[Fedora-xen] Live migration fails depending on on the kernel Version of DomU

Hi,
I''m running a two node cluster xen-Cluster with CentOS 5.3.
I''m using
gfs2 for the  cluster filesystem and kernel 2.6.18-128.1.6.el5xen #1 SMP
for the Dom0 kernel.

Live migration works fine as long as the DomU guest is running CentOS 5.3
or SLC 4.7 with kernel version 2.6.9-55.EL.cern. But if the SLC 4.7 guest is
running the current 2.6.9-78.0.17.EL.cern kernel, the migration freezes 
without
an error message.

Any idea why the DomU kernel has an impact on live migration? Is  there a
possibility to migrate a DomU guest running kernel 2.6.9-78.0.17.EL.cern?
Thanks in advance,
Harald

This is fedora-xen list, not centos-virt .. :) 

This _sounds_ like upstream bug/issue, so you might want to get RHEL support
contract and then report it to Redhat..

Or you could try rhelv5-list or xen-devel.
I can''t really help you with the actual issue..

Re: [Fedora-xen] Live migration fails depending on on the kernel Version of DomU

what is the architecture of Dom-0 and userdomain? both the same (e.g. 32bit)?
