           Summary: vif-script offline not called on paravirtual guest
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: cthunes@xxxxxxxxxxxxx

When xm shutdown is called for a guest a udev offline event is not triggered by
the kernel which in turn causes the vif network script to not be called to
remove iptables rules and decommision the interface. From

SUBSYSTEM=="xen-backend", KERNEL=="vif*", ACTION=="offline", RUN+="$env{script}

The currect vif-script should be called in reponse to an 'offline' event which
is not being triggered. We have found this problem in 3.2.1 and -unstable with
kernel revision 9829b72f4a99. Host system is Debian 4.0 stable amd64. If a
guest is destroyed instead of shutdown we do not see this issues nor do we see
this issue with HVM guests. online events are triggered without issue.
