Is there an official way for an application to determine if it is running in VMWare or Virtual PC (or whatever Microsoft is calling it now)? The code I have seen is usually a hack that took advantage of some odd behavioral side effect in a specific version of VMWare or Virtual PC.
Ideally Delphi code, but if you can link to an official explanation then I am sure I can convert it.
I wrote a series of articles last year on this, with source code. VMware and Wine detection are here. Virtual PC is here. All three of these have pretty iron-clad detection because there are documented callbacks to the hypervisor (in the case of Wine, an extension to a standard DLL). I put up an untested VirtualBox detector (don’t have it installed to test with) in the comment section. Parallels might be detectable using a callback also but I don’t have it installed. The link for the documentation (which is poor since it’s from a security researcher focusing on exploits) but located here if you have it installed and are interested. There’s also a PPT here that has some information on detecting Sandbox, Bochs, and Xen. Not a lot of code in it but it might give you a starting point if you have to detect those.
