I have to admit not really to understand the "support this or that virtualisation"
A virtualisation presents a "virtual computer" and this may slightly differ depending on the virtualisation solution.
But the same goes for physical machines.
And I have not read: "Product XY only works on Dell T610 and HP ML 150". I can install it on a "no name box" as well. Why not on any VM?
The ERP solution [not Oracle, btw] I am dealing with in-house runs on Tomcat. Tomcat and Java are designed to live "everywhere".
Of course the software is certified on Linux X and Windows Y only..
So, in theory virtualisation should be roughly the same everywhere. And something like the JVM is designed to work almost everywhere. And usually it all works OK. However sometimes you get bizarre incompatibilities -- the one I'm thinking of is OpenVZ and the JVM. I don't know why, but the jvm just doesn't work right under OpenVZ -- it's a well-known issue. (And one which I believe points out that openvz has been flawed all along; I wouldn't trust *anything* under it as a result) Anyway, given such occurrences exist, I could see why software vendors might not approve of their stuff being run in certain VMs. If they've found it causes support headaches, they might just not want to go there any more.
