Host: Windows 7 Ultimate x64 / Guest: Windows 7 Ultimate x64 / Both systems fully patched.
I had switched my KVM to another machine. When I switched bact to the one VB was running on I saw a dialog box that said a critical error has occured while running the virtual machine and the machine execution has been stopped. It said to press OK to power off the machine but when I did that nothing happened -- the VM just sat there. Fortunately, it was maximized but not in full screen mode so I was able to kill it with Task Manager.
The only application running on the VM was Microsoft Access 2007 in maximized mode with a database open but inactive.
I have attached the log file and the image file. Please note that the image file was editted to remove proprietary information.
I also have the files that Windows creates to be sent to Microsoft when you half to kill an application with Task Manager. However, the zipped file is 765K so I will only upload it if someone ask for it.
