[Bug 495394] Re: autostart almost always fails on boot time host

[Serge Hallyn]

@Franck78,

Thanks for the info.

Yes, slow storage is not addressed by this and also needs to be fixed.
For that one, I want to discuss with upstream, as we'll probably want to
use a generic tool to enumerate all the storage needed by autostart
domains.  Considering the many complicated possibilities, it seems a
daunting task.

I suppose a simple, non-intelligent way to go about it would be to grab
all 'source file=' and 'source dev=' lines inside a <disk > .. </disk>
stanza, and, in a /etc/init/libvirt-storage-waiter.conf, which is

  start on mounted and not started libvirt-bin

do something like

pre-start script
   if [ status libvirt-bin | grep start > /dev/null ]; then
      stop
      exit 0
   fi
   for f in `/sbin/enumerate-libvirt-autostart-files`; do
      if [ ! -r $f ]; then
         stop
         exit 0
      fi
   done
   initctl emit -n libvirt-storage-ready
end script

and have /etc/init/libvirt-bin.conf
   start on (runlevel [2345] and stopped networking STATUS=ok and libvirt-storage-ready)
