Hi, Every few minutes the guest XP OS running on Parallels for Windows 7 (x64 version of Win 7) stops and I get a dialog box saying there isn't enough free disk space to run the VM - however, there are 155GB of free space on the drive on which the VM is hosted, and the disk of the guest XP OS has 2.5 GB free. Can anyone explain why the error pops up and how to get rid of it? Here are the details - Free space on the drive=D:/Parallels - 2011-12-29/Gordon's XP.pvm necessary to run the virtual machine: 143 MB. Current free space on the drive(D:/Parallels - 2011-12-29/Gordon's XP.pvm): 0 MB. - Gordon
