lxc container startup error and RFC patch
by Cole Robinson
Hi all,
I'm seeing LXC container startup failures. This is with libvirt git,
fedora 34 host with systemd-248.6-1.fc34.x86_64 (I didn't confirm with
other versions). Reproducer:
sudo virt-install --connect lxc:/// --name test-container --memory 128
--boot init=/bin/sh
Starting install...
ERROR error from service:
GDBus.Error:org.freedesktop.machine1.NoMachineForPID: PID 2145047 does
not belong to any known machine
libvirt 7.0.0 works but 7.1.0+ does not. The root error seems to predate
that, showing up in syslog, but commit 9c1693eff made it fatal:
commit 9c1693eff427661616ce1bd2795688f87288a412

vircgroup: use DBus call to systemd for some APIs
The error comes from virSystemdGetMachineByPID. The PID that shows up in
the above error message does not match the leader PID as reported by
machinectl. This change fixes the error but I don't know if it's correct
or if it has other implications:

Maybe something else isn't working elsewhere. Clearly we try to add both
pids to the systemd machine, but virSystemdGetMachineByPID is not
working to match the non-leader pid, which is the one that the LXC
driver knows about.
Thoughts?
Can anyone else reproduce?
Thanks,

Release of libvirt-7.6.0
by Jiri Denemark
The 7.6.0 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.
* Security
* storage: Unlock pool objects on ACL check failures in ``storagePoolLookupByTargetPath`` (CVE-2021-3667)
A logic bug in ``storagePoolLookupByTargetPath`` where the storage pool
object was left locked after a failure of the ACL check could potentially
deprive legitimate users access to a storage pool object by users who don't
have access.
* New features
* qemu: Incremental backup support via ``virDomainBackupBegin``
libvirt-7.6 along with the unreleased qemu-6.1 will fully support the change
block tracking features (block-dirty-bitmaps) to be able to do incremental
backups and management of the checkpoint states via the appropriate APIs.
* qemu: Add support for launch security type s390-pv
Specifying s390-pv as launch security type in an s390 domain prepares for
running the guest in protected virtualization secure mode, also known as
IBM Secure Execution. This simplifies the definition and reduces the risk
of an incorrect definition, e.g. by forgetting to specify ``iommu=on`` on
all virtio devices.
* domstats: Add haltpolling time statistic interface
Domstats now provide the data of cpu haltpolling time. This feature relies
on statistics available after kernel version 5.8. This will allow the user
to get more accurate CPU usage information if needed.
* Bug fixes
* qemu: Fix migration with ``VIR_MIGRATE_NON_SHARED_INC``
libvirt 7.3.0 introduced a bug where ``VIR_MIGRATE_NON_SHARED_INC`` would
not actually migrate the contents of the disk due to broken logic and at
the same time could trigger migration of storage when
``VIR_MIGRATE_TUNNELLED`` is requested. This release fixes the bug.
* qemu: Don't emit ``VIR_DOMAIN_EVENT_ID_BLOCK_THRESHOLD`` twice when registered with index
When registering the threshold event with the index notation (e.g.
``vda[3]``) libvirt would emit the event also for ``vda`` if the image is
in the top layer. The intention was to emit two events only when the
original registration was done without the index.
* qemu: Pass discard requests for disks with ``copy_on_read='on'``
When a disk using the ``copy_on_read='on'`` option is configured also with
``discard='unmap'`` the discard requests will now be passed to the
underlying image freeing up the space.
Enjoy.
