Virtual machines run faster in full screen mode. Cutting, Copying and Pasting When VMware Tools is running in a virtual machine, you can cut or copy then paste text between applications in the virtual machine and the host computer or between two virtual machines. Just use your host or guest operating system's cut, copy and paste commands. Make sure you installed and started VMware Tools in your virtual machine. In a Windows guest operating system, you will see the VMware Tools icon in the system tray when VMware Tools is running.
Persistent disks behave exactly like conventional disk drives on a computer.
All data written to a persistent disk is written out permanently to the disk as soon as the guest operating system writes the data. All changes to a nonpersistent mode disk are discarded after that virtual machine is powered down. When you use undoable mode, you have the option later of keeping or discarding changes you have made during a working session. Until you decide, the changes are saved in a redo-log file. You can use the Configuration Editor to change the disk mode for your virtual machine.
