Running Centos 5.4 with KVM on a Dell R610 server and I'd like to control which of the four ethernet interfaces are used for specific tasks
My ideal configuration would be
eth0 - Host traffic only, no virtual guests. Used for guest mirroring and management. eth1 - NAT guest traffic only, no address for local machine and in some environments in the same zone as eth0 eth2/3 - Allocated to two different bridge devices which might be in separate network zones.
The configuration of eth2/3 is fairly simple, my issue is restricting any NAT traffic to a specific ethernet devices, and ideally one with no local IP.
Any ideas?

So if I have this right, at the basic level you wish to have:
- One interface for Host machine
- Multiple interfaces for guest traffic
If your environment supports VLANs (802.1Q), might I suggest a trunk port on eth1 split up into different bridges to have the KVM guests go through to get on different VLANs/address spaces.
This is what I currently do for Xen and it works great. What kind of network setup to you have?
Not quite what I'm after.
My issue is I can't see any way to bring up NAT guests unless they are using a ethernet interface that has a address for the host OS.
eth0 - Host OS Traffic only eth1 - NAT traffic for any guests I don't want to bridge eth2 - Bridge traffic zone 1 eth3 - Bridge traffic zone 2
Setting up eth0/2/3 is ok, but eth1 is the issue.
