Actually, it is valid to call virDomainDefineXML() even for a domain which
is already running. This is critical to be able to implement provisioning
tools like virt-install - we first boot a domain with the config needed
to kick off the installer (eg explicit initrd/kernel, or ISO), and then
define a config file for subsequent boots (eg pygrub).  So, just killing
these 2 lines & the rest of the patch is OK.
