[RFC 0/1] virxml: Accept 'default' for virTristate* properties
by Andrea Bolognani 24 Mar '22

24 Mar '22

Sending this as an RFC because it's incomplete. After virXMLPropTristate*() had been introduced, existing code was gradually converted to use the new helpers; however, if you look for example at 593140dabd66 you'll see that the original implementation considered encountering 'default' to be an error, and the change I'm proposing would relax such a check. So we need to go through the callers one by one, adapting them as necessary (in this case, we would pass VIR_XML_PROP_NONZERO in addition to existing flags) to ensure that the original semantic is preserved. Any better ideas? Andrea Bolognani (1): virxml: Accept 'default' for virTristate* properties src/util/virxml.c | 4 ---- 1 file changed, 4 deletions(-) -- 2.35.1

[libvirt PATCH 0/3] Enable copy/paste for vnc displays
by Jonathon Jongsma 23 Mar '22

23 Mar '22

This patch series enables support for the qemu-vdagent character device which enables copy/paste support between guest and client when using vnc graphics. The guest must be configured with something like the following: <channel type='qemu-vdagent'> <source clipboard='on' mouse='on'/> <target type='virtio' name='com.redhat.spice.0'/> </channel> Copy/paste sync requires a vnc client that has support for copy/paste commands. Currently virt-viewer does not work, but the version of tigervnc provided by fedora (executable name 'vncviewer') does work. More details about this device on Gerd's blog: https://www.kraxel.org/blog/2021/05/qemu-cut-paste/ OPEN QUESTIONS: - I'm not fully convinced that the `<source>` element is the right place for the new `clipboard` / `mouse` configuration options, but I'm not sure that adding a new xml element to the `<channel>` is the right approach either. Suggestions welcome. - There may be an expectation that vnc clipboard is enabled using the <graphics type='vnc'><clipboard copypaste='yes'/></graphics> similar to what spice offers. In fact, it seems that this is the approach Marc-Andre took when adding copy/paste support in his dbus display patch series. But even for spice, this <clipboard> configuration element is not enough to enable the copy/paste feature. It also requires a 'spicevmc' character device to be added to the domain.

[libvirt PATCH] ci: integration: Rename all Avocado standard stream log files to *.log
by Erik Skultety 22 Mar '22

22 Mar '22

By default, stdout/stderr Avocado test log files do not have any file extension which confuses GitLab's web UI to mangle the MIME type for these and so the browser will never offer the option to open such file from in a text editor rather than dowloading it. Since GitLab sets a proper MIME for .txt and .log file extensions, rename all Avocado log files without an extension to *.log . This pairs nicely with the coredumpctl info file which we already name as 'coredumpctl.txt' because of this.

[libvirt PATCH 0/2] [CI] Fix running integration pipeline in forks + collect daemon stack trace
by Erik Skultety 22 Mar '22

22 Mar '22

Even if users set the LIBVIRT_CI_INTEGRATION variable to 1 to enable the integration test suite with their own private runner, the pipeline will be stuck because we expect the runner to have the 'redhat-vm-host' tag. We need to define the job tag dynamically instead, so that the users can set the variable for their libvirt fork to match one of their runner's tags. A recent crash in libvirt showed us that we also need to collect stack traces as well, so this series also takes care of setting up systemd to be able to collect them on failed jobs. Both fixes are demoed with pipeline [1]. Note that for the pipeline I reverted 17fe6a090ba389cdd228c3e176788d9b2d45525f just to demonstrate the stack trace collection on a crash.

[PATCH] gitpublish: Drop "libvirt" from prefix
