    <p>I need to detect whether my application is running within a virtualized OS instance or not.</p> <p>I've found <A HREF="http://www.codeproject.com/KB/system/VmDetect.aspx" rel="noreferrer">an article</A> with some useful information on the topic. The same article appears in multiple places, I'm unsure of the original source. <A HREF="http://www.vmware.com/" rel="noreferrer">VMware</A> implements a particular invalid x86 instruction to return information about itself, while <A HREF="http://www.microsoft.com/windows/products/winfamily/virtualpc/default.mspx" rel="noreferrer">VirtualPC</A> uses a magic number and I/O port with an IN instruction.</p> <p>This is workable, but appears to be undocumented behavior in both cases. I suppose a future release of VMWare or VirtualPC might change the mechanism. Is there a better way? Is there a supported mechanism for either product?</p> <p>Similarly, is there a way to detect <A HREF="http://www.xen.org/" rel="noreferrer">Xen</A> or <A HREF="http://www.virtualbox.org/" rel="noreferrer">VirtualBox</A>?</p> <p>I'm not concerned about cases where the platform is deliberately trying to hide itself. For example, honeypots use virtualization but sometimes obscure the mechanisms that malware would use to detect it. I don't care that my app would think it is not virtualized in these honeypots, I'm just looking for a "best effort" solution.</p> <p>The application is mostly Java, though I'm expecting to use native code plus JNI for this particular function. Windows XP/Vista support is most important, though the mechanisms described in the referenced article are generic features of x86 and don't rely on any particular OS facility.</p>

    1. COThere is no reliable way to determine when running in a virtualized environment. I have details including source code on RedPill, NoPill, Scoopy Doo, Jerry, DMI, OUI, ...all of the popular "techniques" and why they don't work here: http://charette.no-ip.com:81/programming/2009-12-30_Virtualization/index.html

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
