The official line from Oracle regarding VMware is: if you run Oracle in VMware, we won't support you except for problems which are known to occur *outside* of a virtualisation environment. In short, we'll support you to the extent that you're not really very virtual.

I love VMware and have been a keen advocate of it in a learning environment since 2000 -but you wouldn't get me to install Oracle on a virtualised platform in *production* unless I'd had a frontal lobotomy that morning. EMC do a very good line advocating the use of virtualised Oracle with their SANs, but then they would say that, wouldn't they?! Frankly, it's just a bit of a no-no because of the support issues. Of course, Oracle have their own Xen-based virtualisation offering now, and it will be interesting to see to what extent they will support that and how far into other virtualisation environments that support level spills. But right now, I wouldn't touch it with a bargepole. Not because it runs badly or flakes out (it generally doesn't) but simply because if anything at all goes wrong, Oracle Support will be blaming everything they can on the virtualisation and you'll get no resolution of anything meaningful this side of the average human lifespan.
