1. Cut a part of sxxx.vmdk file to another drive letter: Open Debian_Lenny.vmdk with ultraEdit, and you will see a file list, relocate the cut file and start the virtual machine.
2. Install vmware-tools in linux, and execute strike with root in vmware-toolbox: Ensure that the space of the current disk is greater than or equal to the size of the virtual machine to be attacked. If the current disk space is not enough, you can move some files to other disks by the first method mentioned above, then strike, and finally move the moved files back.
