You have not specified what distribution, version of libvirt are you using.

First, can you ensure if you have serial console set up in your guest by checking if you
have the below directives in your guest kernel's command line options (in /etc/grub.conf)

----
console=tty0 console=ttyS0,115200
----

If not, you can add it by running the below (ensure the guest is shut-off):

# virt-edit guest /etc/grub.conf

'virt-edit' tool comes with libguestfs-tools-c package.
