by Yan Fu which hangs the client when attempting to
destroy a nodedev that is in use by an active vm. See
https://www.redhat.com/archives/libvir-list/2021-February/msg00116.html for
solution suggested by Alex.
- numerous smaller fixes from review findings
changes in v3:
- streamlined tests -- removed some unnecessary duplication
- split out patch to factor out node device name generation function
- split nodeDeviceParseMdevctlChildDevice() into a separate function
- added follow-up patch to remove space-padded alignment in header
- refactored the mdevctl update handling significantly:
- no longer a separate persistent thread that gets signaled by a timer
- now piggybacks onto the existing udev thread and signals the thread in t=
he
same way that the udev event does.
- Daniel suggested spawning a throw-away thread to handle mdevctl updates,
but that introduces the complexity of possibly serializing multiple
throw-away threads (e.g. if we get an 'created' event followed immediate=
ly
by a 'deleted' event, two threads may be spawned and we'd need to ensure
they are properly ordered)
- added virNodeDeviceObjListForEach() and virNodeDeviceObjListRemoveLocked()
to simplify removing devices that are removed from mdevctl.
- coding style fixes
- NOTE: per Erik's request, I experimented with changing the way that mdevctl
commands were generated and tested (e.g. introducing something like
virMdevctlGetCommand(def, MDEVCTL_COMMAND_<SUBCOMMAND>, ...)), but it was
too invasive and awkward and didn't seem worthwhile
Changes in v2:
- rebase to latest git master

[PATCH] build-aux: increase tests timeout
by Roman Bogorodskiy
Meson default timeout for test() is 30 seconds. This may be not enough
for some tests like sc_prohibit_nonreentrant or
sc_libvirt_unmarked_diagnostics, so set it to 60 seconds.
Signed-off-by: Roman Bogorodskiy <bogorodskiy(a)gmail.com>
---
On my system these two tests always timeout with the default value.
That's what I have after increasing timeout:
157/288 libvirt:syntax-check / sc_prohibit_nonreentrant OK 52.18s
183/288 libvirt:syntax-check / sc_libvirt_unmarked_diagnostics OK 31.48s

Release of libvirt-7.1.0
by Jiri Denemark
The 7.1.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at
https://libvirt.org/sources/
https://libvirt.org/sources/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing any other feedback. Your work is
greatly appreciated.
* Portability
* Implement Apple Silicon support
libvirt now runs on the ARM-based Apple Silicon Macs.
* New features
* Introduce virtio-pmem ``<memory/>`` model
The virtio-pmem is a virtio variant of NVDIMM and just like NVDIMM
virtio-pmem also allows accessing host pages bypassing guest page cache.
* Introduce ``<boot order/>`` for ``<filesystem>``
Booting is possible from virtiofs filesystems. Introduce an option
to control the boot order, like we do for other bootable devices.
* hyperv: implement new APIs
The ``virDomainUndefine()``, ``virDomainUndefineFlags()``,
``virDomainDefineXML()``, ``virDomainAttachDevice()``, and
``virDomainAttachDeviceFlags()``, ``virConnectListAllNetworks()``,
``virConnectNumOfNetworks()``, ``virNetworkLookupByName()``,
``virNetworkLookupByUUID()``, ``virConnectNumOfDefinedNetworks()``,
``virConnectListDefinedNetworks()``, ``virNetworkGetAutostart()``,
``virNetworkIsActive()``, ``virNetworkIsPersistent()``,
``virNetworkGetXMLDesc()``, and ``virDomainScreenshot()``, APIs have been
implemented in the Hyper-V driver.
* Support <teaming> element in plain <hostdev> devices
This is useful when libvirt doesn't have the privileges necessary
to set the hostdev device's MAC address (which is a necessary
part of the alternate <interface type='hostdev'>).
* Introduce ``<disk type='vhostuser'>`` support
Introduces support for QEMU vhost-user-blk device that can be used
to access storage exported via the vhost-user protocol by daemons such
as the ``qemu-storage-daemon``.
* Bug fixes
* qemu: Fix disk quiescing rollback when creating external snapshots
If the qemu guest agent call to freeze filesystems failed when creating
an external snapshot with ``VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE`` flag the
filesystems would be unconditionally thawed. This could cause problems when
the filesystems were frozen by an explicit call to ``virDomainFSFreeze``
since the guest agent then rejects any further freeze attempts once are
filesystems frozen, an explicit freeze followed by a quiesced snapshot
would fail and thaw filesystems.
Users are also encouraged to use ``virDomainFSFreeze/Thaw`` manually instead
of relying on ``VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE`` if they need finer
grained control.
* cgroups: Fix how we setup and configure cgroups on hosts with systemd
When libvirt is running on host with systemd we register every VM with
machined which creates the VM root cgroup for us as well. Before this fix
we were directly modifying files in the VM root cgroup which was incorrect
because all the files are managed by systemd. The implication was that any
change done by libvirt to cgroup attributes supported by systemd could be
removed which happens for example by running ``systemctl daemon-reload``.
To fix the issue libvirt now uses DBus calls for some of the cgroup
attributes that distribute the resources proportionally to the cgroup
siblings and for the rest we have a new sub-cgroup that libvirt can
managed directly.
For more details why this is necessary see
`systemd cgroup <https://systemd.io/CGROUP_DELEGATION/>`_ documentation.
* qemu: Fix swtpm device with aarch64
The TPM TIS device name for x86 is ``tpm-tis``, whereas for aarch64 it is
``tpm-tis-device``. Fix the use of TPM TIS device with aarch64 by using
the proper device name when building the QEMU command line.
* libxl: Fix domain shutdown
Commit fa30ee04a2 introduced the possibility of a race between the
shutdown and death threads used to process domain shutdown and death
events from libxl. On normal domain shutdown the shutdown thread handles
all aspects of shutting down and cleaning up the domain. The death
thread is only used to handle out-of-band domain destruction and is
inhibited when domain shutdown is under libvirt's control. The race is
avoided by also inhibiting the death thread when libvirt starts the
shutdown thread.
Enjoy.
