  1. Added below lines on virsh edit As per this: https://linuxadmin.io/enable-virsh-console-kvm/

CentOS Atomic images have the serial console redirected to kvm/qemu serial port.

To connect to the serial port and see the boot messages:

virsh list --all   # To list all VMs
virsh shutdown <centos-atomic-VM-name>  # Stop the VM
virsh start --console <centos-atomic-VM-name>   # Connect on the VM's console and start it

  • Thanks for your time - but i need to have this serial connection permanent , suppose in some situation if i cant reach the server using ssh then i can use virsh console to access its console – midhun k Mar 22 '20 at 02:17
  • You can use `virsh console ` to connect to console when VM is running – Mircea Vutcovici Mar 22 '20 at 05:16
