[libvirt] [PATCH] daemon: improve Xen support in systemd service
by Jim Fehlig
The xencommons service provides all the essential services such as
xenstored, xenconsoled, etc. needed by the libvirt Xen driver, so
libvirtd should be started after xencommons.
The xendomains service uses Xen's xl tool to operate on any domains it
finds running, even those managed by libvirt. Add a conflicts on the
xendomains service to ensure it is not enabled when libvirtd is enabled.

[libvirt] [PATCH] tools: console: Use proper constructor
by Roman Bolshakov
"virsh console" on macOS cannot attach to a domain and it doesn't matter if
it's local or remote domain:
$ ~ virsh console vm
Connected to domain vm
Escape character is ^]
error: internal error: unable to wait on console condition
The error comes from pthread_cond_wait that fails with EINVAL. The mutex
in the parent is not initialized with pthread_mutex_init and it results
in silent failure of pthead_mutex_lock and the attach failure.

[libvirt] [PATCH] news.xml: Restore blank news example
by Michal Privoznik
In v5.6.0-rc1~347 I've mistakenly messed up news.xml as the
change I wanted to promote was added into a comment (I blame git
rebase for that). Anyway, restore the original state of the
comment so it can be copied again.

[libvirt] Release of libvirt-5.6.0
by Daniel Veillard
It's out ! Tagged in git and with signed tarball and source rpm at the usual
place:
https://libvirt.org/sources/
I also released the 5.6.0 python bindings for the release that can be found
at:
https://libvirt.org/sources/python/
This release includes a number of new features, notably the checkpoint APIs
removes the sxpr xen support and carries a set of improvement and bug fixes
as usual:
New features:
- qemu: Introduce a new video model of type 'bochs'
Introduce a new video model type that supports the bochs-display device
that was added in qemu version 3.0.
- api: new virDomainCheckpoint APIs
Introduce several new APIs for creating and managing checkpoints in the
test and qemu drivers (the latter requires qcow2 images). Checkpoints
serve as a way to tell which portions of a disk have changed since a
point in time.
- qemu: Add support for overriding max threads per process limit
systemd-based systems impose a limit on the number of threads a process
can spawn, which in some cases can be exceeded by QEMU processes
running VMs. Add a max_threads_per_process option to qemu.conf to
override the system default.
- Remember original owners and SELinux labels of files
When a domain is starting up libvirt changes DAC and SELinux labels so
that domain can access it. However, it never remembered the original
labels and therefore the file was returned back to root:root. With this
release, the original labels are remembered and restored properly.
- network: Allow passing arbitrary options to dnsmasq
This works similarly to the existing support for passing arbitary
options to QEMU, and just like that feature it comes with no support
guarantees.
Removed features:
- xen: Remove sxpr config support
Remove the sxpr style config parser and formatter a year after the xend
driver was removed.
Improvements:
- qemu: Allow XML validation for snapshot creation
Add flag VIR_DOMAIN_SNAPSHOT_CREATE_VALIDATE to validate snapshot input
XML. For virsh, users can use it as virsh snapshot-create --validate.
- Support encrypted soft TPM
A soft TPM backend could be encrypted with passphrase. Now libvirt
supports using a secret object to hold the passphrase, and referring to
it via the encryption element of the TPM device.
- test driver: Expand API coverage
Additional APIs have been implemented in the test driver.
- Implement per-driver locking
Drivers now acquire a lock when they're loaded, ensuring that there can
never be two instances of the same driver active at a time.
- nss: Report newer addresses first
In some cases, a guest might be assigned a new IP address by DHCP
before the previous lease has expired, in which case the NSS plugin
will correctly report both addresses; many applications, however,
ignore all addresses but the first, and may thus end up trying to
connect using a stale address. To prevent that from happening, the NSS
plugin will now always report the newest address first.
- util: Optimize mass closing of FDs when spawning child processes
When the limit on the number of FDs is very high, closing all unwanted
FDs after calling fork() can take a lot of time and delay the start of
the child process. libvirt will now use an optimized algorithm that
minimizes such delays.
Bug fixes:
- logging: Ensure virtlogd rollover takes priority over logrotate
virtlogd implements its own rollover mechanism, but until now logrotate
could end up acting on the logs before virtlogd had a chance to do so
itself.
Thanks everybody who helped with this release, be it with bug reports,
patches, reviews, documenation, localization, etc ...
Enjoy the release,
Daniel
