here we have to tell a very important question, if I accidentally put my virtual machine play "Hang Up" later,rebootlater found,virtual machines are starting to come. Re-install the trouble, yes.~what to do now. Haha, the following method can help careless "hand-mutilated" small pots of friends~650) this.width=650; "src=" Http://img.baidu.com/hi/jx2/j_0082.gif "alt=" j_0082.gif "/>

Similarly, this virtual machine snapshot can also be written Shell script, easy and quick to use it yo ~650) this.width=650; "src=" Http://img.baidu.com/hi/jx2/j_0078.gif "alt=" j_0078.gif "/>
