From all the said above seems that indeed default shut-down time should be 0 But we need to be able to set shut-down policy per VM/Cluster/Something that will override the global config. One time fits all does not sound reasonable. I would say that for Desktop use case you'll probably want to allow the User some time to finish up things, while for Server you won't care.

So this shutdown grace period really depend if there are users connected to the VM or not. The question is how to easily distinguish - maybe depend on a spice session connection? That may be too heuristic.

[Users] forced shutdown with client agent
I have run into a scenario after installing the client agent. If a VM is shutdown, the client agent calls the shutdown command with a 1 minute timeout. Dummy-2::INFO::2013-03-28 14:05:21,892::vdsAgentLogic::138::root::Shutting down (timeout = 30, message = 'System Administrator has initiated shutdown of this Virtual Machine. Virtual Machine is shutting down.' Since the shutdown command is called with time parameter the VM sets the /etc/nologin file. When the VM is forced down the /etc/nologin file is not cleared and when it comes back up only root can login until the /etc/nologin file is cleared. Is their some some reason the shutdown time is set to 30 seconds (rounded up to 1 minute in the code)? Are there any know issues with setting this to 0? Is this the right way to change it to 0? psql engine postgres -c "update vdc_options set option_value = '0' where option_name = 'VmGracefulShutdownTimeout';" ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
