Vmware Tutorial - Part I
Now many people have computers, but most people are only one or two, I would like to form a local area network or their own small-scale experiments to be a machine is not enough, at least a two or three units can be for this too much worth to buy a computer. Fortunately, there are many virtual machines can help us solve this problem. Virtual machine can be in a virtual computer on a lot of the host, as long as the true configuration of the host can be enough, I here to talk about one of the other veteran virtual machine VMware.
VMware workstation is designed for professional VMware virtual machine, any existing operating system can be virtual, but the use of simple, easy to use. Microsoft employees have to know all the machines are equipped with a genuine copy of VMware, shows its authority in this respect, nonsense talk, I talk about everyone on the combined use of VMware, I'm using the latest VMware4.
The software installation and no difference between other software, the installation process so I will not elaborate, and the following I will use VMware complete process is divided into: the creation of a new virtual machine, configure a virtual machine installed, configure the virtual This is the network machine in three parts, to say to you from scratch.
First, create a new virtual machine
First of all, let us look at the VMware interface
We have to create a new virtual machine
Choice of general or custom installation. Here we selected from the definition of the planning behind their own equipment, memory and hard disk capacity
Select the desired virtual system
to the virtual machine, specify its location
Allocate memory size
Network configuration mode. More complicated here, the installation time could be a random selection, can also be installed after the change, but do not the last elections, otherwise, you will not be able to create a network. With regard to the distinction between these three and how to use the virtual machine to connect to the internet will be introduced later.
To create a disk. When the establishment of a virtual machine the first time, please choose the first one, the second for a second or more virtual machine, which has established a good use of virtual machine disk, thus reducing the actual virtual machine disk space occupied. The third virtual machine is allowed to directly read and write disk space, more dangerous, so familiar with the use of disk for the advanced user, if the true error will be the contents of the disk where deleted.
Set up virtual machine disk capacity. The first disk size can be defined. The second virtual machine to allow unlimited use of disk space, but the real disk is large enough. They are restricted in the third of each virtual disk to the maximum capacity of 2G.
This step is the final step, the virtual disk is about to be created, advanced you can change the virtual disk is a SCSI interface, or IDE, of course, SCSI you ...
Has been established at this time completed a virtual machine, and click the Start button to run, but the kind of system in a virtual machine do not, you still own loading.
This part of the following equipment I could use a windows2000 professional give you a good demonstration, mainly explain some of the features we used
Switch machine so I do not explain how, and try to know.
This feature is interesting, is 4 years new, a bit like XP's System Restore, if you do in a virtual machine on what led to it hung up, this can be restored, but each virtual machine can only have a snapshot point.
Bahrain's system just does not like me as so beautiful, you have not installed this driver, but you thought of VMware, you do not have any drivers installed, only need to run the map in that thing
Installed to see this after the virtual machine's hardware state will find all of the hardware are working properly, but in fact true as long as your system hardware drivers are installed, VMware virtual machine will be installed also. End, the installation of virtual machine has been completed, the second part of the following.
VMware Tutorial - Part II
Second, configure a virtual machine installed
What I mean by configuration, that is good has already been installed on the virtual machine memory capacity, hard drive size and the number of modifications, such as network type, so it is easy to "change" needs a lot of
Will appear after clicking a specific set of equipment can be changed.
Add a device also containing simple, as long as you can add, add just the beginning of the process to configure the installation process as the virtual machine.
Need to share folder to mention this feature, this is a new feature VMware4 is the real host in order to share files more convenient to set the time, it will add a mechanism in a virtual share folder named disk, drive letter for the Z, is very simple to add up, click on the add, select a folder it can host. This feature is in bridge mode can visit UNC name in lieu of, however, NAT and host only mode, this feature becomes very useful, because these two models in the direct use of IP addresses has become very difficult. Finally, the following would also like to remind that in win98 (included below) of the system can not support the Shared Folder feature
The next article, we will introduce "virtual machine's network configuration"
VMware Tutorial - Part III
Third, configure the virtual machine's network
Having a virtual machine is not enough, we need to use a true virtual machine and host and other virtual machine to communicate. Communication is divided into two parts, one is the LAN, and the other is connected to the public network. This part is the focus of the use of three different models will be announced.
(1) bridging mode:
If you are a true host in an Ethernet, this method is to access your virtual machine The simplest way to network. Virtual machine is like a new, and the real host has the same physical status of a computer, bridge mode can enjoy all available services; including file services, print services, etc., and in this mode you will be the easiest access to the host from the real resources.
Host-only mode used to create isolated virtual machine environment, which this mode, the virtual machine host and the real through the virtual private network connection, only the same Host-only mode and a virtual switch in the connection is only possible with each visit, do not have access to the outside world. host only mode can only use private IP, IP, gateway, DNS to distribute by VMnet 1.
(3) NAT mode:
NAT (network address translation) mode can be understood as a matter of fact it is convenient to make the virtual machine to connect to public networks, the cost of bridge mode can not access other features. NAT structure of any selected virtual machine, VMnet 8 provided by the IP, gateway, DNS.
Talk about the specific operation of the following.
I have already mentioned the front, bridge mode is the simplest to use bridge mode the host virtual machine and the real relation between the two seemed to take in a hub on the computer, they want them to communicate, you need to configure both sides IP address and subnet mask, can be seen from the chart, if you do not configure the virtual machine, virtual machine has no way to get the DHCP assigned IP address, so can only use 169.254. this paragraph. Some of my friends have tried to change in the real host in the VM after the installation and VMnet1 generated two network card VMnet8 this IP, this approach is wrong, as the underlying hardware to connect the driver they do not need and can not be revised.
On the assumption that the real host of the IP address of network card is configured to 192.168 of the network segment, the virtual machine must match the IP of the network segment 192.168, this virtual machine can communicate with the host and real. If you want to bridge mode connected to the internet, is also very simple method, you can directly in the virtual machine to install a dial-up client, as shown
Dial-up after the success of the internet more than you can, do not think that a virtual machine on a dial-up is false is false, and this time you have spent a net cost! Of course, if you want to pass the ICS, NAT or proxy can access, practices, and in general do not distinguish between computers.
Host only mode:
Host only mode and bridge mode is not the difference, host only mode VMnet 1 from the DHCP server to provide IP, gateway, DNS.
If you try to use the manual allocation of a fixed IP, you will find the IP address even if you are a true match and a segment host, you can not contact the host and real, this is your VMnet 1 restrictions, the use of VMnet 1 to provide you with the IP is the only option.
If you want to host only mode you can only access internet using ICS and agents, because the only two ways
DHCP in the case of the use of the Internet.
VMware first we need to clearly under Windows NT in NAT and routing and remote access point NAT relationship that did not, they are not in any way. VMware to use NAT in the mode of the main advantages of virtual machine to hide the topology and on the internet when convenient. NAT mode VMnet 8 from the DHCP server to provide IP, gateway, DNS.
And in the same host only mode, if you try to use manual allocation of a fixed IP, as a result of the restrictions VMnet 8, you still can not communicate with the host and real. However, in NAT mode, internet access is very simple, you do not need to do any configuration, only the real host to connect to the internet after the virtual machine can access on the internet.
VMware's NAT function also more than these, it even can do port mapping and the TCP, UDP blocked!
Do not think it lacking something? Yes, there is an important function also did not say that the reason to stay to the end because it is the most complex, and that is ...
Virtual network settings
This part of the function I think in general the user has less than, because its role is to use VM's highly scalable network model the formation of very complex network, I believe this is the essence of the new VMware host.
This is VMware's an example of a complex topology, it has been custom VMnet 2 and VMnet 3 should be used in the definition of each of these VMnet of DHCP and NAT, as long as it is very complicated, and do so only in very large virtual cluster when the only used to be.
Well, the introduction of VMware on this, if you good in English, then help in its far deep you will find the contents of this article, in fact, as a virtual machine software, it has been brought to us by not only to a single virtual system, but to a large and complex virtual networks, this article only touched fur. Of course, if everyone is very concerned about the functions of VMware deeper, then I am also very willing to discuss this with you.
