The KVM guest is CentOS 5.3 running kernel 2.6.18-128.1.6.el5. The filesystem activity caused corruption on the filesystem being stressed (barely). I've also seen corruption on a CentOS 5.3 install running on a physical machine. One of my friends is now attempting to reproduce the corruption on Red Hat's release of the same package, and I'm trying to reproduce the corruption on 2.6.18-128. I suggest that anyone using that kernel check their filesystems and report any corruption that they find.
