Enable Virsh Console Access For KVM Guests

Log in via ssh or kvm virtual machine manager to the KVM guest system (virtual machine), not in the KVM host.

Run the following:

 $ sudo systemctl enable serial-getty@ttyS0.service Created symlink /etc/systemd/system/getty.target.wants/serial-getty@ttyS0.service → /lib/systemd/system/serial-getty@.service. 

 

 $ sudo systemctl start serial-getty@ttyS0.service 

verify it by looking into the VM’s configuration XML file from the Host:

 $ sudo virsh edit debian10-server3

Now start the virsh console of the guest system from the host using command:

 $ sudo virsh console debian10-server3 Connected to domain centos8 Escape character is ^] 

Press ENTER again and type your user name and password to connect to the guest machine. To exit, type Ctrl+]
