Symptoms: When this happens, all VBox processes becoming zombie processes without ability to get them killed. Windows Task manager did not help -- it refuses to kill VBox processes. I could not soft-restart or soft-shutdown host Windows either. Had to do hard-reset. When I press ""kill task"" in Task manager, the VM's GUI window disappears from Windows Desktop, but process continues to exist in Task Manager. (which I interpret as zombie process) Host OS & all apps continue to run, but becoming extremely slow, especially on Disk I/O operations. Host: Windows XP SP2, Intel Core 2 Q6600 CPU, VBox 2.2.2. (VT-x enabled) It happened with the following combos: (two VMs installed in parallel) * Win2000 + Win 7 RC1 (32-bit) * Fedora 9 and 10 (both 32-bit) I don't see anything strange in VBox logs. But my understanding of them is imperfect. -Technologov, 18.5.2009.",defect,closed,VMM,VirtualBox 2.2.2,fixed,,,other,Windows
