We currently have XRY running on a VMware Player running XP on our W7 computers.
I tried this recently (I think it was XRY 5.1 or 5.2, though), and I had issues getting dongles/phones to show up in the VMWare player, and for whatever reason I could only get things working adequately with the latest full version VMWare Workstation. I also tried VirtualBox hosted on OSX and Windows 7 (similar results)
Did you run into any of these problems? If so, how did you solve them?
We did have this as issue to start with until I realized that you have to insert your usb device (dongle, phone etc) whilst your VMware machine is the active window on your computer. It will then (sometimes a little slowly) capture newly inserted usb devices automatically.
This means that you will have insert your dongle each time you start your VMware computer for it to be captured. Its a bit of a pain (because I like stuff to just work) but does seem stable and consistent even with all the 32bit drivers for mobile phones that I've tried it with so far.
It's been a while since I tried to use it in a VM, so I can't remember exactly what was going on - I'm sure I tried this, and couldn't get it to work. Could just be my bad memory…
I also tried recently and had the same issues of dongles / phones not showing up. It is also a little worrying running XRY in a VM as, unlike software in a VM, Physical USB devices are not sandboxed completely from the host machine, so you may inadvertantly end up connecting to the wrong machine either by mistake or automatically after a system crash (windows update etc). This may have implications to your evidence.
I ended up loading XRY onto a netbook running 32-bit win7. It fits perfectly in the case and is really handy for going out in the field because you don't tie up a valuable laptop, just a little dedicated netbook.
At work, I currently use Windows Server 2003 64-bit. I have tested .XRY 5.3 running in a VMware running WinXP 32-bit. I have noticed zero difference between the VM and another machine running a 32-bit OS.
