The /var/lib/libvirt/qemu/save directory is not actually created by the installation of libvirt-bin, it is created by libvirt upon startup. So if libvirt is slow to initialize and this task runs before the directory is created, then the next task: "Check if the qemu save directory is empty" will fail with: stderr: ls: cannot access /var/lib/libvirt/qemu/save: No such file or directory Change-Id: I0d035fa6b4eaedebb733fef2126fe9c4f63c2917
