[ovirt-devel] Memory size (1024MB) cannot exceed maximum memory size (0MB).] - when trying to create an instance type

While trying to add an instance type, I fail with the error: Operation Failed". Fault detail is "[Cannot add Template. Memory size (1024MB) cannot exceed maximum memory size (0MB).] The code is taken from the example in the SDK, so I'm not sure what I'm doing wrong here.
