But the case that Stephan has where libvirtd does create the directories
on startup is broken. I've ran into this problem myself, but forgot
about it until now, when running libvirtd from the source tree with
prefix /usr/local.

It seems that when creating the directories in the driver
initialization, at least the QEMU driver does not set the umask
accordingly before, manginling the resulting permissions in the process.
