Because using qemu-ga can change the state behind libvirt's back. So far
we've ignored tainted flag but the idea is to be similar to kernel and
its tainting.

In this specific case - libvirt offers a this particular command as an API:

libvirt_domain_interface_addresses() in PHP, or
virDomainInterfaceAddresses() in C.
