No, the host is Fedora 10.  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 

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.
