Why HyperV and ESXi start when the virtual machine, machine tool disk space should be reduced? Virtual memory should be deposit in the virtual machine.
For example, the Hyper - V virtual an 8 gb of memory (not dynamic memory) Win2008R2, didn't start the virtual machine, if the machine tool and 50 gb disk, but a start the virtual machine, 50 gb would be reduced. Why is this? Theory, even if this Win2008R2 virtual machine enabled pagefile. Sys, it is also written in the book of the virtual machine in the virtual disk, should be the first time you start it is occupied, but why now every boot, the mothership also reduces disk space? And when the virtual organ after closed, will be released back to the disk space (that is, back to 50 gb). This is precisely what happened?

Sorry, because of my personal ability is limited, can't help you,

he has a memory file,

Give priority to use virtual machine program host memory, free will synchronize the file,

The function of the file, I, for example:
When you use the saved state, if there is no this file, you need to dump the whole memory,
Now you only need to be synchronized part difference,

So you will find saving state will soon,

I didn't noticed this kind of situation,

But the virtual machine physical memory, the memory is not completely in machine tools in the application, the virtual machine the memory physical memory can be greater than machine tools, so the virtual machine will use other storage space, the disk such as machine tools,
