No - not even close. The reality is that Oracle will not ask you to change the hypervisor. Not in theory or in practice. Among other things, that's illegal. There are already lawsuits underway in related actions by Oracle, which I won't get into here. That would take too long and Groklaw does a batter job anyway. Ask Oracle what certification means. And ask them if it's certified on specific hardware. You'll find that certification means pretty much nothing from a practical perspective. Certification in this regard is basically a marketing and FUD campaign on the part of Oracle to scare you to buy their hypervisor product, which is clearly inferior. Check out the latest Gartner Magic Quadrant report on OVM if you need to see 3rd party assessments of that (despite that I do not work for VMware either). We're now way off base from the original post. Besides, this is a Fedora forum as opposed to a VMware or Oracle one. But You're going to be very hard pressed to prove that, as a practical matter, you're better off virtualizing Oracle databases on OVM as compared to VMware.

I never implied other > hypervisors were certified. Not completely true. I specifically suggested Vbox as a recommended alternative given the choices listed by the OP. I then pointed out that ESX/ESXi is a better choice than the three offered. But it is true that I would not recommend OVM either despite the ...ummm "certification" from Oracle.
