I think that for virtual machines it has a default value so that it isn't necessary to explicitly provide it. It may not have a default value fro instance types. Can you try adding this to the request to create the instance type? > > memory_policy=types.MemoryPolicy( > max=1 * 2**30 > ) > > Then try again. If it works I think that we need to fix the engine so that it assigns a default value, like it does for virtual machines.

The default for VMs comes from the Blank template. There’s no template for instance types, so it always needs to be provided > _______________________________________________ > Devel mailing list > Devel(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/devel > >
