Description tgb 2011-06-15 10:38:57 UTC 
Description of problem:
Kernel doesn't emit offline event for vif network interface on xen guest shutdown, so vif-bridge is not called.

Version-Release number of selected component (if applicable):
kernel-xen-2.6.18-238.9.1.el5
xen-3.0.3-120.el5_6.2

How reproducible:
Always

Steps to Reproduce:
1. run udevmonitor
2. Shutdown guest with "xm shutdown"
  
Actual results:
udevmonitor shows:
UEVENT[1308132822.664190] remove@/class/net/vif46.0
UDEV  [1308132822.664190] remove@/class/net/vif46.0
UEVENT[1308132823.150963] remove@/devices/xen-backend/vif-46-0
UDEV  [1308132823.150963] remove@/devices/xen-backend/vif-46-0
UEVENT[1308132823.151014] remove@/devices/xen-backend/tap-46-51712
UDEV  [1308132823.151014] remove@/devices/xen-backend/tap-46-51712

Expected results:
Offline event happens and vif-bridge executed.

Additional info:
"xm destroy" generates udev event as expected

This is an exact duplicate of bug 661985.

Guybrush, I think you won't find it in 5.6.z; it will be available in RHEL-5.7. LeChuck says hello.
