I''m having an issue with migration (live or not) from one Xen system to another. Here''s my environment: - SLES10 SP2, Xen 3.2.0, Kernel 2.6.16 (.60-0.33) - HVMs running Windows XP SP3 - GPL PV Tools - Shared storage on OCFS2, using files for domU hard drive. The issue I have is that, after migration, the Windows domU pegs the CPU and is completely unresponsive. Doesn''t matter if the migration is a "live" migration or not, the results are the same. Anyone have any ideas as to what might be going on here? Thanks - Nick This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

Is it 32-bit XP? Since your symptom sounds the same as mine from yesterday with the same codebase (mine was Win2003, yours is XP; we're both using GPLPV; I too saw the processor pegged and the VM unresponsive) you might try the workaround James Harper suggested to me – disabling checksum offload and large send offload in the NIC – before doing the migration. For what it’s worth, my VM that had issues yesterday was also a “migrated” VM (not live).

Yep - XP 32-bit. Disabled those options on the net card, but still have the same symptoms...

Just got my second server updated and added to ocfs2 cluster.

No progress here. The PV domUs seem to migrate just fine, it''s the HVM ones that have issues. I haven''t tried an O/S other than Windows in an HVM for migration, either. I also need to try without the GPL PV drivers to see if maybe it is one of the known issues that James Harper mentioned in those drivers. -Nick>>> James Pifer <jep@obrien-pifer.com> 2008/12/17 17:33 >>>On Fri, 2008-12-12 at 12:31 -0700, Nick Couchman wrote:> I''m having an issue with migration (live or not) from one Xen system > to another.
