[libvirt PATCH] docs: replace footer link to the bird site with mastodon
by Daniel P. Berrangé 14 Dec '22

14 Dec '22

Since the takeover of the bird site, the bulk of tech people who want a more friendly and inclusive media site have jumped over to Mastodon. With its decentralized nature, there's no one replacement that captures everything, but the fosstodon.org site is a topic relevant choice. Signed-off-by: Daniel P.

[PATCH 0/7] spec: Decompose the daemon subpackage
by Jim Fehlig 14 Dec '22

14 Dec '22

This is a V1 of my previous RFC to decompose the libvirt-daemon package https://listman.redhat.com/archives/libvir-list/2022-November/235924.html The end goal is to remove the libvirt-dameon dependency on the various libvirt-daemon-driver-foo subpackages, allowing installation of a modular daemon configuration without the traditional monolithic libvirtd. Change from V1: - Patches1-3 handled separate from this series since they are unrelated - virtlockd, virtlogd, and virtproxyd are moved to their own subpackages - lockd plugin moved to its own subpackage - virt-admin, virt-host-validate, and others moved to new subpackage TODO: The libvirt-daemon package still contains the following files, which likely need to move somewhere since they are needed by the modular daemons too. %{_unitdir}/virt-guest-shutdown.target I thought of moving this to the libs package, but that would be a change for installations with only libvirt-client. AFAICT, it's used by libvirt-guests and the qemu and lxc drivers. %config(noreplace) %{_sysconfdir}/sasl2/libvirt.conf Another file related to remote access. Should it go to libvirt-libs? %ghost %dir %{_rundir}/libvirt/ %ghost %dir %{_rundir}/libvirt/common/ %dir %attr(0755, root, root) %{_localstatedir}/lib/libvirt/ %dir %attr(0711, root, root) %{_localstatedir}/lib/libvirt/images/ %dir %attr(0711, root, root) %{_localstatedir}/lib/libvirt/filesystems/ %dir %attr(0711, root, root) %{_localstatedir}/lib/libvirt/boot/ %dir %attr(0711, root, root) %{_localstatedir}/cache/libvirt/ %dir %attr(0755, root, root) %{_libdir}/libvirt/ %dir %attr(0755, root, root) %{_libdir}/libvirt/connection-driver/ These files and directories are needed by the modular daemons as well, right?

[PATCH] qemu_process: add tray changed event to queue in refresh disks
by Kristina Hanicova 13 Dec '22

13 Dec '22

There are some cases when the internal state of disks can change without qemu sending events about it (e.g. a disk can close during reset). In case this happens, we should emit an event about the modified disk.

[libvirt PATCH v3 00/18] Use nbdkit for http/ftp/ssh network drives in libvirt
by Jonathon Jongsma 13 Dec '22

13 Dec '22

This is the third version of this patch series. See https://bugzilla.redhat.com/show_bug.cgi?id=2016527 for more information about the goal, but the summary is that RHEL does not want to ship the qemu storage plugins for curl and ssh. Handling them outside of the qemu process provides several advantages such as reduced attack surface and stability. A quick summary of the code: - at startup I query to see whether nbdkit exists on the host and if so, I query which plugins/filters are installed. These capabilities are cached and stored in the qemu driver - When the driver prepares the domain, we go through each disk source and determine whether the nbdkit capabilities allow us to support this disk via nbdkit, and if so, we allocate a qemuNbdkitProcess object and stash it in the private data of the virStorageSource. - The presence or absence of this qemuNbdkitProcess data then indicates whether this disk will be served to qemu indirectly via nbdkit or directly - When we launch the qemuProcess, as part of the "external device start" step, I launch a ndkit process for each disk that is supported by nbdkit. - for devices which are served by an intermediate ndkit process, I change the qemu commandline in the following ways: - I no longer pass auth/cookie secrets to qemu (those are handled by nbdkit) - I replace the actual network URL of the remote disk source with the path to the nbdkit unix socket - We create a 'monitor' for the nbdkit process that watches to see whether the process exits. If it does, we pause the domain, attempt to restart nbdkit, and then resume the domain. Open questions - I think selinux will work once we add a policy for the /usr/sbin/nbdkit binary to allow it to be executed by libvirt, but for now it fails to execute nbdkit in enforcing mode. The current context for nbdkit (on fedora) is "system_u:object_r:bin_t:s0". When I temporarily change the context to something like qemu_exec_t, I am able to start nbdkit and the domain launches. Known shortcomings - creating disks (in ssh) still isn't supported. Changes in v3: - Various formatting fixes - Don't kill process in qemuNbdkitProcessFree() since we want the nbdkit daemon to continue running even if libvirt restarts. - Better detection and error reporting when starting the nbdkit process - Add monitoring for nbdkit process so that it can be restarted if if ever exits unexpectedly. Changes in v2: - split into multiple patches - added a build option for nbdkit_moddir - don't instantiate any secret / cookie props for disks that are being served by nbdkit since we don't send secrets to qemu anymore - ensure that nbdkit processes are started/stopped for the entire backing chain - switch to virFileCache-based capabilities for nbdkit so that we don't need to requery every time - switch to using pipes for communicating sensitive data to nbdkit - use pidfile support built into virCommand rather than nbdkit's --pidfile argument - added significantly more tests Jonathon

[PATCH] meson: Provide default values for nonexistent xenlight pkgconfig vars
by Michal Privoznik 12 Dec '22

12 Dec '22

It may happen that xenlight pkgconfig file does not contain 'xenfirmwaredir' and/or 'libexec_bin' variables, which is okay and we have code that deals with this situation. But that code is executed when the queried value is an empty string. This may not always be the case and we should specifically set 'default_value' so that the empty string is returned if pkgconfig variable doesn't exist.
