Multi-Machine Blueprint unable to select 0

Hello,

We have create a few Virtual machine Blueprints (sample below) per Operating system.

Windows Server 2008 R2 Database SQL 2008 R2

Windows Server 2008 R2 Database SQL 2012

Windows Server 2008 R2 Terminal Service

Windows Server 2008 R2 Domain Server (no dcpromo launched)

Windows Server 2008 R2

then created a Multi-Machine Blueprint for the Wndows Server 2008 R2 that includes these Virtual Machines.

What we would like is that the end user can select from the Self-Service Portal the Windows Server 2008 R2 he/she wants an increment to 1. Unfortunately, it looks like the value for Multi-Machine cannot be set to 0, but only 1, is this a bug or has someone found a fix ?

Thanks,

Erik
