Description of problem:
Version-Release number of selected component (if applicable):
RHEL6.4 host:
kernel2.6.32-348.el6.x86_64
qemu-kvm-0.12.1.2-2.346.el6.x86_64
RHEL6.3-z host:

2. On rhel6.3 host:
(qemu) info qtree
3. Boot the guest on rhel6.4 host with the same command line but append "-M rhel6.3.0"
4. On rhel6.4 host:
(qemu)info qtree
5. Compare the output on step 2 and step 4.
Actual results:
Lot's of properties are different, some properties showing up on 6.4 host but not on 6.3 host.
Some property values are changed on 6.4 host.
Here only highlight some of them, for detail please check attachment.
