Re: [Xen-users] routed network (not only one vif needed?)
Hi
Thnx for the answer.
So do you think I need bridged network?
I have the dom0 (having public IP, and being also part of the private
network) and ths DOMU-s as the subnetwork (192.168.0.x).
I don't understand what will be happened with the network interfaces at
briding:
- There will be an xen-br0 interface created with my DOMU's IP address
- When starting my DOM1 a mew VIF interface on DOM0 will be created, but
there will be no interface created on DOM1.
What I would except: having one virtual interface on dom0, that all the
domU could see as gateway. On DOMu there should be an eth0 everywehere
where I would set the appropriate IP adresses, gateways.. So with that I'd
have a virtual router on DOM0. Maybe is this concept worng?
How schould I live with the interfaces created by xen bridge scripts in
this case?
Thnx
George

Hi!
Now I tried to set up xen for routed network. I didn't understand why so
much vifs will be create, as much as domains I have.
My routed network consists of the domain0 (with public IP), and
domainU-s as the subnetwork (192.168.0.x)
So I modified the vif-route script in order to have only one vif for all
domainsU-s (with ip 192.168.0.254). But in this case only the domainU
works, for that I created the vif. So I need more VIF in order to have
networking also in all my DomainU-s? all of these Vifs should have the
same IP address.
Why should that make sense? I do not see what you are after with this.
Routed networking implies that every domU is a subnet of its own, so it
has to have an address space (not only a single address) of its own.
Dom0 has to have a routing table that connects the dom0 NIC with the the
virtual subnets that the domUs are.
(My subdomains are in one private network (192.168.0.1))
Why don't you use bridging, then?
