qr-XXXXX is the internal router IP interface (as you correctly guessed, 
ie. 10.5.5.1) and bound to br-int.
tap-XXXX is the DHCP server IP interface (ie. 10.5.5.2), also bound to 
br-int.

'brctl show' gives you the output.

Could you please provide us "route -n" on the network node" ?
Could you also make sure (with 'ovs-vsctl show') that port 'qr-XXXX' and 
'tapXXXX' do have the same tag number as for VMs ? (should be tag:1)
