+=item start the script B</etc/init.d/xencommons> at boot time
+
Most B<xl> operations rely upon B<xenstored> and B<xenconsoled>: make
sure you start the script B</etc/init.d/xencommons> at boot time to
initialize all the daemons needed by B<xl>.
+=item setup a B<xenbr0> bridge in dom0
+
In the most common network configuration, you need to setup a bridge in dom0
named B<xenbr0> in order to have a working network in the guest domains.
Please refer to the documentation of your Linux distribution to know how to
setup the bridge.
+=item B<autoballoon>
+
+If you specify the amount of memory dom0 has, passing B<dom0_mem> to
+Xen, it is highly reccomended to disable B<autoballoon>. Edit
+B</etc/xen/xl.conf> and set it to 0.
+
+=item run xl as B<root>
+
Most B<xl> commands require root privileges to run due to the
communications channels used to talk to the hypervisor. Running as
non root will return an error.
