What VM do you use, and on what Linux?
We went to Redhat recently, b/c Oracle will support the OS. We'd been having a lot of OS-related problems with Oracle on W2KServer. And, of course, we're all partial to *nix.
But, we've got some .NET apps that I'd rather not have to port, and at least some of them I want to run local to the DB
While I know that Mono is not yet mature, have you tried looking at that for your .net apps? They may run fine on Mono. They may not, and you may have to resort to a VM solution for a while.
