I'm looking at it, yes.

Right, that can also be done in KVM and/or VirtualBox, the links gave examples.

I've the same set up but I'm not seeing traffic, good to know this should work.

For the routing problem, in basic-pluto-01 I see the initial

  west# ./../pluto/bin/wait-until-alive -I 192.0.1.254 192.0.2.254

fail.  Ah, west also has:

# netstat -nr
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.0.2.0       192.1.2.23      255.255.255.0   UG        0 0          0 eth1

so provided 192.1.2 carries traffic it should work.
