LXC containers
by engineer2024 10 Jan '25

I am trying to setup OSA branch 29.2.0 caracal. Whenever I try creating lxc containers using setup-hosts playbook, the new containers of version ubuntu 22 , as is the host, are missing openssh-server packages. The file /etc/ansible/roles/openstack_hosts/vars/ubuntu-22.04.yml, doesn't mention the ssh package in the distro packages. How to get ssh pkgs installed in the lxc containers ? Please help with this issue

LXC networking
by engineer2024 10 Jan '25

I have observed that in the OSA setups, on the controller nodes, each lxc container has two networks inside , eth0, eth1 interfaces. Ideally eth1 should be attached to br-mgmt bridge via veth pair. When I do 'ip link show type veth' on the host node, it is listing both the veth interfaces for each lxc container, but it is not listing the other member of that veth pair. --- # ip link show type veth 9f9add59_eth0@if2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master lxcbr0 state UP mode DEFAULT group default qlen 1000 link/ether fe:b6:db:27:e4:a7 brd ff:ff:ff:ff:ff:ff link-netnsid 0 9f9add59_eth1@if3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br-mgmt state UP mode DEFAULT group default qlen 1000 link/ether fe:a8:30:7a:ac:3f brd ff:ff:ff:ff:ff:ff link-netnsid 0 --- --- # ip link show type veth | grep 9f9add59 72: 9f9add59_eth0@if2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master lxcbr0 state UP mode DEFAULT group default qlen 1000 73: 9f9add59_eth1@if3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br-mgmt state UP mode DEFAULT group default qlen 1000 # --- But I can't find the other member of the veth pair, for example, for the interface 9f9add59_eth1, in the ip list. But the containers are running and reachable on the br-mgmt network. How to find out the other end of a veth pair, which is connected to the bridge ?

[neutron] Proposal to deprecate and remove vlan_transparent config option
by Sławek Kapłoński 09 Jan '25

09 Jan '25

Hi, We have config option to enable vlan_transparent api extension currently. We will also have similar config option for vlan_qinq (it is now proposed in [1]). In both cases we have validation by mechanism drivers if option is or is not supported while networks are created. We can also filter out enabled API extensions by mechanism drivers, see [2] for example. So I proposed [3] to remove that config option and keep API extension to be loaded always if enabled ML2 drivers supports it. But before I will propose patch for that I would like to ask if there is maybe some use case for this config option really and maybe some of you somehow depends on it. In such case maybe we should keep it like it is now and don't remove it. Please let me know if you are using somehow this option.

[Tempest] Devstack to configure tempest on a remote node
by Jakub Libosvar 09 Jan '25

09 Jan '25

Hello stackers, I have been attempting to deploy a “spine & leaf” like topology for upstream testing job of the ovn-bgp-agent [1]. The idea is to have an all-in-one devstack VM where all openstack services are running. This VM is plugged to two leaf switches respectively with its two interfaces, and each switch is connected to the “spine” switch. With the leaf switches behaving as route reflected we can validate routes are advertised to the spine. Now in order to validate that, I need to execute the tempest tests on the spine. That means I want to use devstack on the spine VM that calls OpenStack services API on the devstack all-in-one VM. The spine VM should not have any openstack service running. The problem I’m struggling with that the tempest is configured based on the ENABLED_SERVICES for the current box. I tried to hack the spine VM portion by calling configure_tempest with custom ENABLED_SERVICES from a local.sh [2] which seems to configure the tempest.conf correctly but the stack.sh script calls test-config [3] phase after local.sh is invoked, which re-configures tempest.conf back to the state as if no OpenStack services were enabled. I kinda hit the wall and ran out of ideas for hacks/workarounds with the current devstack codebase. I thought one way of solving this would be to decouple ENABLED_SERVICES into two separate variables, one being used to configure services and one for tempest purposes but before I dive into that, I wanted to ask if anybody has any experience doing something similar (configuring only tempest with devstack) or maybe there is already some variable I am not aware of. Thank you for any inputs, ideas or suggestions :) Kuba [1] https://review.opendev.org/c/openstack/ovn-bgp-agent/+/936968 [2] https://review.opendev.org/c/openstack/ovn-bgp-agent/+/936968/54/playbooks/… [3] https://opendev.org/openstack/devstack/src/branch/master/stack.sh#L1482-L15…

RDO User Survey
by Amy Marrich 09 Jan '25

09 Jan '25

Hi everyone, During today's RDO meeting we had a few topics that we need further information on in order to make decisions. As a result, we have created a 2 question survey[0] to collect the needed information. This survey will remain open for 2 weeks so we can make plans for the Epoxy release with the gathered information. The first question is in regards to CentOS Stream version(s) for the Epoxy release, CentOS Stream 9 only, 10 only, or both versions. The second question is to determine whether future RDO releases will continue to be all releases or only SLURP releases, if SLURP are the only releases folks are using. Thanks, Amy 0 - https://forms.gle/44atURvazYPXVvwZ8

Nova create vm with special ipv4 and ipv6
by Alex Song (宋文平) 08 Jan '25

08 Jan '25

Hi Nova team, does nova support create vm with special ipv4 and ipv6? As port create with ipv4 and ipv6 works by: openstack port create 111 --network 10851e96-8995-4988-b819-0514b38d7353 --fixed-ip subnet=a564ac90-3ff3-47d7-8ae5-20e2666eaa3c,ip-address=172.24.4.54 --fixed-ip subnet=afa3c858-c3d3-4784-8964-2c46840b714d,ip-address=2001:db8::183 but vm create with ipv4 and ipv6 with the cmd openstack server create --flavor 1 --image 62254c92-a579-4c8a-a2f4-f2624cef8ec1 --nic net-id=10851e96-8995-4988-b819-0514b38d7353,v4-fixed-ip=172.24.4.53,v6-fixed-ip=2001:db8::188 test raise exception: openstack server create: error: argument --nic: Invalid argument net-id=10851e96-8995-4988-b819-0514b38d7353,v4-fixed-ip=172.24.4.53,v6-fixed-ip=2001:db8::188; either 'v4-fixed-ip' or 'v6-fixed-ip' should be specified but not both. So why nova doesnot support?

[ops][nova] How to make sure that on a hypervisor there is room for a VM with a specific flavor
by Massimo Sgaravatto 07 Jan '25

07 Jan '25

Dear all I have the following use case: I defined a flavor F for VMS with 10 VCPUs, 20 GB of RAM, 30 GB of root disk, 1 GPU XYZ. I use PCI passthrough to manage GPUs. I have only a XYZ GPU on my cluster (on a H hypervisor), so a VM using this flavor F must be "placed" to the compute node H (and this is not a problem: I know how to do that). H is very large: it has a lot of RAM and cores, so it can host other VMs that do not use GPUs. How can I make it so that VMs without GPU can go on H, but there must be room for a VM with flavor F (if it doesn't already exist)? Thanks, and happy new year ! Cheers, Massimo
