Troubleshooting

If you use OpenStack Terraform Provider for migration, an issue with the default security group name may occur.

In a project with two SDNs (Neutron and Sprut), networks have a default security group named default.

OpenStack Terraform Provider works only with security group names, not IDs. This causes a conflict because the provider cannot uniquely determine which default security group to use.

• Use the VK Cloud terraform-provider as it allows using IDs for security groups.

• Change the security group name in the Terraform code:

  1. When creating a VM, specify the default security group in the manifest. The VM will be created successfully, but when executing the terraform plan command, the default-sprut security group will be returned, and the state file will not be able to update.
  2. Manually change the security group to default-sprut in the manifest.

• Fully migrate the project to the Sprut SDN, then disable the Neutron SDN in the project by contacting technical support.

• If virtual machines are rarely created, change the state file manually. Specify security group = "default-sprut" in the state file and save it.

• Do not use default security groups.
