Hi Brady,

See some feedback from testing your latest branch, from an hour ago.

Huge diff is expected, because there is no reference console output in that 
test directory. I didn't not add east.console.txt and west.console.txt so 
diff will be huge.

I just read the whole output until we are confident to commit reference 
output:) I noticed one error when adding connection in the test.

ipsec add west
003 ERROR: "west": ip_addr_xfrmi_store_ips() ifinfo_response NULL
002 "west": added IKEv2 connection

add leftinterface-ip=192.0.1.251/24 in west.conf.

interface-ip=192.0.1.251/24 will be rightinterface-ip=192.0.1.251/24 and no 
effect on west.  In basic-pluto-01 west is left.

Assuming configuration is correct I expect 3 hunks differences to 
basic-pluto-01.

1. ipsec look and  xfrm policy should have something like the following line

+ if_id 0x1

2. xfrm state also should have the the same if_id

+ if_id 0x1

3. route should be point to ipsecX and not to via 192.1.2.23

- 192.0.2.0/24 via 192.1.2.23 dev eth1
+ 192.0.1.0/24 dev ipsec1 proto kernel scope link src 192.0.1.251
+ 192.0.2.0/24 dev ipsec1 scope link

"192.0.2.0/24 via 192.1.2.23 dev eth1" probably should be manually deleted
check westinit.sh first line where I delete that route.

the above diff appear due difference between KVM and namespace and not 
actually working xfrmi and leftinterface-ip. Refrence is output from kvm.
