You might get this message when the virtual machine you’re opening is out of disk space or at least it thinks it is.
The file system upon which ‘~/VMware/Windows XP Professional – SP3′ resides is critically low on free space. Allowing this virtual machine to continue may cause it to fail unexpectedly. VMware Workstation has paused this virtual machine because the disk on which the virtual machine is stored is almost full. To continue, free up at least 495.2 MB of disk space.
When booting you’ll get stuck in an endless loop. To ignore the above warning and be able to start again add the line below to your (Windows XP Professional).vmx file.
