+Subject: [PATCH] set the cpuset.cpus/mems of machine.slice to all by default
+ This is necessary after merging core-cgroup-support-cpuset.patch.
+
+When creating a vm, libvirt will issue a dbus method_call to
+systemd-machined. systemd-machined will start transient unit
+usually named xxx.scope with Delegate=1 set after receiving
+the method_call. If Delegate=1 is set, systemd will create
+machine.slice in /sys/fs/cgroup for every cgroup subsystem, this
+includes cpuset. cpuset is different, you can't migrate processes
+to the created directory unless you have set proper cpuset.cpus
+and cpuset.mems.
+
+Without this patch, libvirt sees machine.slice, it won't check
+if cpuset.cpus or cpuset.mems is valid, and just migrate the vm
+process to machine.slice. This action will fail because core-cgroup
+-support-cpuset.patch only supports create the machine.slice
+directory when Delegate=1 is set, but won't set cpuset.cpus
+and cpuset.mems automatically.
+
+Now we have this patch, it will make systemd automatically set
+cpuset.cpus and cpuset.mems according to /sys/fs/cgroup/cpuset/{
+cpuset.cpus, cpuset.mems}. Then libvirt can migrate vm processes
+freely.
