Hi Muriel,

For XenServer specific issues you should generally either contact
XenServer support or make use of the appropriate XenServer forums rather
than this list which is for the development of the upstream xen.org
version of Xen.

If you see different behaviour based upon which hosts you are migrating
between then that, to me, suggests a XenServer issue in the first
instance.

However if you have reason to believe that the issue is specific to the
guest kernel rather than the use of XenServer as a host then please
provide full details of the guest, i.e. the distribution in use, where
the kernel came from, the .config used to build it, the guest
configuration and full guest console logs etc.

There was a second patch at the end of that thread, which did you use?
Have you tried the xen/stable-2.6.32.x branch from xen.git?
Thanks,
Ian.
