Forgot to add the output of the equivalent virsh command for the same 
VM:

 Name MAC address Protocol Address
-------------------------------------------------------------------------------
 lo 00:00:00:00:00:00 ipv4 127.0.0.1/8
 lo 00:00:00:00:00:00 ipv6 ::1/128
 eth0 52:54:00:12:b9:22 ipv4 192.168.7.31/26
 eth0 52:54:00:12:b9:22 ipv6 fe80::5054:ff:fe12:b922/64
 eth1 52:54:00:8e:b0:35 ipv4 192.168.1.34/24
 eth1 52:54:00:8e:b0:35 ipv6 fe80::5054:ff:fe8e:b035/64


Thanks,

Fernando
