Mea-culpa I forgot to push RC2 on Tuesday, rather than pushing the release off by 2 more days, I decided to push the release today to stay on schedule. As a result 6.2.0 is out, tagged in git and source tarball and rpm are available at the usual place: https://libvirt.org/sources/ I also pushed a release of the python binding with minimal changes that can be found at: https://libvirt.org/sources/libvirt/ New features: - qemu: NVDIMM support for pSeries guests QEMU 5.0 implements NVDIMM memory support for pSeries guests. This is done by adding an 'uuid' element in the memory XML, which can either be provided in the XML or, if omitted, generated automatically. - qemu: Add virtiofs support This feature, introduced in QEMU 4.2, is a more modern alternative to virtio-9p, which is exposed through the same <filesystem/> element. - admin: Support reloading TLS certificates After renewing TLS certificates, it was usually necessary to restart libvirtd for the new ones to be loaded: now the same result can be obtained without restarting the daemon by using virt-admin server-update-tls. Removed features: - Removed support for INI style of comments With switching of our internal code to GLib, parsing of client authentication config files is handed over to GLib which does not support INI style of comments starting with a semicolon (;). Use number sign (#) instead. * Improvements - qemu: Don't compare local and remote hostnames on migration This check was introduced to prevent same-host migration, but did not work as expected when multiple libvirtd instances were running on the same host but in different containers. With this release, the host UUID (which should be unique to the container) is checked instead. - qemu: Use per-VM event loops Instead of using a single even loop to process communication with the QEMU monitor and guest agent, create a separate one for each VM. This helps with scalability and prevents scenarios where a single malfunctioning VM could affect all those running on the same host. - qemu: Support migration with SLIRP helper interface With QEMU 5.0, a new D-Bus backend allows migration of external processes. When needed, libvirt will start a per-vm D-Bus bus, and migrate the slirp-helper along with QEMU. Bug fixes: - qemu: Open backing chain late for shallow block copy reusing external images With introduction of -blockdev for QEMU storage configuration in libvirt-5.10 we've started opening the backing chain of the destination/mirror of a virDomainBlockcopy started with VIR_DOMAIN_BLOCK_COPY_REUSE_EXT | VIR_DOMAIN_BLOCK_COPY_SHALLOW flags when starting the job rather than when virDomainBlockJobAbort with VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT is issued. For users depending on this undocumented quirky pre-blockdev behaviour this caused a regression as the backing chain could not be modified while the copy of the top image was progressing due to QEMU image locking. Note that this fix also requires qemu-5.0 while -blockdev is used starting from QEMU-4.2. - Don't generate machine names containing dots Even though the guest name containing dots is not a problem for libvirt itself, we need to strip them out when registering with machined because of the latter's requirements. Thanks everybody who contributed to this release be it with bug reports, fixes, reviews, documentation, etc ... Enjoy the release, stay safe!
