Troubleshooting CSO Installation Issues


Salt Key Issue During CSO Installation


Description: The infrastructure services for the central infrastructure virtual machine (infravm) and the central microservices virtual machine (msvm) ran successfully. However, the Contrail Analytics virtual machine (contrail-analytics-vms) failed with the following key exchange error.

root@cso-central-2:~#salt-key -L


  1. Verify that the deployment script is running on the installer virtual machine and on the analytics virtual machine.
  2. Execute the following commands:
    root@cso-central-2:~#rm –rf /var/cache/salt*
    root@cso-central-2:~#sudo apt-get remove salt-minion
    root@cso-central-2:~#sudo apt-get purge salt-minion

TimeZone Error


Description: The following error message is displayed when installing the central microservices virtual machine.


This issue occurs only when the NTP server input is not synchronized with the virtual machine. Check the NTP server details in the setup assistant.

SSL Handshake Failure


Description: SSL handshake failures are reported on both regional services (regionalmsvm1 and regionalmsvm2) in Icinga.


  1. Edit the /etc/nagios/nrpe.cfg file at the regional microservices virtual machine. The allowed_hosts might have the central microservices virtual machine management address instead of the Operation, Administration, and Maintenance (OAM) address. Add the OAM IP address. For example:
  2. Send the kill –HUP command to the Nagios Remote Plugin Executor (NRPE) process.
    root@regional-msvm:/etc/nagios#ps aux | grep nrpe
    root@regional-msvm:/etc/nagios#kill -HUP 1428

Missing Interface on CSO VM


Description: When two virtual bridge interfaces(virbr0 and virbr1) on the server are mapped to eth0 and eth1, only one interface is listed in the CSO virtual machines. The second interface is not visible to the CSO virtual machines.

root@host:~# brctl show


  1. Assign an IP address to the second interface in /etc/network/interfaces.

  2. Set enable_data_interface to true for all virtual machines and set data_interface to virbr1 for cso-host in the provision_vm.conf file.
