No they are on different physical machines.

I would say software because on the same physical machines we had SLES +
XEN running for years without any kind of corruption.

I would tend to agree, but one cannot discount the effects of age. Could be that the OS switch happened just prior to some age induced failure in hardware.
 

Still, do you have a running Postgres instance or have you tried running a Postgres instance on CentOS that is not in a VM?
