[vbox-dev] Setting linkstate using API?

[Karoline Haus]

No I'm pretty sure I'm getting the right machine object and the session is valid as well. I can change other properties.

Do I have to call saveSettings() after changing cableConnected, or will it have immediate effect without calling saveSettings()?

Thanks, Karoline

This means you're using the wrong Machine object, or completely lack the 
session handling... it works fundamentally the same way as if the VM 
isn't running: create a session, get a shared lock (an exclusive one 
isn't possible while the VM is running), and use the Machine reference 
associated with this session.

That one is writable.
