[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.

[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!

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.

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 [View Less]

Re: Security Group

Hello Benyamin: Please check the Neutron security group documentation. What you are doing is to filter by an inport, traffic type (IPv4, TCP) and a dst port. This is something that you can done using the SG API: https://docs.openstack.org/python-openstackclient/pike/cli/command-objects/… . Regards.

Instances shutting themselves down
by Karera Tony 24 Jan '24

24 Jan '24

Hello Team, I have an openstack environment with 4 compute Nodes however yesterday out of the blue, the Instances on one of the compute nodes started shutting themselves down. Then I realized the the compute service was disabled when I checked in Horizon. I enabled it and restarted the instances and all was well but I cant figure out what caused it. I have attached the nova_compute logs here incase someone would like to support https://paste.openstack.org/show/bxqpgjvqT3DlOYWoeejc/ Regards Tony Karera
