It HAD one. They fixed it.
I think the same security problem will also bite you if you implement it 
manually using home-made script :)

Yeah, that's the thing. Weird, considering it's the default bootloader 
when installed using virt-manager/virt-install.
Try here

http://www.centos.org/docs/5/html/5.2/Virtualization/sect-Virtualization-Installing_guests-Create_a_guest_using_virt_manager.html

In short, if your domU has kernel, initrd, and grub config on it (as is 
the case when installed with virt-manager), you can boot it with pygrub.
