In some cases the VM could no longer start when the timeout value was
set and afterwards, for example, hibernated. In this case the VM is
arguably soft locked, because the API would not allow changing the
timeout value anymore. (The only way out here would be to change the
value manually in the config)
To avoid unwanted side effects, it is possible to change the value for
the new 'startoptions' parameter, only if the VM is currently locked
with lock 'suspended'.
