[Xen-devel] vif-common.sh call on xm shutdown / xm destroy

Dear list,

I'm currently modifying the vif-common.sh script in order to be able
to implement custom iptables rules for different guests.

As I can see, when a guest is created with xm create, vif-common.sh is
called with the "online" command. Perfect.

When the guest shutdown itself, vif-common.sh is not called, neither
when I shut down the guest with "xm shutdown" command.

But if I kill the guest with "xm destroy", the vif-common.sh is called
with command "offline".

Is it right that xm shutdown doesn't call vif-common.sh ?

I was expecting it to be executed when a shutdown is issued, in order
to clean the iptables rules for this particular guest.

Any ideas ?

btw: here is my custom vif-common.sh code:

frob_iptable()
{
 if [ "$command" == "online" ]
 then
   # Adding custom chain
   iptables -N "$vif"
   if [ -e /etc/xen/fw/$vif.rules ]
   then
     source /etc/xen/fw/$vif.rules
   else
     if [ -e /etc/xen/fw/default.rules ]
     then
       source /etc/xen/fw/default.rules
     else
iptables -A "$vif" -j ACCEPT fi
   fi
    # Forwarding the packets to the right chain
   iptables -A FORWARD -m physdev --physdev-in "$vif" "$@" -j "$vif"
  else
   echo "debug" >>/tmp/debug.log
   # Removing the chain forward
   iptables -D FORWARD -m physdev --physdev-in "$vif" "$@" -j "$vif"
   # Flushing the custom chain
   iptables -F "$vif"
   # Removing the custom chain
   iptables -X "$vif"
 fi
}
