Simple response - you can't.
If you absolutely need the IVS functionality, Juniper would recommend that you go to their "virtual appliance" product and run all the images you need on a VMWare server.
Otherwise, you figure out how to simplify your current configuration to avoid IVSs. I think that is the route I'm taking.
You can complain to your sales rep or reseller, but I haven't seen any real value in that.
