yes.. you're right.. Im working with ESXi over Sun X4250 at least one month and i like it. I always refuse work with Virtual Machines because i always needed all the memory and processor for my applications and i belived install a Virtual Machine Administrator wasnt a good choice. The times are changed.. Now, getting a powerfull server its more cheap and the "Core" of Vmware as changed as well translating their products to Free.

I hope VMWare still keep this needed for all the community and give a PLUS for the new Zimbra Vmware..
