+Subject: [PATCH] Do not log rotate very small logs
+
+Without this, after few weeks without use, each defined domain grows a
+tail of empty gzipped logs, instead of keeping just the last log of
+interest.
+
+* daemon/libvirtd.logrotate.in: only rotate when the log is over 100 KBytes

+Subject: [PATCH] Fix save and restore with non-privileged guests and SELinux
+
+When running qemu:///system instance, libvirtd runs as root,
+but QEMU may optionally be configured to run non-root. When
+then saving a guest to a state file, the file is initially
+created as root, and thus QEMU cannot write to it. It is also
+missing labelling required to allow access via SELinux.
+
+* src/qemu/qemu_driver.c: Set ownership on save image before
+  running migrate command in virDomainSave impl. Call out to
+  security driver to set save image labelling
+* src/security/security_driver.h: Add driver APIs for setting
+  and restoring saved state file labelling
+* src/security/security_selinux.c: Implement saved state file
+  labelling for SELinux
+
