[Xen-users] Network configuration problem
Greetings!
I have recently started using Xen on Debian Etch and am pretty much impressed
how well things worked out. Now I stumbled into an issue which I could not
resolve.
The situation:
1. I successfully installed dom0, and am running the Xen enabled kernel.
2. The dom0 system is connected to the web and it's IP address is pingable,
I can ssh into the dom0 system.
3. The dom0 system now has one hardware interface, named eth2, which is the one
connected to the web. This interface got an IP assigned from the providers
own network.
4. I do have a small 8 IP range network which from which I have configured two
IPs as eth2:1 and eth2:2.
5. eth2 and the virtual interfaces have different subnets, thus eth2 e.g. has
the address A.B.192.33, and eth2:1 is A.B.207.160, and eth2:2 is A.B.207.161.
Now I created guests and assigned eth2:1 and eth2:2 to them.
I can ping the guests IPs from the outside, and when I console into the guest
using xm console I can see it's ifconfig showing the correct IP.
But here comes trouble: neither do packages for the assigned IP reach the guest,
nor can I reach any IP from within the guest.
I couldn't find any solution to this issue, searched several hours on Wiki and
google. Could anyone give me some hints what I am doing wrong?
With kind regards,
Daniel S. Reichenbach
