[PATCH 0/4] support for virtio packed virtqueues
by Bjoern Walk 03 Apr '20

03 Apr '20

QEMU recently (86044b24e) introduced packed virtqueues for virtio that supposedly have better cache utilization and performance compared to the default split queues. So here's a patch set that expose the virtio parameter as a optional libvirt XML attribute to virtio-backed devices, e.g.: <interface type='user'> <mac address='00:11:22:33:44:55'/> <model type='virtio'/> <driver packed='on'/> </interface> The default value if the attribute is omitted is still 'off' and regular split virtqueues are used.

[PATCH 00/15] move validations out of qemu_domain.c
by Daniel Henrique Barboza 03 Apr '20

03 Apr '20

This is a suggestion made by Peter in [1], in the review discussion of a series in which I started moving qemuCaps validation from qemu_command.c to qemu_domain.c [2]. I'll quote here what he said back then: "My only suggestion is that after this we should move all validation into a separate file. qemu_domain was a code dumping place for a long time and since we now have a lot of common code moving it out would be benficial for cleaning up an making it more obvious." This is my first go at it with a new file called 'qemu_validate.c'. The code changes are trivial - just moving stuff from qemu_domain to qemu_validate - but the amount of changes can sure make for really tedious reviews. Patches were split according to my own criteria of how annoying would it be to review each one. The maintainer is, as always, welcome to squash them up as necessary. There are still validations to be moved inside qemu_domain.c after this series. I chose to do this first round to validate the idea instead of rocking a 40-something patch series all of a sudden. Once this is figured out we can proceed with the moving. After all this is settled I intend to continue the work I started in [2], but using qemu_validate.c instead of qemu_domain.c as destination.

[libvirt-jenkins-ci PATCH] lcitool: Fix $PYTHON value in environment
by Andrea Bolognani 03 Apr '20

03 Apr '20

Starting with commit commit d76f41ece09b9aaf492553fe466c30a22c78e509 Author: Andrea Bolognani <abologna(a)redhat.com> Date: Fri Mar 27 17:21:26 2020 +0100 lcitool: Include paths in the inventory Figuring them out at runtime is neat, but in practice they don't change frequently enough for it to be necessary; more importantly, including them in the inventory means we can use them in the Dockerfile generator in addition to the Ansible playbooks. Signed-off-by: Andrea Bolognani <abologna(a)redhat.com> Reviewed-by: Daniel P. Berrangé <berrange(a)redhat.com> we have hardcoded the path of the Python interpreter to be used for builds in the inventory; an unforeseen consequence of this change is that Python builds on CentOS 7 have started failing. The reason for that is simple, but not immediately obvious. While on most target platforms we have a single Python interpreter installed, on CentOS 7 we still need two: Python 3 works fine when it comes to building projects, but it's missing a bunch of modules that Ansible needs to run, so we're stuck with Python 2 for Ansible use. This has worked fine for us so far. As part of the change above, however, due to a naming clash we have ended up in a situation where the bootstrap task, which installs a Python suitable for Ansible, overrides the Python intended for builds as set in the inventory. Of course this would result in breakages only on CentOS 7, where the two Pythons differ. Fix this by removing the runtime detection from the bootstrap task and storing the relevant information in the inventory.

Release of libvirt-6.2.0
by Daniel Veillard 02 Apr '20

02 Apr '20

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!

Can we just stop generating them? And get rid of all the existing ones, especially silly stuff like the binary RPMs from 2013 targeting Fedora 17. This will have the additional benefit of making it easier to find what you're looking for, since it will no longer be hidden among a heap of irrelevant garbage. > The source tarballs (eg libvirt-5.9.0.tar.xz) contain a spec file > inside. > > This means you can generate RPMs for your precise distro using something > akin to the following commands: > > $ rpmbuild -ts libvirt-5.9.0.tar.xz > $ sudo dnf install redhat-rpm-config > $ sudo dnf builddep $HOME/rpmbuild/SRPMS/libvirt-5.9.0-1.fc31.src.rpm > $ rpmbuild --rebuild $HOME/rpmbuild/SRPMS/libvirt-5.9.0-1.fc31.src.rpm I think it would make sense to document this quick procedure somewhere, if we haven't already. There's some obvious overlap with our 'make rpm' target, but that one requires unpacking the release archive and running configure beforehand, so it's not quite as nice for someone who just wants to quickly get a working set of RPMs. -- Andrea Bolognani / Red Hat / Virtualization
