→Preparing the Xen Migration Environment
</pre>
Of particular importance in the above configuration is the ''no_root_squash'' which allows the target host to write to the ''/xen'' directory via NFS as ''super-user'', a key requirement for performing the live migration.Once the ''/etc/exports'' file has been modified the change needs to be exported using the ''exportfs'' command: <pre>exportfs -a</pre>
