RE: [Xen-users] HVM Migration

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

Thanks - Nick

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).


PS: Thanks for your response yesterday. :)

Subject: [Xen-users] HVM Migration

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
