[pve-devel] [RFC manager] disable shutdown button when suspended

[Dominik Csapak]

since shutdown of a vm when it is suspended is not really nice,
(it hangs until we run in a timeout, then shuts down on resume)
we disable the button in this case.

since you cannot disable only the button portion of a splitbutton,
we do nothing on a click event and tone down the content, to
show that the button is disabled

this does not really look nice, because
it is not really clear why you cannot shutdown

would it be better to have a popup saying:
'you cannot shutdown when vm is paused'
or something like this?
