If I correctly understand what you mean, then that is the current
"intended" behavior - supplying NICs as part of VM creation isn't
supported, and there's this RFE to support it:
https://bugzilla.redhat.com/show_bug.cgi?id=999969

My two original suggestions will apparently have to suffice until this
RFE is realised; either properly configuring the template's NICs before
VM creation or modifying the VMs' NICs following creation.
