Interesting... I'm on a server without configured sound system, so I'll check if thtat's related.

comment Impossible to log out from OpenSuSE's KDE menu
It's simple: Clicking on the "logout" menu entry does not do anything except dismiss the launcher. There are no processes started, no log entries, nothing. I am both asking for ways how to diagnose this (I imagine there might be a way to make KDE's event handlers write more verbose info to the logs or something similar) and how to remedy the problem.

OK, while I think I'll settle for a management wrapper in practice, +50 to you for pointing to the initscript!

Thanks for your reply and welcome to unix.stackexchange.com! However, I'm afraid your answer also does not address my issue: acpipowerbutton simulates pressing the power button on a real machine, but after issuing this command on the host, the VM would, again, take some time to shut down.

Basically, this would work, the appliance can be reached in the entire LAN via its DNS entry. However, suppose I wrote a script that ssh'd into the appliance whenever the host goes down -- it would still have to block (pause) until the guest has shut down completely. This is precisely the point of my question: How can the script know when the guest is down, so that it can yield control flow back to SysV-Init and the host can continue to shut down?

Thanks for your reply, but unfortunately, this does not address my issue: I need to gracefully shut down the guest, i.e. issue a "shutdown -h now" inside the guest and have the host wait until the guest has shut down completely. None of the VBoxManage controlvm subcommands do that.

Thanks for the suggestion. This did, however, not change the situation.
