Also, if the computer is turned off, does it take any resources?

Thanks in advance

BTW: I already searched the web for this - no result :(

What sort of resources? Disk space? RAM? CPU? Network? – Smudge Dec 7 '11 at 11:24
Any detail possible will be helpful – Yacov Dec 7 '11 at 16:49

In pause mode, the VM is not actually suspended--rather, processor execution is literally stopped at whatever point it was in. So the machine itself is still in memory, and the allocated resources are still allocated to the VM process on the host. This is entirely on the VM side--this isn't handled by the guest OS.

In suspend mode, the contents of the RAM (as used by the VM) are copied to disk on the host, and the machine itself is suspended--which means that except for the additional disk space caused by the storing of the RAM to disk, there's absolutely no additional resource usage. Any temporary resources requested by the VM while running are stored to disk and will be re-allocated when the machine is restored.

+1 Thanks - Just to clarify, What the meaning of Pause\Suspend mode – Yacov Dec 7 '11 at 17:03
Pause halts execution and is usually specific to a VM (since this happens at the pseudo-hardware level). Suspend will shutdown all components, providing energy to the RAM (which is temporary and is lost when power is turned off). Those are their definitions, in this context. – Andrew M.
