Here is an example install which showed the problem. It is very similar 
to how I do all my EL6/EL7 installs (save for sometimes installing from 
PXE/http):

virt-install --connect qemu:///system \
   --name an-a03n01 \
   --ram 2048 \
   --arch x86_64 \
   --vcpus 2 \
   --cdrom /mnt/usb/VMs/files/CentOS-7.0-1406-x86_64-Everything.iso \
   --os-variant rhel7 \
   --network bridge=virbr0,model=virtio \
   --network bridge=virbr0,model=virtio \
   --network bridge=virbr0,model=virtio \
   --network bridge=virbr0,model=virtio \
   --network bridge=virbr0,model=virtio \
   --network bridge=virbr0,model=virtio \
   --disk path=/mnt/usb/VMs/images/an-a03n01.img,bus=virtio,size=40 \
   --graphics vnc

Note that the XML definition is properly updated (ie: boots of disk 
instead of CDROM in the above example). The above was run on a Fedora 20 
x86_64 host.

Please also note that, in this case, I created six NICs but I've seen 
this happen with just one defined (which is actually the majority of 
installs... this is a special case).

Here are the install logs:
