I'm attempting to make several test machines virtual. Ideally I'd like to setup several images with various installed software - eg. windows 7 with quickbooks 2010, vista with quickbooks 2009, etc - save the images, then restart them later as needed on other hosts.

My question is: will I run into licensing issues? I own licenses for all the software so I'm no worried about whether this is permitted or not, I'm asking if practically I will run into issues with software refusing to run for any reason.

Haven't decided between xen/vmware/virtualbox for the virtualization environment, if that makes any difference.

in its simplest form the windows guests will run fine but there may be name collision issues. – tony roth Jul 26 '10 at 18:39
Most will not notice the different host (though they will likely notice the different MAC address, it's usually not a problem). Licenses generally don't care, but you might double check the exact license text. Licensing has gotten a little fuzzy, the old licenses especially which state that you can install the software on one machine (where they really mean you can install the software once on a copy of Windows). Sometimes the companies have updates license agreements you can switch to. – Chris S Jul 26 '10 at 18:48

You shouldn't have a problem. The virtual machine doesn't have any idea what physical machine it is running on, so it shouldn't know that the hardware under it has changed.

mrdenny is right on. If you are going to be running the clones on the same network, I would suggest changing the hostname and IP. :D – JakeRobinson Jul 31 '10 at 5:50

You may run into problems with the machine SID if you run multiple VM's simultaneously, especially if the VM's are joined to a domain.

This is not specifically a license problem, though. It's not that hard to change the a Machine SID, using something like sysprep.

Duplicate SID issues are a myth.… – JakeRobinson Jul 31 '10 at 5:47
