[Openstack] intentionally allow ip "spoofing"?

2012-07-19 Thread Xu (Simon) Chen
Hi folks, (Resending, since I did something wrong with the subject last time...) I wonder if there is a way to intentionally allow ip "spoofing" for certain VMs... The use case is the following. We have two DCs, both have openstack deployed. One tenant lives on both DCs, say 10.0.0.0/24 in DC1 a

Salvatore, This is a very interesting concept... I can see it being useful in our production environments... I wonder if we can make this a bit more general than "public or not"... Think about a generic ownership and "mode bits" concept of networks. For example, the infrastructure owner can crea

Narayan, If you do net.bridge.bridge-nf-call-iptables = 0 on the network controller, does floating IP still work? For each tenant/network, a subnet is created, and the nova-network has a .1 gateway configured on the bridge with the vlan interface plugged in. The packets from VMs are actually sen

[Openstack] multiple floating ip pools

2012-02-06 Thread Xu (Simon) Chen
Hi all, I am running devstack and got a dev instance of OpenStack running. I am happy to see the concept of multiple floating IP pools, and the per-floating-ip interface in the trunk, which I consider a very good basis for my blueprint proposal here: https://blueprints.launchpad.net/nova/+spec/mu

Re: [Openstack] multi_host networking, but not on all nodes?

2012-02-07 Thread Xu (Simon) Chen
My two cents... The current multi-host mode is really making the assumption that if the NC running in the dom0 is gone, all the VMs are likely screwed anyway. When you are talking about a middle-ground, you'll need to handle NC failures and load-balance among the NCs. You'll also need to worry ab
