Title could be simpler, "An example configuration for live migration", i.e. drop
"of a"

 

This paragraph should be highlighted in a “Warning” or a “Note”:

“Make sure the directory is exported with the correct options, if you are
exporting the default directory /var/lib/xen/images/ make sure you ONLY export
/var/lib/xen/images/ and NOT /var/lib/xen/ as this directory is used by the xend
daemon and other Xen components, sharing it will likely cause unpredictable
behavior”

 

s/the exampled used/the example used/

 

"Run a simple loop inside the guest to print out time and hostname every 2
seconds." ... but the sample loop uses "sleep 3"

 

The text doesn’t match the commands – this whole first example of migration from
et-virt07 to et-virt08 is all messed up. For example:

“Initiate a live migration to et-virt08”

does NOT match the command

“[et-virt08 ~]# xm migrate --live xentesttravelvm01 et-virt07”

 

One of the samples starts with the line:

        # doit script

This will prevent the following line from being processed (by the kernel):

        #!/bin/bash

The doit line should be removed.
