Description of problem: If there is a network interface on a host without any IP address and it's placed before the interface used for graphics device libvirtd will crash: Thread 1 (Thread 0x7f194b99d700 (LWP 5631)): 0 virNetDevGetifaddrsAddress (addr=0x7f194b99c7c0, ifname=0x7f193400e2b0 "ovirtmgmt") at util/virnetdevip.c:738 1 virNetDevIPAddrGet (ifname=0x7f193400e2b0 "ovirtmgmt", addr=addr@entry=0x7f194b99c7c0) at util/virnetdevip.c:795 2 0x00007f19467800d6 in networkGetNetworkAddress (netname=<optimized out>, netaddr=netaddr@entry=0x7f1924013f18) at network/bridge_driver.c:4780 3 0x00007f193e43a33c in qemuProcessGraphicsSetupNetworkAddress (listenAddr=0x7f19340f7650 "127.0.0.1", glisten=0x7f1924013f10) at qemu/qemu_process.c:4062 4 qemuProcessGraphicsSetupListen (vm=<optimized out>, graphics=0x7f1924014f10, cfg=0x7f1934119f00) at qemu/qemu_process.c:4133 5 qemuProcessSetupGraphics (flags=17, vm=0x7f19240155d0, driver=0x7f193411f1d0) at qemu/qemu_process.c:4196 6 qemuProcessPrepareDomain (conn=conn@entry=0x7f192c00ab50, driver=driver@entry=0x7f193411f1d0, vm=vm@entry=0x7f19240155d0, flags=flags@entry=17) at qemu/qemu_process.c:4969 7 0x00007f193e4417c0 in qemuProcessStart (conn=conn@entry=0x7f192c00ab50, driver=driver@entry=0x7f193411f1d0,vm=0x7f19240155d0,asyncJob=asyncJob@entry=QEMU_ASYNC_JOB_START, migrateFrom=migrateFrom@entry=0x0, migrateFd=migrateFd@entry=-1,migratePath=migratePath@entry=0x0,snapshot=snapshot@entry=0x0, vmop=vmop@entry=VIR_NETDEV_VPORT_PROFILE_OP_CREATE, flags=17, flags@entry=1) at qemu/qemu_process.c:5553 Version-Release number of selected component (if applicable): libvirt-daemon-2.0.0-10.el7_3.5.x86_64 Steps to Reproduce: 1. Create a new tun0 interface without any IP address $ ip tuntap add mode tun dev tun0 2. Create a new testbr bridge interface $ brctl addbr testbr 3. Define and start new network in libvirt $ cat testbr.xml <network> <name>testbr</name> <forward mode='bridge'/> <bridge name='testbr'/> </network> $ virsh net-define testbr.xml $ virsh net-start testbr.xml 4. Create a new guest with this graphics configuration: ... <graphics type='spice' autoport='yes'> <listen type='network' network='testbr'/> </graphics> 5. Start the guest $ virsh start GUEST_NAME
