[CentOS] KVM upgrade to 6.3

Hello,

I upgraded my centos 6.2 machine (KVM virtualization host) to 6.3.

Do I need to upgrade my virtual machine config files?

Result: /etc/libvirt/qemu/*.xml

<type arch='x86_64' machine='rhel6.2.0'>hvm</type>

Expected result:

<type arch='x86_64' machine='rhel6.3.0'>hvm</type>
