Hello guys,
I was wondering if anyone could give me some tips on how to setup an infinband network for the guests using KVM hypervisor. In particular,, I am looking at providing guest vms with the IPoIB interface which is available on the KVM hypervisor hosts. The current implementation of IPoIB support in Linux does not allow for bridging over the infiniband interface, so you can't really create a bridge interface, feed it to ACS and let vm guests use the high speed network. If I understand correctly, there should be a way to use network segmentation with GRE tunnelling, which should not need the creation of bridge interfaces. If this is so, I should be able to utilise IPoIB network interface with GRE separation as the guest network. Has anyone attempted to do something similar? Another question, does ACS advanced networking support the functionality of having two or more different network types within one zone/pod/cluster? For instance, could I have two guest network offerings, one with vlan separation over ethernet and another with GRE separation over IPoIB interface? Cheers Andrei
