> According to a source file *site-packages/libcloud/compute/drivers/cloudstack.py*, 
> the *ex_list_projects()* receives strings from CloudStack and converts it into integers
with buit-in function *int()*. The built-in function *int()* can only accept strings which
represent integers (_e.g. '3', '-1'_). However CloudStack may return a string *'Unlimited'*,
which *int()* can not deal with.
> I modified the source file in order to treat _'Unlimited'_ as _-1_, then the error disappeared.
