[glalnce][ceph] delete snapshot after creating instance
by Satish Patel 25 Jan '24

25 Jan '24

Folks, I have two openstack clouds and both have their own Ceph backend storage.I am trying to migrate instances from openstack A to openstack B. 1. Take a snapshot from A 2. Export snapshot and import to B 3. Create instance on B 4. Delete snapshot - (I am getting error because its in-use) Because it has a parent reference to that volume. How do I remove the reference so it will let me delete a snapshot. Reason I am asking is because I have so many VMs to migrate and don't want glance to have 100s of entities in those snapshots. What is the alternative here? I can try qcow2 if that is the final solution to make it clean. # rbd -p volumes info volume-f2b2aec2-cc57-49e5-aca1-54b5a7ee9f3a rbd image 'volume-f2b2aec2-cc57-49e5-aca1-54b5a7ee9f3a': size 40 GiB in 5120 objects order 23 (8 MiB objects) snapshot_count: 0 id: 5473c827864fed block_name_prefix: rbd_data.5473c827864fed format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten op_features: flags: create_timestamp: Fri Jan 19 19:03:25 2024 access_timestamp: Wed Jan 24 15:51:04 2024 modify_timestamp: Wed Jan 24 15:52:40 2024 parent: images/3708f961-fb74-49f1-ab9b-40cf7954abed@snap overlap: 40 GiB

[kolla][trove] Best practice to make guest-agent communicate with RPC
by Satish Patel 25 Jan '24

25 Jan '24

Folks, I am trying to find a kolla-ansible doc related to how to implement trove in production with best practices. Especially when a guest-agent (running inside VM) talks to RPC service. How are other folks doing in their environments? In most cases RPC is an internal service and not visible to any guest VMs. Looking for some guidance.

[Kolla-ansible][Ironic] Ironic PXE boot not working
by Jayesh Chaudhari 25 Jan '24

25 Jan '24

Hi, I have deployed following setup Openstack Version : Yoga Deployment Method : Kolla-ansible Node Provisioning tool : MAAS Now I am trying to integrate ironic service in it for BareMetal as a Service. My configuration for ironic in global.yml is following: enable_ironic: "yes" ironic_dnsmasq_interface: "ens2f0" #10G interface ironic_dnsmasq_dhcp_range: "10.145.50.50,10.145.50.60,255.255.255.192" ironic_cleaning_network: "ironic_provisioning_network" ironic_dnsmasq_default_gateway: 10.145.50.1 ironic_dnsmasq_boot_file: "pxelinux.0" ironic_inspector_kernel_cmdline_extras: ['ipa-lldp-timeout=90.0', 'ipa-collect-lldp=1'] ironic_http_port: "8089" ironic_enable_keystone_integration: "yes" My deployment is successful, but when I try to create openstack instance with baremetal flavor it stuck in pxe boot. If I use my 1G interface as ironic_dnsmasq_interface it pxe boot from MAAS. Is there any way I can use MAAS with ironic ? or how I can proceed with 10G interface? Thanks, Jayesh

[ops] help with openstack horizon
by Shubham Yadav 24 Jan '24

24 Jan '24

I have a question, is it possible to set in Horizon just one language - English? I mean that if you are new and login to openstack it will automatically set the language according to your browser. This could be sometimes confusing when you want to navigate by phone somebody with low expertise in OpenStack. is there any conf i can add in my horizon or theres any other way that stops browser from changing language in horizon? Hope to hear from you soon Thank You!

How about ephemeral storage with the ssd? 龚永生浙江九州未来信息科技有限公司 99CLOUD Co.

I also have questions regarding to your suggestion as below: @smooney@redhat.com Did you mention about cinder-volume with LVM driver? I tested it before, but the performance does not meet the requirement cause of the transportation of data via iSCSI protocol and it hard to compare with direct attach via libvirt. Your second idea are using flavor with ephemeral disk, right? @Karl Kloppenborg Your workaround suggestion looks good to me; I will search around for the accurate RabbitMQ event as you mentioned. Best Regards Sang.

One option (which will require a bit of programming on your part) is to listen to the events that might impact the libvirt generation and execute the commands on your behalf. This would necessitate knowing/storing that VM->Device mapping somewhere, i.e a database. Thanks, Karl.

Thank you and welcome for every help in our community. This is currenly not supported in openstack. we have discussed adding local storage functionality to nova in the past but its non triavial since we woudl need a new rest api to allow attaching/detaching them and schduelr intengration. unfortuntly that means that today you cannot achive your goal. if you need to attach addtional storage dynamically your only option is cinder volumes. you can provide addtional storage in the flavor but only statical > > Best regards, > Sang Tran
