How to create a dummy network interface (and/or bridge)
Good day all together,
I have set up a linux-server with XEN running three nodes of an Oracle Cluster plus one OpenFiler iscsi host. Those DOMs create a lot of traffic under stress:
1. Network traffic from/to a seperate bare-metal server in the LAN.
2. traffic between all three nodes and the OpenFiler
3. traffic via "interconnect" between the three cluster-nodes
I tried to create the three interfaces needed via one network-bridge on the xen-network-interface, which ended up in a very weak cluster which, when stressed, performs much worse than even a single-database instance on much weaker hardware while the connection to the Dom0 almost breaks down.
My idea is to create a dummy network interface (or two) to bring the network traffic away from the xen-interface and splitting it up.
How can I create a new bridge on the Xen-Host without binding it to a physical interface? Can somebody guide me?
