[PATCH] libvirt-guests: Fix dependency ordering in service file
by Martin Kletzander 26 Sep '22

26 Sep '22

After some debugging and discussion with systemd team it turns out we are misusing the ordering in libvirt-guests.service. That happened because we want to support both monolithic and modular daemon setups and on top of that we also want to support socket activation and services without socket activation. Unfortunately this is impossible to express in the unit file because of how transactions are handled in systemd when dependencies are resolved and multiple actions (jobs) are queued. For explanation from Michal Sekletar see comment #7 in the BZ this patch is fixing: https://bugzilla.redhat.com/show_bug.cgi?id=1964855#c7 In order to support all the scenarios this patch also amends the manpages so that users that are changing the default can also read how to correct the dependency ordering in libvirt-guests unit file. Ideally we would also keep the existing configuration during upgrade, but due to our huge support matrix this seems hardly feasible as it could introduce even more problems.

[libvirt PATCH] nodedev: switch to udev 'bind' events
by Jonathon Jongsma 24 Sep '22

24 Sep '22

Rather than listening to 'add' udev events, listen for 'bind' events instead. When we get an 'add' event, the sysfs tree for the device is often not ready yet. In that case we sleep in a loop until the sysfs tree appears, or give up after a timeout. udev added the 'bind' event to give userspace a signal that indicated when driver-specific attributes were available to be used. In other words, the sysfs tree *should* be ready and usable at this point. But just to be safe, we'll leave the wait loop in the code to handle corner cases, with the hope that it'll never be used. The udev 'bind' event was added in kernel 4.14 and the oldest platform we support has kernel 4.18, so it should be safe to make this change.
