   Well, I did try brctl and got a little farther than with ip.  I tried the   
   steps for ip listed in this website:   
      
   https://alberand.github.io/host-only-networking-set-up-for-qemu-hypervisor.html   
      
   Got all the way to this one before I got an error:   
      
   sudo dnsmasq --interface=br0 --bind-interfaces --dhcp-range=192.   
   68.0.3,192.168.   
      
   dnsmasq: failed to create listening socket for 192.168.0.17: Cannot assign   
   reque   
      
   However I think the issue might be right before that:   
      
   sudo ip link set dev br0 up   
   sudo ip link set dev tap0 up   
      
   These did not return any eror messages, but when I run ip addr, it tells me   
   that both br0 and tap0 are "state DOWN"?  I think they should be UP, right??   
      
   FYI, here is what ip addr returns:   
      
   1: lo:  mtu 65536 qdisc noqueue state UNKNOWN group   
   defaul   
       link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00   
       inet 127.0.0.1/8 scope host lo   
          valid_lft forever preferred_lft forever   
       inet6 ::1/128 scope host

   3: tap0:  mtu 1500 qdisc pfifo_fast master   
   br   
       link/ether 06:fc:5e:fd:6d:bb brd ff:ff:ff:ff:ff:ff   
   4: br0:  mtu 1500 qdisc noqueue state DOWN   
   gr   
       link/ether 06:fc:5e:fd:6d:bb brd ff:ff:ff:ff:ff:ff   
       inet 192.168.0.0/24 brd 192.168.0.255 scope global br0   
          valid_lft forever preferred_lft forever   
       inet 192.168.0.17/24 brd 192.168.0.255 scope global secondary br0   
          valid_lft forever preferred_lft forever   
       inet 192.168.0.11/24 brd 192.168.0.255 scope global secondary br0   
          valid_lft forever preferred_lft forever   
      
   For good measure, here is what my interfaces file looks like:   
      
   /etc/network/interfaces   
      
   auto br0   
   iface br0 inet dhcp   
      pre-up ip tuntap add dev tap0 mode tap user bbs   
      pre-up ip link set tap0 up   
      bridge_ports all tap0   
      bridge_stp off   
      bridge_maxwait 0   
      bridge_fd      0   
      post-down ip link set tap0 down   
      post-down ip tuntap del dev tap0 mode tap   
      
   FYI, this is all on the HOST... I have yet to get to setting up the vm   
   guest.   
      
   I did a lot of searches on the error message I got, and variations, and did   
   not find anything that gave me a hint as to what the issue might be.
