KVM Active Console Session exists for this domain | Fixed

Virtualization has changed the way we manage and use computing resources. However, like any technology, it comes with its set of challenges.

One common issue in the KVM environment is the “Active Console Session” error. Today, we are going to take a look at the reasons behind this error and explore solutions.

The “Active Console Session” error lets us know that there is already an ongoing console session for the specified virtual machine. This results in a conflict when trying to start another session.

• Existing Console Session:

  The error often occurs when there is already an active console session for the virtual machine. This will stop attempts to open a new console connection.
• Console Session Persistence:

  KVM prevents multiple simultaneous console connections to the same virtual machine by default. This ensures consistency and avoids conflicts.

Troubleshooting Tips

• Check Existing Sessions:

  Use tools like virsh to examine the status of existing console sessions for the virtual machine:

  virsh list

  This will give us information about the virtual machine’s status and any active console sessions.
• Close Existing Console Session:

  If an active console session exists, we can try closing it before opening a new one.
• Forcefully Close the Console Session:

  In cases where necessary, we can forcefully terminate the existing console session using the virsh command.

  virsh destroy our_domain

  We have to replace “our_domain” with the name of the virtual machine.

  After forcibly closing the existing session, we can start a new console session.
• Use Remote Desktop:

  Rather than using the console, we can try remote desktop solutions like VNC or SPICE to connect to the virtual machine. These solutions enable multiple remote connections without conflicts.
• Review KVM Logs:

  If the error still occurs, examine KVM logs for any error messages or warnings related to console sessions.
• Check for Conflicts:

  This command helps identify potential issues or conflicts related to console sessions, assisting in the troubleshooting process.

  journalctl -xe | grep kvm

Let us know in the comments which one of the above tips helped you resolve the error.
