KEY POINTS:
  * If we use the same instance of vmx multiple times, irb macs with be the same and communication won't happen unless we do things like this:

  set interfaces irb unit 400 mac 00:05:86:ce:b0:03

----

TODO:\\
  * Review project documentation
  * libvirtd assigns the fxp address via dhcp but also gives a default route (ie 0/0 via fxp). we need to fix this
    * option1: play with dhcp kvm settings so it doesn't give a def route
    * option2: automate this: 1. grab ip in fxp0 2. remove dhcp config from fxp0 3. add static route (see below).
    * option3: do it manually:

  [edit interfaces fxp0 unit 0 family inet]
  -       dhcp;
  [edit interfaces fxp0 unit 0 family inet]
  +       address 192.168.121.87/24;
  [edit routing-options static]
       route 10.8.40.0/23 { ... }
  +    route 192.0.0.0/8 next-hop 192.168.121.1;
