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 â disabling checksum offload and large send offload in 
the NIC â before doing the migration.

For what itâs worth, my VM that had issues yesterday was also a âmigratedâ 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
