12:46:35 nkorabli Hey there! Would love to clarify Numa cpu pinning process in Openstack. I've went through all the docs I could find on that - but still one thing is not clear to me. Is that possible to assign an instance to a particular Numa cell? It seems like by default, when you launch a single CPU vm using numa, it won't be spread evenly across all numa cells, it will be pinned to the `cellid=0`.
12:47:15 nkorabli @here
12:50:11 sean-k-mooney nkorabli: that depends on your definition of assigin to a numa cell
12:50:51 sean-k-mooney nkorabli: you can request a vm to have a single virtual numa cell in which case openstack will create it and pin it to a single numa cell
12:51:30 sean-k-mooney nkorabli: you cannot however say that i want to boot this vm on numa cell 0 of host X. that would break the cloud abstration
12:57:01 openstackgerrit Claudiu Belu proposed openstack/nova master: POC: tests: autospecs all the mock.patch usages https://review.openstack.org/470775
12:59:05 nkorabli sean-k-moooney: I played a bit with that - I had single compute node with 2 numa cells(nodes). I launched a lot of VMs with a single CPU. Then checked how those VMs got distributed across those numa cells. Apparently, all of them got pinned to the first numa node and none to second.
12:59:45 sean-k-mooney are you using openstack kilo
13:00:02 sean-k-mooney or using a pci passthrough device.
13:00:03 nkorabli I used Liberty for that
13:00:10 sean-k-mooney thats your issue
13:00:26 nkorabli I also noticed this in the code: https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L4099-L4104
13:00:42 sean-k-mooney liberty had a bug where the numa virtual numa node was used to select the phyical numa node
13:00:57 sean-k-mooney that was expcitly never intended to be the behavior
13:03:11 nkorabli So, this behavior shouldn't be the same in older releases? I supposed that according to the link above - this issue hasn't been fixed yet..'
13:04:44 sean-k-mooney no you are miss understanding what i said. https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L4099-L4104 simply states that if we do not request a numa topology for a vm we leave the kernel spread the instaces.
13:05:51 sean-k-mooney by default vms created in openstack are not assumed to have memory or cpus that come from a single numa node
13:08:41 sean-k-mooney nkorabli: are several indirect ways that a numa topology can be requested on your behalf without you seting the hw:numa_nodes extra spec.
13:09:47 sean-k-mooney nkorabli: for example if you request hugepages a request for a singel numa node will implicitly be created. unless your request a numa topology via hw:numa_nodes
13:13:12 nkorabli If I specified `hw:numa_nodes=1` then it will use just one cell, right? (like `cellid=0`). I can't specify `hw:numa_nodes=2` for a single CPU instance either. So, I can't explicitly make use of both numa nodes when working with single CPU VMs?
13:15:56 sean-k-mooney nkorabli: if you specify hw:numa_nodes=1 for a single core vm flavor that vm can be placed on either of numa nodes on the host system but it will be affinitesed to which ever node it first starts on
13:16:49 sean-k-mooney nkorabli: if you dont spceify hw:numa_nodes at all it will implcitly float across all numa nodes and cores at the whim of the host kernel scheduler
13:18:28 sean-k-mooney nkorabli: to be more precise it will float across the cores specified via the vcpu_pin_set option in the nova.conf
13:19:01 sean-k-mooney nkorabli: if vcpu_pin_set is not specified it defaults to all cores
13:21:45 nkorabli alright, that's great! I was expecting behavior like this, just couldn't reproduce in Liberty. When I specified hw:numa_nodes=1, it started throwing errors like this: "No valid host was found. There are not enough hosts available." So, I thought it fills up the first node and never sees the second.
13:23:37 nkorabli This line also made me think this way: https://github.com/openstack/nova/blob/master/nova/virt/libvirt/config.py#L1976
13:24:15 nkorabli If I understand you right, this is an issue that appears in Liberty only?
13:25:32 sean-k-mooney https://github.com/openstack/nova/blob/master/nova/virt/libvirt/config.py#L1976 is referring to the virtual numa topology of the guest. not the host numa topology
13:26:32 sean-k-mooney the first release of openstack with numa support did a 1:1 mapping between the virtual cellid to the host cellid howerver that was a mistake that was correct in later releases
