      Kubernetes Version: v1.27.4+deb2c60

      How reproducible:
      100%

      Steps to Reproduce:
      1. Deployed vm to openshift virtualization cluster from RHACM hub - vm is successfully deployed
      2. Start the vm with 'virtctl start vm' - vm is running
      3. Access the vm console - 'virtctl console vm', login and write data files
      4. After about 10 minutes the VM shuts down with the message below:
      5. Restart and access the vm, same happens. Reproduced this multiple times

      The system is going down NOW!
      Sent SIGTERM to all processes
      Sent SIGKILL to all processes
      Requesting system poweroff
      [ 687.879014] sd 1:0:0:0: [sda] Synchronizing SCSI cache
      [ 687.880156] sd 1:0:0:0: [sda] Stopping disk
      [ 687.973945] reboot: Power down

      You were disconnected from the console. This has one of the following reasons:

      • another user connected to the console of the target vm
      • network issues
        websocket: close 1006 (abnormal closure): unexpected EOF

      Actual results:
      VM shuts down unexpectedly with SIGTERM sent to all processes

      Expected results:
      VM should remain up and running
