New page

Using the virsh console [vm_name] command can be used to get a shell to the vm. This is very handy when there is no virt-manager/desktop environment or no ssh. Although you will need to get a shell up somehow.

This assumes that the configuration in the xml is correct with <serial> and <console> sections.

sudo systemctl status serial-getty@ttyS0

If this is not active.

sudo systemctl enable serial-getty-ttyS0
and
sudo systemctl start serial-getty-ttyS0

When creating the virtual machine make sure that you use the config --extra-args 'console=ttyS0,115200n8 --- console==ttyS0m115200n8'

Actually im going to add the whole shell script ive used for creating kvm guests.

#!/bin/bash
