Unless you specify a bridge in the xen conf file, it uses the first one it finds alphabetically, I believe. Do you use virbr0 for anything else? As an easy way of making sure xenbr0 is used, I removed the file /etc/libvirt/qemu/networks/autostart/default.xml which was auto-starting this DHCP (and NATted?) bridge, and I only was using direct access. But you can also make it explicit on the interface line, one of my HVM VMs has the following:
vif = [ 'mac=00:16:3e:0a:4c:d2, bridge=xenbr0' ]
