[libvirt] [dbus PATCH v3 1/5] introduce support for GDBus implementation
Pavel Hrdina
phrdina at redhat.com
Wed Mar 21 10:02:43 UTC 2018
We will switch to GDBus implementation of D-Bus protocol because
sd-bus implementation is not thread safe.
Processing messages in threads is essential since Libvirt API can
take some significant amount of time to return and that would block
the whole libvirt-dbus daemon.

Changes in v3:
- fixed a bug while loading XML interface files, now it fails
gracefully with error message
Changes in v2:
- changed glib2 required version to 2.44.0, required for the
auto-cleanup macros
- changed libvirt-glib required version to 0.0.7
