Observations & Suggestions
Let me start off by saying that this is an awesome product that continues to improve by leaps and bounds! Too bad more software companies are not more like your's!
Note: Feedback based primarily on XPSP2 unless otherwise noted (I also have Fedora & Ubuntu Linux VMs).
Using "Exit application on VM shutdown" with Auto-run Enabled
I selected the option to close the "Exit application on VM shutdown" plus I also have the VM set to auto-run so now I can't make any changes to the VM settings since I'm in a cycle where changes can't be made with the VM running but if I close it it completely closes and when I open it auto-runs. Any way around this?
It might be nice to have a setting to not allow auto-run if the auto exit is selected and vice versa unless you make other program changes such as the ability to change the settings and apply to the VM when restarted.
Numbers & related keys will not work on the Mac Numeric Keypad
This is probably more of a wish list item rather than a program issue. Your website states the following, "Keyboard support â€“ use all of the keys on your Mac keyboard, such as the eject CD button, right-left and Shift/Ctrl/Alt (option)/Windows keys, in any virtual machine" (URL= http://www.parallels.com/en/products/desktop/), however, the actual number & math function keys do not work on the 10-key pad of my Apple Wireless Keyboard (only the upper most keys Volume Up/Down, Mute, and Eject). This is very ackward in numeric intensive apps like Excel, Money and others.
USB devices will not work
My iMac's built-in iSight shows in the list but I always get the "wait 5-10 seconds" message even when no other program is using the camera.
Also, I always get a "Device removal" error dialogue when trying to activate my external USB HD. Then Windows XP shows that the device was found but I can't see it in My Computer and it doesn't seem to be available anywhere such as Save As dialogues, etc. Once fixed, it would be nice if the external HD & iSight were automatically available to the VM rather than having to reactivate them each time.
No sound in Fedora Linux
This may be an issue with the OS rather than the VM but no sounds will play in Fedora Linux but they do with Ubuntu Linux and of course Win XPSP2.
VM does not go back to the Property Sheet Screen after Fedora Linux is Shutdown
The screen remains unchangeds after the system halt commands and does not return to the Properties Sheet screen as after shutting down Windows.
Ubuntu Linux will not boot after upgrading to Parallels Beta 3036
OS loading stops with a kernal panic. I will attempt to recreate this VM to see if that resolves the issue (I don't have any data or programs that would be missed).
Parallels Tools for all OS VMs
Apply the Windows VM features to other VMs such as Linux. I would love to be able to have the Parallels Tools features available in Linux e.g. moving from Linux without have to release the window, copy & paste features, etc.
Save VM without Changes
It would also be nice to "borrow" the Microsoft Virtual PC feature to "save without changes". This could be helpful if testing software.especially since the Windows System Restore is deactivated by a group policy (granted System Restore is not the best way to undo something).
Mac OS VMs
Would be nice to also be able to run Mac OS in a VM. This would be good if you wanted multiple OS versions on the same machine without having to have separate partitions and having to boot into another OS. I know Windows folks that use Microsoft Virtual PC to run multiple instances of Windows or multiple OS versions that benefit greatly so why not with Mac OS?
