OK.. Looks like my test results were skewed by strict numa placement policy
set in the flavor, and my neutron ports being created against PCI devices
in a specific NUMA node.
For example, if I use a flavor I suspected of mapping to numa1, and if I
created V
Although it contradicts the idea of a cloud, I believe the CPU mapping between
the guest and the host is a valid case for NFV applications. The best that one
can do is to ensure vCPU and virtual memory are mapped to single NUMA node
within the host and to make sure the CPUs don’t float within th
We have use cases in our cloud which require vCPU-to-NUMA_node pinning
to maximise the CPU performance available in the guests. From what we’ve
seen, there was no further improvement when the vCPUs were mapped
one-to-one to pCPUs (we did not study this in detail, though, as with the
NUMA node pinni

Currently I see you can only direct which vCPUs are mapped to a specific
NUMA node
hw:numa_cpus.0=1,2,3,4
However, to get even more granular, is

Don't count on it! Setting up Neutron networking (if that's
what you're doing and not using Nova networking which is the
"old" way to do it) is a pain in the royal behind!!

I think I am missing something simple here.
I can see the DHCP requests coming into my network node, but
I dont see that the DHCP requests are being shuttled into the DHCP
namespace.
What is needed to direct DHCP requests into the DHCP namespace ?

I want to create a bond within my guest VM and trying to understand how to
create my neutron ports without allocating an IP for each VF created.
I just need one IP allocated instead of each VF(neutron port) being
allocated an IP.
I do not see anything within the neutron port api which supports som
