[Xen-users] New to list & network-questions

[Hardy <hardy@xxxxxxxxxxxxxxxx>]

Hi to everybody,

I'm new to this mailing-list, so correct me, if I'll make any mistakes :D


The problem I have since 3 months now is the networking with XEN 3.0.1:
I run a debian (originally a kernel 2.6.8), but I looked and searched much 
in the www, so i got the right one compiled. (Not as hard as you may think 
now :D )
Now I'm running a dom0 and a domU. In domU I want to run servers (e.g. 
webserver, mailserver, aso.) so I have to forward the expected ports. With 
XEN 2.0.7 no problem :D So I installed/compiled XEN 3 and I looked at the 
ifconfig-table. I was scared, terrible scared :D
So my actually configuration is the following:
(The server is a rent rootserver.)
-> DHCP-address to the main-eth-adapter (given by provider)
-> static-intranet-IP-address for the xenbr0 (x.y.z.1) (ifconfig from dom0)
-> static-intranet-IP-address for eth0 (x.y.z.100) (ifconfig from domU)
-> iptables-forwarding with terrible complex rules.
Its working, but I think its very suboptimal. Further the memory of dom0 is 
falling an falling. And the server is rebooting automatically and 
periodically because of to less memory.
-> Whats going on? I'm no XEN-expert, but I think its the terrible 
network-construction.
-> How to setup this network correct?


Please, give me some links and hints. (For my memory-problem and a correct 
network-setup)
Thanks and greeting from Germany,
Hardy
