Cannot create a Linux template on SCVMM 2012 GA

HI,

I have installed SCVMM 2012 GA build.

I am facing issue while creating Linux template for RHEL 6.2.

after I created the VM using ISO and set the operating system accordingly, the create template menu option is disabled.

only clone to template option is enabled.

is Guest customization not supported for Linux VMs?

I can do the same with SCVMM 2012 Sp1 "BETA"

is there any workaround.

Thanks.
