I know it''s hard to believe, with all of the amazingly contradictory
information out on the internet, but after 2 days of reading and testing
I''m still not 100% with getting my Xen environment networked properly.
I have my dom0 setup and it''s ALMOST happy. It can speak on the 2
needed networks.
10.175.8.0/21 is an internal network
10.150.8.0/24 is a natted network to the outside

I currently have one test Guest dom set up, mgixentest. It''s config
file looks as follows:
# cat /etc/xen/mgixentest
name = "mgixentest"
uuid = "8eb40858-96b7-baad-1390-d44c01342e43"
maxmem = 512
memory = 512
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ ]
disk = [ "file:/var/lib/xen/images/mgixentest-disk0,xvda,w" ]
vif = [ "mac=00:16:3e:7f:1e:33,bridge=virbr0" ]
My goal:
1. Each guest domN will be assigned an IP on either 1 or both of
the above networks (10.175.x.x or 10.150.x.x).
2. Each guest will be reaching from within the 10.175.8.0/21
network to and from other machines.
3. Each guest (if so supplied) will have external access to the
internet via the 10.150.8.0/24 network
Can someone please get me going down the correct path?
Thanks for any insight.
Jamie Duncan
