RDO User Survey
by Amy Marrich 08 Jan '25

08 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) 07 Jan '25

07 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

I have set up OpenStack using Kolla Ansible with OVS and OVN. On one compute node, meters are functioning correctly, but on another, I am encountering an issue. Both nodes use the system datapath, have the same kernel version, and run the same version of OVS. Despite this, the problem persists. Has anyone experienced a similar issue? What could be the root cause? For example, I have two compute nodes. One of them does not have any issues, but the other meter did not work . following compute meter does not working: > sudo docker exec -it openvswitch_vswitchd bash (openvswitch-vswitchd)[root@compute1 /]# lsmod | grep open openvswitch 172032 13 nsh 16384 1 openvswitch nf_conncount 24576 1 openvswitch nf_nat 49152 1 openvswitch nf_conntrack 172032 6 nf_nat,nfnetlink_cttimeout,openvswitch,nf_conntrack_netlink,nf_conncount,ip_vs nf_defrag_ipv6 24576 3 nf_conntrack,openvswitch,ip_vs libcrc32c 16384 6 nf_conntrack,nf_nat,openvswitch,btrfs,raid456,ip_vs (openvswitch-vswitchd)[root@compute1 /]# ovs-appctl dpif/show-dp-features br-int Masked set action: Yes Tunnel push pop: No Ufid: Yes Truncate action: Yes Clone action: Yes Sample nesting: 10 Conntrack eventmask: Yes Conntrack clear: Yes Max dp_hash algorithm: 0 Check pkt length action: Yes Conntrack timeout policy: Yes Explicit Drop action: No Optimized Balance TCP mode: No Conntrack all-zero IP SNAT: Yes MPLS Label add: Yes Max VLAN headers: 2 Max MPLS depth: 3 Recirc: Yes CT state: Yes CT zone: Yes CT mark: Yes CT label: Yes CT state NAT: Yes CT orig tuple: Yes CT orig tuple for IPv6: Yes IPv6 ND Extension: No (openvswitch-vswitchd)[root@compute1 /]# ovs-ofctl -OOpenFlow15 meter-features br-int OFPST_METER_FEATURES reply (OF1.5) (xid=0x2): max_meter:0 max_bands:0 max_color:0 band_types: 0 capabilities: 0 (openvswitch-vswitchd)[root@compute1 /]# ovs-vsctl --version ovs-vsctl (Open vSwitch) 3.3.2 DB Schema 8.5.0 (openvswitch-vswitchd)[root@compute1 /]# uname -r 5.15.0-86-generic (openvswitch-vswitchd)[root@compute1 /]# uptime 08:27:39 up 87 days, 19:51, 0 users, load average: 3.36, 4.58, 4.19 ====================== following compute working without issue: > sudo docker exec -it openvswitch_vswitchd bash (openvswitch-vswitchd)[root@compute2 /]# lsmod | grep open openvswitch 172032 23 nsh 16384 1 openvswitch nf_conncount 24576 1 openvswitch nf_nat 49152 1 openvswitch nf_conntrack 172032 6 nf_nat,nfnetlink_cttimeout,openvswitch,nf_conntrack_netlink,nf_conncount,ip_vs nf_defrag_ipv6 24576 3 nf_conntrack,openvswitch,ip_vs libcrc32c 16384 6 nf_conntrack,nf_nat,openvswitch,btrfs,raid456,ip_vs (openvswitch-vswitchd)[root@compute2 /]# ovs-appctl dpif/show-dp-features br-int Masked set action: Yes Tunnel push pop: No Ufid: Yes Truncate action: Yes Clone action: Yes Sample nesting: 10 Conntrack eventmask: Yes Conntrack clear: Yes Max dp_hash algorithm: 0 Check pkt length action: Yes Conntrack timeout policy: Yes Explicit Drop action: No Optimized Balance TCP mode: No Conntrack all-zero IP SNAT: Yes MPLS Label add: Yes Max VLAN headers: 2 Max MPLS depth: 3 Recirc: Yes CT state: Yes CT zone: Yes CT mark: Yes CT label: Yes CT state NAT: Yes CT orig tuple: Yes CT orig tuple for IPv6: Yes IPv6 ND Extension: No (openvswitch-vswitchd)[root@compute27 /]# ovs-ofctl -OOpenFlow15 meter-features br-int OFPST_METER_FEATURES reply (OF1.5) (xid=0x2): max_meter:200000 max_bands:1 max_color:0 band_types: drop capabilities: kbps pktps burst stats (openvswitch-vswitchd)[root@compute2 /]# ovs-vsctl --version ovs-vsctl (Open vSwitch) 3.3.2 DB Schema 8.5.0 (openvswitch-vswitchd)[root@compute2 /]# uname -r 5.15.0-86-generic (openvswitch-vswitchd)[root@compute2 /]# uptime 08:29:47 up 87 days, 19:53, 0 users, load average: 11.23, 13.13, 13.29

custom playbook for nova
by engineer2024 06 Jan '25

06 Jan '25

can anyone guide me what are the tasks required for configuring nova service in OSA, so that I want to execute only those tasks and db steps , skipping the package installation steps. So I need to run nova playbook just to configure the nova like nova.conf, populating it with relevant options, do nova db migrate and then just restart the services. Is there a way to do it ? Thanks elinux

yoga to antelope upgrade path
by Satish Patel 05 Jan '25

05 Jan '25

Folks, I am running yoga in production with ovn driver and planning to upgrade to the 2023.1 release. Are there any issues to directly go to 2023.1 before intermediate release? Or anything critical I should be aware of?
