Thanks for the answers. First of all I am new to the clustering
technology and trying to understand how it works. Thats why I can ask
funny questions, =)

What I ment is creating a supercomputer by  using a cluster of
computers(for example 7-8 physical servers) and on this supercomputer
installing vmware server or vmware esx and using vmware installing guest
OS es either windows or linux. Is this possible?

Thanks
