[one-users] How use all cpu flags with KVM (-cpu host)

Using *cat /proc/cpuinfo* on KVM virtual machines, appears the following
result for model name: QEMU Virtual CPU.
It is possible to use the argument *-cpu host* to force KVM using all cpu
Then, using *cat /proc/cpuinfo* appears the real cpu: Intel(R) Core(TM) i7
CPU 930 @ 2.80GHz with all its flags.
I would like to know if there is any way to setting up this at VM's template
or direct at deployment xml.
I am able to use just by command line: "kvm -cpu host ....".
I know it can mess up the live migration, but I would like to test.
Thanks a lot
