35.8. Fully virtualized guest console access

Fully virtualized guest operating systems automatically has a text console configured for use, but the difference is the kernel guest is not configured. To enable the guest virtual serial console to work with the fully virtualized guest, you must modify the guest's grub.conf file, and include the 'console =ttyS0 console=tty0' parameter. This ensures that the kernel messages are sent to the virtual serial console (and the normal graphical console). To use the guest's serial console, you must edit the libvirt configuration file. On the host, access the serial console with the following command:
# virsh console
You can also use virt-manager to display the virtual text console. In the guest console window, select Serial Console from the View menu.
