Mapping local SSD to virtual machine persistently
by Sang Tran Quoc 24 Jan '24

24 Jan '24

Hello community, I've got a question related to the raw device mapping to the OpenStack virtual machine. The situation is I have several SSDs along with my compute node and I would like to attach these SSDs to my virtual machine for enhancing the disk performance. My current solution is using command "virsh attach-disk <dom> <host-device> <guest-device>" but it not persistently and need to manual re-attach after hard-rebooting which lead to re-generate the xml vm structure. So, I wonder if there is an official solution for my problems. Thank you and welcome for every help in our community. Best regards, Sang Tran

I have network-northd/gateway_hosts defined as well as: neutron_neutron_conf_overrides: ovn: enable_distributed_floating_ip: True openstack_host_specific_kernel_modules: - name: "openvswitch" pattern: "CONFIG_OPENVSWITCH" This should by all accounts just work, but for some reason for me it's not, what steps have i missed?

Hello Benyamin: Can you specify what rules are you manually creating the OVN database? The code you are referring to is the sync tool. The goal of this tool is to sync both databases, OVN and Neutron. But please remember that Neutron is the CMS, is the only source of truth and it controls the network backend, in this case OVN. Any definition should be done in Neutron and any manual change in the OVN database will be restored or the environment will fail. Regards.

Hi, i have a question/issue related to multiattach feature in cinder i have an openstack cluster and i have configured multiattach in the openstack cinder now when i create 1 volume (with volume type multiattach) and attach it to 2 instances test1 and test2 *on test1 sudo mkfs -t ext4 /dev/sdb sudo mkdir /mnt/mydisk sudo mount /dev/sdb /mnt/mydisk touch /mnt/mydisk/shared_file echo "This is some shared content" | sudo tee /mnt/mydisk/shared_fileon test2 sudo mkdir /mnt/mydisksudo mount /dev/sdb /mnt/mydiskls /mnt/mydisk/cat /mnt/mydisk/shared_file* i can see the shared_file now when i add new files on test1 im not able to see it on test2 untill i unmount the volume with directory and mount the directory again to the volume on test2. what could be the solution for it? how can i make the volume share datas instantly between all the instances connected to the volume i have tried with ext4 and xfs file system Hope to hear from you soon Thank you!

[puppet][ec2-api] Retiring puppet-ec2api
by Takashi Kajinami 22 Jan '24

22 Jan '24

Hello, As announced earlier, the EC2API project has been marked inactive[1]. We'll carefully watch the discussion between TC and the project, but unless the inactive mark is removed and the project is re-added to 2024.1 releases, I'd propose retiring puppet-ec2api, based on inactivity in the EC2 API project as well as no actual user feedback to our module. In case you have any concern, please let me know. If I get no objections and the project status is not changed, I'll start the retirement process of this module at some point during this cycle (probably m-3 or in worst case no later than GA). Thank you Takashi Kajinami irc: tkajinam [1] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack…

Security Group
by benyamin sam khanyani 22 Jan '24

22 Jan '24

Hi, I am working on the security group and aim to extend its functionality by applying custom rules based on source and destination ports, arbitrary match criteria, actions, and so on. I did it by using ovn-nbctl commands and everything worked well. Unfortunately, the only issue is that I can not see my custom rules in MariaDB and I didn't find any other solution for defining security group rules with my desired options. So, I want to ask you how I can tackle this issue? Regards, Benjamin Sam
