Because we made a mistake in some of our initial vCloud templates, many VMs have less than 1 GB of free disk space on C:. And since those were templates, many users inherited them (50+). For us it would be really helpful to define the threshold in MBs. Right now its turned off and we run in 0 bytes free. Adding more space automatically in vCloud to all those different vApps is cumbersome, and we are not yet quite there yet with or task manager.
