1. Snapshots
A snapshot is a mirror image of a full system at a point in time on a virtual machine that can be recovered from a snapshot file inside a virtual machine to a previous node.
Take a snapshot:
To recover a snapshot:
2. Cloning
A clone is a copy of the entire state of the original virtual machine and is isolated from the original virtual machine, creating a completely independent virtual machine on the host or other machine by cloning the file.
3. Virtual Machine Disk

Since some customers ' business systems run on 2003 for many years, even after migrating to virtualization, still do not want to replace the operating system, Windows 2003 is not as easy as 2008 or 2012 of the operating system on the expansion of the disk, the direct expansion of the volume point two under the mouse can be.I saw some friends in the morning.

PE Knowledge Review PE expanded festival One, why expand the FestivalAs we said above, the blank area adds our code. But sometimes we don't have enough space to do it. Therefore, the expansion section is needed.The expansion of the festival is actually very simple. Modify the size of the section data to be aligned. and add 0 data to the PE file to fill.First Look at our section table.typedefstruct_image_sec
Description given a forward graph, each edge has a capacity of C and an expansion fee of W. The expansion fee here refers to the cost of expanding the capacity by 1. 1, in the case of no expansion, the maximum flow of 1 to N, 2, the maximum flow of 1 to n increases the minimum cost of expansion required by K.

Many people do not know what the expansion disk means! In fact, the expansion disk refers to the use of related software to allow a small volume of u disk on the computer display a large capacity (such as 512M 2G). However, more out of the memory is not normal use, the U disk deposited in the file as long as the actual capacity of more than the copy will be damaged (available installation files become una

How to implement tree-level catalog folding and unwinding1 IntroductionRecently has been writing projects with Swift, has now completed the half, probably in mid-November can be completed, the time will be a series of video, the source is stacked out. I am the iOS 0 Foundation learning Swift, which has not had any OBJC experience in the past few weeks and has been spent in the cycle of pit crawls. At present, not only the swift Chinese information is scarce, the English material is very few, man

Title effect: Given an n-integral m without a graph edge, each party has an extended cost of C. Represents expansion of 1 of the cost of traffic, seeking maximum flow and extended maximum flow K minimum costFirst ask the maximum traffic that runs directlyThe second problem will be that the starting point of each edge connected to the end of a stream is the positive infinity, the cost C-margin, and then the N-sinks are connected to the flow ans+k cost
This article mainly introduces jquery's simple method to implement the expansion and contraction of the webpage layer. it involves some techniques related to the use of toggle in jquery to operate the page element attributes using the animate method, which is very simple and practical, for more information about jquery, see the following example. Share it with you for your reference. The details are as follows:

In jquery, we will use the toggle () method to scale down the expansion effect. Next I will show you two jquery-based code for scale-down and expansion, hoping to help you.
The main code is just that. This is just a simple special effect. In the future, it can be derived from a lot of complicated features. for front-end development, you need to explore it yourself and start more.
