Thanks for clarification. I think I did not differentiate the two words as well. >> 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.

Oh, I did not know that. >> (BTW: Is Oracle DB supported in a Oracle VirtualBox?) > > Yes, for development and test purposes.

But I am actually not that sure how much it matters. As I was "toying" with Oracle VM I moved a Zimbra Server running on Ubuntu. From FreeBSD/VirtualBox to Oracle VM (Linux/Xen) I did not "feel" a difference. Maybe a benchmark question: Which benchmarks would you run to compare the two in various ways? If I have a bit time I like to try it. I find it difficult to compare them in "normal usage" if you do not migrate all VMs from one solution to another (on the same hardware) because the overall load of a system has an impact on a VM as well. I also tend to have a bit of "space" on the servers to avoid bottlenecks. Usually I do not over-allocate (sorry, there is a better word I just cannot remember just now) or at least not much. The space is also used as a buffer if I have to migrate VMs/services suddenly (e.g. caused by a failing machine) The result may differ on different hardware as well. E.g. I could imagine to have different results if I try the two stacks on a 32GB modern hardware - or on a 5 years old machine with 8 GB only. Depends where I find a bottleneck. > Hope that makes things a little clearer from our perspective. Yes it does:-) Thanks Peter _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
