1. Manage vsphere

I used vmware workstation 7.1 to install ESX Server 4.1. for testing purposes only, the actual production environment should be deployed on dedicated servers:

To manage the ESX Server, you also need to install the vsphere client. After installation, enter the ESX Server IP address, user name, and password to log on:

The ESX-Win2003 is a virtual machine installed in a virtual machine that supports direct installation in ESX Server 4.1 and requires modifications to the vmx configuration file in previous versions.

The Management Console is similar to hyper-V and is easy to use:

 

1. Use vsphere Java API to manage ESX

VMware provides a large number of APIs to manage its products and supports Java, C #, Perl, and other languages. Here I use the vsphere Java API for testing.HereDownload. (C # API documentation and examples are incomplete. I tried to compile them and encountered many errors. I will try again later)

3.1 open eclipse and create a project:

Add the downloaded jar package of vsphere Java API to build path.

Code Package Brooks. chapter5.simpledemo;

Import Java.net. url;
Import Com. VMware. vim25.virtualmachinecapability;
Import Com. VMware. vim25.virtualmachineconfiginfo;
Import Com.vmware.vim25.mo. folder;
Import Com.vmware.vim25.mo. inventorynavigator;
Import Com.vmware.vim25.mo. managedentity;
Import Com.vmware.vim25.mo. serviceinstance;
Import Com.vmware.vim25.mo. virtualmachine;
Import Com.vmware.vim25.mo. util. commandlineparser;
Import Com.vmware.vim25.mo. util. optionspec;

Public ClassHellovi {

/**
* @ Param ARGs
*/
Public   Static   Void Main (string [] ARGs ){
Try {
Commandlineparser CLP =   New Commandlineparser ( New Optionspec [] {},
ARGs );
String urlstr = CLP. get_option ( " URL " );
String Username = CLP. get_option ( " Username " );
String Password = CLP. get_option ( " Password " );
Serviceinstance Si =   New Serviceinstance ( New URL (urlstr), username,
Password, True );
Folder rootfolder = Si. getrootfolder ();
Managedentity [] mes =   New Inventorynavigator (rootfolder)
. Searchmanagedentities ( " Virtualmachine " );
If (Mes =   Null   | Mes. Length =   0 ){
Si. getserverconnection (). logout ();
Return ;
}
Virtualmachine VM = (Virtualmachine) mes [ 0 ];
Virtualmachineconfiginfo vminfo = VM. getconfig ();
Virtualmachinecapability VMC = VM. getcapability ();
System. Out. println ( " Hello: "   + VM. getname ());
System. Out. println ( " Guestos: "   + Vminfo. getguestfullname ());
System. Out. println ( " Multiple snapshot supported: "
+ VMC. ismultiplesnapshotssupported ());
Si. getserverconnection (). logout ();
} Catch (Exception ex ){
Ex. printstacktrace ();
}
}
}

 

3.3 configure command line parameters: -- URL https: // 192.168.200.htm/SDK -- username root -- password ******(Replace your own esx ip address, user name, and password.)

 

3.4 The running result is as follows:

 

1. Use powershell to manage ESX instances

VMware provides the extended vsphere powercli of powershell to facilitate management of ESX/esxi and so on.HereTo download the SDK, you must register it first.

4.1 After the download and installation, the command line interface is as follows:

 

4.2 to make it easier to use powershell, we use powergui Script Editor free Editon to compile powershell.HereDownload. It supports breakpoint debugging and powerful intelligent sensing.

To use the VMware powercli extension in the powergui Script Editor, you must first import:

Add-pssnapin
VMware. vimautomation. Core

 

Use connect-viserver to connect to ESX and start-VM to open an installed virtual machine:

If you use HTTP to connect to ESX, an error occurs. We recommend that you use HTTPS.

 

1. Summary

with more and more application of virtualization technology in enterprises, the requirements for virtualization technology are also increasing, starting with the most basic Code and script, we have a basic understanding of the VMware vsphere 4.1 platform, some simple management operations are performed. The virtualization technology solution is very complex and involves a wide range of technical aspects. I also conducted tests with a research attitude. In the future, I will also focus on other virtualization solutions, for example, Microsoft's hyper-V and Oracle's virtualbox are combined with the corresponding SDK for some tests.
