On DomU (monitoring target):

1. Build and run libvmi's linux-offset-finder on the Xen DomU guest which
you would like to monitor. See the README and source code in the libvmi
source tree for how to do this.

2. Copy the running kernel's System.map file from /boot to the Xen
Dom0 guest.

3. Restart the Xen DomU guest.

On Dom0 (monitor):

4. Update /etc/libvmi.conf on the Xen Dom0 guest based on the previous
output from linux-offset-finder and the path to the System.map file.

5. Build guestrace and run "guestrace <guest name>" on the
Xen Dom0 guest.
