Hello Xen
Users.
A little bit on how
I got networking to route using Xen:
- Compile dom0 and
domU kernels with Advanced routing support
- My doms all have
dual nics on separate networks.
- dom0 connects to two different networks and
acts as a router for domU's
- domU creates a separate subnet on each
interface and traffic is routed through dom0
- I used policy
based routing to create additional routing tables for each interface and source
routing to direct traffic
- add tables in
/etc/iproute2/rt_tables
- In all doms I
create a default route for each interface using the local nic's address as the
gateway
- ip rule add from 192.168.168.0/24 table
r1
- ip route add default via 192.168.168.2 table
r1 (address for local nic)
- In dom0 I create
additional tables specifying the next hop for domU traffic
- ip rule add from 192.168.167.0/24 table
r2
- ip route add default via 192.168.168.1 table r2 (address for next
router in the chain)
- In my xen config
file, I specify the vif name, and changed the sxp file to use network-route and
vif-route
- I modified
vif-route to assign an IP address to the vif interface based on vifname
parameter
I hope this
information is helpful. And I would like to thank xen users who's input I
used to make this work.
