+==== Firewall ====
+We run the firewall on the Host Node (HN).
+Stop all running VMs.

+</file>
+==== DAHDI ====
+Sangoma USB hardware timing source (internal UT50 and external UT51):
+http://sangoma.com/products/accessories/tools.html
+:!: Note that DAHDI will only work if the Host Node and the VE are the same $ARCH (32/32 or 64/64).
+:!: HPET or hardware timing source is important.
+Is HN kernel compiled with HPET and am I using it?
+<file>
+grep HPET /boot/config-2.6.32-11-pve
+cat /sys/devices/system/clocksource/clocksource0/available_clocksource
+cat /sys/devices/system/clocksource/clocksource0/current_clocksource
+</file>
+Change the current clock source, test then add to ''rc.local'':
+<file>
+echo hpet > /sys/devices/system/clocksource/clocksource0/current_clocksource
+</file>
+See also 'res_timing_timerfd'.
+<file>
+dmesg | grep dahdi
+dahdi_test
+</file>
+Acceptable score: >99.975
+=== Make DAHDI Timing Available to CTs ===
+This assumes Asterisk is running as the user 'asterisk'.
+<file>
+CTID=100
+vzctl stop $CTID
+vzctl set $CTID --devnodes dahdi/pseudo:rw --save
+vzctl start $CTID
+vzctl exec $CTID chown -R asterisk.asterisk /dev/dahdi /lib/udev/devices/dahdi
+</file>
+=== Alternate Method? ===
+You can export devices from the Hardware Node (HN) to the container (CT) by using the devnodes flag.
+You may need a line like this in the /etc/vz/conf/VEID.conf for the Asterisk VE:
+<file>
+DEVNODES="dahdi/pseudo:rw dahdi/ctl:rw dahdi/channel:rw dahdi/timer:rw "
+</file>
 ===== Templates =====
-OpenVZ containers are created from templates.  Since containers are not fully virtualized environments, there is no booting to CD/DVD drives or ISO images.
