Xen devel - May 2008 - 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
}

I would be interested in using this too for a project that I am working on.

Have you got any further on this work?

I don''t know the details yet, but I would be willing to look into it
more.

Do you have any new information or have you any other feedback on
the topic?

Cheers,
Todd
