ports. Initially we will have <32 servers so they will all be
connected to the same comtrol panel, connected to alice.
-If alice, or alice's comtrol card, dies, we swap over
+If newcastle, or newcastle's comtrol card, dies, we swap over
- the port 0's of the two comtrol panels
- the two cables betwen the comtrol panels and the servers
-leaving alice and bob's ttyS0's still connected to the each other's
-comtrol port 0, but all the test boxes connected to bob.
+leaving newcastle and gateshead's ttyS0's still connected to the
+each other's comtrol port 0, but all the test boxes connected to
+gateshead.

* Infrastructure vlan (172.16.148.0/24)
Used for sshing between various service VMs.
- Data migration between alice and bob
+ Data migration between newcastle and gateshead
PDU
* Test vlan (172.16.144.0/22)
* infra dhcpd (isc), internal DNS, etc. [infra]
For completeness I also list
+ test boxes [test]
- + alice, bob main server physical hardware [test infra ext]
+ + newcastle,
+ gateshead main server physical hardware [test infra ext]
The two VMs marked [ext] need to provide service on a stable public IP
address. This could be achieved by giving them a public IP address
