Hello all!
I have a big question to the Xen-gurus out there. I want to establish a tricky
virtual network with Xen cause I have to migrate my old network to a new one. A
suggestion is to buy a big machine which should work alone without any other
machines. Beneath is a draft of the desired network. It''s simmilar to
the existing network.
Domain2 and Domain5 each have privileged access to one networkcard which is
provided by domian0 (intra-/internet). So, there is no need for me to have a
network attached at domain0. And further I don''t want server processes
on domain0. Domain0 should only control the others. It should not be possible
for the Domain1 to 8 to "see" Domain0.
So, what''s the question? My problem is the virtual networking with Xen.
I''m still not good in configuring Xen so maybe someone can help me with
a little example. I don''t need a whole configuration-howto for the
drafted network but some hints in the way of virtual networking in Xen.
Thank you!
The virtual network should be like this:
+-------+
+--Domain4 Internet--+ |Domain0|
| | +-------+
| |
+--Domain3--+ +--Domain2--+
| |
| |
+--+ +--+
| |
Domain1
| |
+--+ +--+
| |
| |
+--Domain5--+ +--Domain6--+
| |
| |
+--Intranet +--Domain7
|
|
+--Domain8
Domain0: 192.168.0.1/24
Domain1: 192.168.1.1/24
Domain1 is the networkbackbone.
Domain2: 192.168.1.2/24
A.B.C.D/E (provided by ISP)
Domain2 is a firewall, a IDS and a router under NetBSD. The IP-address.
A.B.C.D/E use one of the physical networkcards.
Domain3: 192.168.1.3/24
192.168.3.1/24
Domain3 is a firewall, a IDS and a router under Linux.
Domain4: 192.168.3.2/24
Domain4 is a DMZ server (www, ftp and so on).
Domain5: 192.168.1.4/24
192.168.4.1/24
Domain5 is a firewall, IDS and a router under NetBSD. The IP-address
192.168.4.1/24 use one of the physical networkcards.
Domain6: 192.168.1.5/24
192.168.5.1/24
Domain6 is a firewall, a IDS and a router under Linux.
Domain7:192.168.5.2/24
Domain7 is an internal server.
Domain8:192.168.5.2/24
Domain8 is an internal server.
