Doc Type: Bug Fix
Doc Text:
Recently applied patch introduced a bug, which caused the Xen guest networking not to work properly on 64-bit Itanium processors. However, this bug also revealed an issue, which may have led to a data corruption. With this update, both errors have been fixed, and Xen virtual guest networking now works as expected.

Comment 4 Lei Wang 2010-10-26 09:33:20 UTC 
Verify this bug with kernel-xen-2.6.18-194.24.1.el5.ia64. 

Network connection worked as expected (ping,ssh,wget).

dmesg is without any 'Private data too big' message,details as below:

[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.18-194.24.1.el5xen #1 SMP Thu Oct 21 04:44:26 EDT 2010 ia64 ia64 ia64 GNU/Linux
[root@localhost ~]# dmesg |grep netfront
netfront: Initialising virtual ethernet driver.
netfront: device eth0 has flipping receive path.

So move bug status to VERIFIED.
