[neutron][neutron-vpnaas] Propose to EOL stable/queens, stable/rocky and stable/stein branches or neutron-vpnaas
by Slawek Kaplonski 08 Sep '21

08 Sep '21

Hi, On our last meeting of the CI team we discussed the problem with broken stable branches (stein and older) in the neutron-vpnaas project [1]. I checked that last patches which were merged in those branches are more than year ago: * Queens - last merged patch in April 2019 * Rocky - last merged patch in February 2020 * Stein - last merged patch in September 2019 Giving the above and the current status of the CI in those branches, I propose to make them End Of Life. I will wait until end of next week for anyone who would like to maybe step up as maintainer of those branches and who would at least try to fix CI of them. If there will be no volunteers for that, I will EOL those branches in neutron- vpnaas.

Question about vDPA support for live migration
by Jeffrey Zhang 08 Sep '21

08 Sep '21

Hey everyone, I am testing vDPA on OpenStack Wallaby. I have set it up successfully. But I found there are several features that are not implemented, including live/code migration[0], which I wanted. Anyone know what's the latest progress about this? I found no talk about this.

[neutron] Slow router provisioning during full resync of L3 Agent
by Patryk Jakuszew 08 Sep '21

08 Sep '21

Hello, I have a long-standing issue with L3 Agent which I would like to finally solve - *very* slow router provisioning in L3 Agent. We are operating a Rocky-based OpenStack deployment with three bare-metal L3 Agent nodes running in legacy mode. After restarting the L3 node, it takes a really long time for the L3 agent to become fully operational. There are two parts of resync which take much time: getting a list of routers from neutron-server and actually recreate them in the L3 node. While the long running time of router list retrieval is somewhat understandable, the router provisioning process itself proves to be very troublesome in our operations tasks. In our production deployment with around 250 routers, it takes around 2 hours (!) to recreate the router namespaces and have the L3 node fully functional again. Two hours of router re-provisioning is actually an optimistic scenario, this proved to be much longer during the outages we encountered (sometimes the sync took nearly 6-8 hours). This effectively prolongs any maintenance upgrades, configuration changes and OpenStack release upgrades. Another thing is, on that same production environment the first 100 routers usually get provisioned fast (around 30 minutes), after that it slows down with each router - this kind of non deterministic behavior makes it hard to communicate the maintenance finish ETA for our users. We also have a test environment with Stein already installed, where this problem is also present - full resync of 150 routers, with only one external gateway ports, takes around an hour to complete. Are there any operators here who also encountered that issue? Does anyone have any experience with similar situation and are willing to share their observations and optimizations? -- Regards, Patryk Jakuszew

[devstack][openstack-qa] DevStack on VirtualBox with Host-only Adapter
by os-user157 08 Sep '21

08 Sep '21

Hi all, I'm trying to deploy DevStack inside an Ubuntu Server 20.04.3 LTS virtual machine inside VirtualBox, but I'm struggling a lot, I got a lot of different errors. My use case: I want to test Zuul and DevStack, so I'll create a virtual machine for DevStack and one for Zuul, both on VirtualBox. I'm using a Host-only adapter with CIDR 192.168.200.0/24, and I need DevStack to be accessible on this network, and to use this network as the floating range for giving floating IP addresses to instances inside DevStack, so that Zuul can also access them. My local.conf: https://paste.openstack.org/show/809182/ Screenshots of the network configuration of my VirtualBox VM: First adapter, NAT (used for internet connectivity): https://i.imgur.com/C7XTiLJ.png Second adapter, host-only, used for communication with my Windows host and other VMs in the same network: https://i.imgur.com/Qeciuqx.png DevStack is erroring with the arping command on lib/neutron-legacy, arping gets 0 responses and exits the script with exit code 1 Does anyone have experience in dpeloying DevStack inside VirtualBox in such manner? I really need some help with this, if anyone could give me some ideas of waht could be wrong, it'd very much appreciated! Thanks.

Tenant vlan Network Issue
by Karera Tony 08 Sep '21

08 Sep '21

Hello Team, Whenever I create an internal network with type vlan. The Instances don't get IPs but for external Network it's fine. Below is the etc/kolla/config/neutron/ml2_conf.ini file [ml2] type_drivers = flat,vlan,vxlan tenant_network_types = vlan,flat mechanism_drivers = openvswitch,l2population [ml2_type_vlan] network_vlan_ranges = physnet1 [ml2_type_flat] flat_networks = physnet1 Is there something I need to change or I need to configure the interface differently Regards Tony Karera
