Reopen this bug ,

I still think we need use -M rhel5.6.0 as default on rhel5.6.0+ hosts.

That's wrong. We do not change the default on minor releases.
Anyone wishes to use another machine type should just use the right flag.

Reopen this bug .based on following reasons 

1.We hit lots of timer device issues if we forgot to add -M rhel5.6.0
2.qemu-kvm in RHEL6.x always change the default machine type to the newest one

That's a bug actually. Now is too late to fix
