Hi,
I think that this variable is useful for me
cfg.IntOpt("reboot_timeout",
              default=0,
              help="Automatically hard reboot an instance if it has been "
                   "stuck in a rebooting state longer than N seconds. "
                   "Set to 0 to disable."),
   cfg.IntOpt("instance_build_timeout",

but it seems that Eli is right: lbvirt driver doesn't implement this 
function

def poll_rebooting_instances(self, timeout, instances):
pass



BTW I'm developing a feature: booting from network.
In my scenario sometimes the the booting instance pauses because the 
boot source ( PXE) cannot answer on time.
Look at
6.4. Installing guest virtual machines with PXE

I'll investigate on reboot_timeout and I'll inform you but thanks for 
the tips

BR
Angelo
