The referenced commit is from 2005. I would not lose sleep over libvirt
not working with a ten year old kernel.

But the libvirt code using Processor was added by commit 347081e [1]
in 2013. Looks like the relevant kernel commit here is b4b8f770e [2]
from 2012. After that the model name is printed under 'model name',
not 'Processor:', so I'd expect your patch to break the test case added
by [1].

Adding a new test case is very welcome.
