xenbr0 / domU static IPs
Hi, I have a new xen hosting platform. I have given the bridge a static IP which I can ping/ssh to etc, when I create a new vm all works well apart from the networking. If I give DomU a static IP I can''t ping out from the box, Dom0 can''t ping the vm. I''m suspecting it just isn''t seeing the bridge but am unsure where to start looking. This is a very standard

No connection in DomUs with network-route
Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

Xen Networking Issue with CentOS 5.1
