AFAIK, you're doing the right thing (as long as you're doing a 
"dump-xml" to get the XML description out and then a "define" to put the 
updated one in; directly modifying /etc/libvirt/qemu/* is bad form).

Personally, I use xmlstarlet [from shell scripts] or lxml [from python] 
to automate tweaking the XML host descriptions, but the details are your 
own call.
