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;
