1-vmware Workstation know

VMware workstation is familiar with a virtual software, we can be very convenient to virtual a lot of virtual machines, to facilitate our testing and learning.

Before you create a virtual machine, you must understand two concepts:

Guest: Virtual Machine

Host: Homestay

We create a virtual machine that is primarily created CPU,MEMORY,I/O (Disk,ethercard).

1, our pc on a CPU, that has more than one virtual machine running at the same time, how does the CPU work? CPU is the use of time-sharing system work, a period as a few pieces of time, if the 5ms for a piece of time, the first piece of time to Guest1, the second piece to Guest2 ... This will ensure that each virtual machine has CPU usage.

2, memory, logically divided into several pieces, assigned to each virtual machine.

3, through the virtual software can be virtual out of keyboard and Ethercard.

4, the hard disk, vwware the disk image file: Disc images files. When a file is used as a disk, a disk controller is generated by a virtual interface, which makes a file look like a disk and can specify its size.

VMware's disk is in sparse: sparse format, where the virtual machine capacity shown on the host is the actual size of the virtual machine, not the size of the hard disk set by the virtual machine. If the virtual machine generates a 120G hard disk, it only occupies 5G of capacity on the host.

There are 3 main types of network in VMware workstations:

in theVMware Workstation, the default is3virtual switches, respectively, areVMnet0(using bridged networks),VMnet1(Host network only) andVMnet8(NATnetwork), select a different network type, and you will be connected to a different virtual switch.

1, bridge Network:

Figure E1,e2,e3 represents the guest's network card, E4 represents the host's network card.

Bridge Network mode is the guest's network card through the virtual Switch VMnet0 sent to the host network card, the host network card and the outside world to communicate. At this point all the guest is equivalent to a separate computer on the network, with a separate I

2. Host-only mode network

E5 is a virtual network card, in host mode, guest and HOST1 can access each other, but cannot access HOST2, HOST3

3. Network address translation (NAT)

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M00/7A/25/wKioL1ajcpPysCkQAAA2UnEAxC0653.png "title=" 3- Nat.png "alt=" Wkiol1ajcppysckqaaa2uneaxc0653.png "/>

In NAT mode, guest on host can access host2,host3 one-way, but HOST2 and HOST3 cannot access guest on HOST1

Mechanical hard disk: partition is to put some of the tracks next to each other, 0 track is from the outer ring, the speed is fixed, the computer hard disk reading data closer to the outside of the track line speed, c area is the most outside so C zone read the fastest, followed by d,e,f ...

So if the usual data should be saved in C,d,e, the front of these several disks, so that the reading is relatively fast. So our virtual machines are best saved in the c,d disk so it reads faster.
