[one-users] Migration problem

How can I change the machine type from the default of rhel5.4.0 to pc from 
within the VM template?

if I add to the vm template:
OS = [ ARCH = "x86_64", MACHINE = "pc" ]

and even though onevm show reveals:
OS=[
  ARCH=x86_64,
  MACHINE=pc ]

deployment.0 still only shows:
<type arch='x86_64'>hvm</type>

as opposed to the expected:
<type arch='x86_64' machine='pc'>hvm</type>
