A long and detailed description of the setup, but not what the problem is !
What am I missing here?
What isn't working ?
I have spotted one fundamental error, which is one I've made in the
past :-/ And I recall scratching my head for ages until I took a tea
break, and when I came back the penny dropped.
Dom0

192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

I'm guessing that Dom0 can communicate with devices in the
192.168.1.0/24 and 192.168.2.0/24 networks, but not those on the
wider internet or 192.168.3.0/24 ?
The routes for the latter are on the wrong interfaces :
The default gateway of 192.168.1.254 is reachable via eth0, not eth1.
The router 192.168.2.1 is reachable via eth1, not eth0.
DomU
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.3.0 192.168.2.1 255.255.255.0 UG 0 0 0 eth1
0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0 eth0
Ditto except eth0 and eth1 appear to be swapped round.
But this is inconsistent with other information provided :
vif = [
'mac=00:16:3E:24:79:D6, bridge=eth0',
'mac=00:16:3E:24:79:D7, bridge=eth1',
]
This suggests that DomU eth0 should be connected to the eth0 host
bridge, and similarly for eth1.
DomU
eth0 Link encap:Ethernet HWaddr 00:16:3e:24:79:d6
inet addr:192.168.1.201 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::216:3eff:fe24:79d6/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
eth1 Link encap:Ethernet HWaddr 00:16:3e:24:79:d7
inet addr:192.168.2.201 Bcast:192.168.2.255 Mask:255.255.255.0
inet6 addr: fe80::216:3eff:fe24:79d7/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
This backs that up.
So both of those are inconsistent with the DomU routing table shown.
