Hi,
I'm running a two node 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 Dom0 (xen 3.0.3).
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
