That method only works for lxc (only the IP address of the *host* side 
of the tap device can be configured for qemu guests), and only if your 
libvirt is at least version 1.2.12.

Another method is to add a static host entry to the dhcp configuration 
for the network used to connect the guest. If the guest interface is 
connected to a libvirt virtual network, you can just do what is 
described here:

Otherwise, if the guest is connected via a bridge (or macvtap) directly 
to an external network, you'll need to configure the dhcp server for 
that network (which is outside the scope of libvirt)
