Unable to Establish Connection to KVM Host

Unable to Establish Connection to KVM Host

KB ID: 221012
Issue:
Encountering the specified error in BDRShield indicates a failure to establish a connection with the designated host, identified by either its Hostname or IP Address. The error message advises users to verify the installation and running status of the BDRShield Delegation Service (BDS) on the host.
Resolution:
To rectify this error and successfully establish a connection to the host, follow the steps outlined below:
1. Check the service status:
   If BDS is in a stopped state, initiate the service using the following steps:
  1. Navigate to the location: /home/vembuintegrationservice/Vembu/VembuIntegrationService.
  2. Execute the command: `sh startVembuIntegrationService.sh`
2. Verify Port status:
   For port 42005:
  1. Open the Terminal and run the command: `netstat -anp | grep 42005`
  2. Ensure that port 42005 is in use.
   For port 5000:
  1. Open the Terminal and run the command: `netstat -anp | grep 5000`
  2. Ensure that port 5000 is in use.
Note: If the issue persists after restarting BDS, check for potential network connectivity or firewall issues on the host. Use the command `sudo firewall-cmd --add-port=5000/tcp` to add port 5000. Additionally, confirm that BDS is functioning correctly and there are no environmental factors affecting the connection.
