It would be interesting to see whether or not this is SMP-related. It's also interesting that someone said they couldn't reproduce corruption when using 2.6.7 for the non-privileged guest OSes.I'm seeing this corruption on a single CPU machine, with a single 2.4 guest running but idle. I only ran one 2.6.7 guest, and I didn't give it any work, but it didn't take any load in the 2.4 guest to provoke problems.Do you mean a single 2.4 or 2.6 guest in addition to your 2.4 DOM0? Yes, that's right. With just the 2.4 domain0 on its own, everything seems fine.
