That code is too unstable, so we disable that for now.

We should implement the fielset option in InputPanel instead (if we really want to use fieldsets)

And disable Floppy option (till now we do not support floppies)

We use this to lock OpenVZ containers.

Allow '-' in host names.

because this makes still problems with the scrollbar

and cleanup code

And try to disable upload when there are local modifications.

Also depend on redhat-cluster-pve

because the service is called /etc/init.d/cman (although the
binary running is corosync)
