Hi

I've built new security groups to make sure they are in the correct project. I can start a new server manually using these security groups.

The error is coming from the nova compute node. Same error can't find security group.

I am creating the load balancer and specifying the project on the command line even.

openstack loadbalancer create --name lb25 --vip-subnet-id admin_subnet1 --project 5e168b652a374a02aff855a5e250b7f8

Kind of running out of ideas.

Hey Russell,

Are you able to share the outputs from:
$ openstack server show 524ae27b-1542-4c2d-9118-138d9e7f3770 -c id -c project_id -c security_groups -c status -f yaml

And:
$ openstack security group show0b683c75-d900-4e45-acb2-8bc321580666 -c id -c project_id -f yaml

I agree with James, my assumption would be that we will find they aren't in the same project, so Nova can't use that security group for the Amphorae. I'm not familiar with charmed openstack though, but it does look like James is from Canonical and might be able to advise on the specifics. 

All the best,

Hi

I am seeing the below error when creating a load balancer. The security group does exist, and it is the correct group (tagged with charm-octavia)

What am I missing here to resolve this?
