P2V (physical to virtual), which stands tools and plugins that are available to move images from one physical host to a virtual host describes.
Lets first understand the nomenclature:
"Physical" refers to the hardware (computer / server box) environment. This is the "traditional" and the method used to provide server services / resources for the network. "Virtual" refers to the environment that was created by a virtual software, and is able to support / hostmultiple instances of an operating system / s. So, if you will, the physics is probably what you have and the virtual, is probably where you want to be. How to get where he is coming in the P2V tools and plugins
P2V works to change the physical state of an operating system installed, like a painting. If you used Ghost or Acronis, you'll know what I mean. This image is a compressed file, similar to an ISO. Can be stored or used at any time. It contains allSystem files, drivers and so on, to make it profitable if we have unpacked and installed on another computer or a virtual machine (environment) is required. Images can also be the entire state of a complete operating system and installed applications.
Imaging an operating system is not new. We do this for years. Most workstation rollouts were using Ghost images (probably still are). Microsoft refines the technique of operating system deployment when youintroduced RIS, Remote Installation Service Server /. Unfortunately, some 'limited by the RIS NIC drivers in many areas and do not always work well. RIS uses DHCP (BootP) and DNS to find and provide an operating system on a target computer. P2V is doing just that. But even one step forward, which is taken from a standard image of a physical computer and transforms the image into a virtual machine. P2V can also independent of the virtual servers from one host to anotherthe type of hardware that supports host.
Virtual machines provide an environment similar to the old NTVDM (NT Virtual DOS Machine). The NTVDM tried to create an isolated environment in the architecture of Windows NT, the Board Layer. It will allow 16-bit (DOS) in 32-bit applications running on the Environment, is still in place. The theory was that if the DOS application crashed, because you probably do, there would be other applications or the operating systemSystem with the ground. The application would crash and would NTVDM NTVDM subsystem in the event of Win32 content, and do not allow access to hardware (microkernel). This is not always as it should, and usually led to the infamous blue screen. Fortunately, things are a little 'more stable on Windows before, and it shows less blue screens, but to serve us.
In a virtualized environment is the key to efficiency and success is being able to easily manage the entireInfrastructure without too many restarts and downtime. In a traditional infrastructure downtime / physical inevitable if management is implemented effectively. Updated when moved in a physical infrastructure, it is necessary that the new servers are installed, shut down the old server and existing or moved, etc., is going to happen over time, what ever do to try to avoid them. In this scenario, there is a case to limit the damage and try to do the work if the network"Quiet." Virtualization can allow all these activities without excessive interruptions. P2V tools are for creating and managing the virtual enterprise.
P2V lets you switch from pre-operational server (with applications), an environment based on hardware in a virtual environment. This activity can occur when the network is used. But how do you inject with a large photo across the LAN or WAN, is a good idea to choose a quietPeriod, instead of in the middle of the workday, or when fired backup systems.
With a virtual machine on the image of a physical host-based operating system has made a number of advantages compared to less downtime. Virtual machines can not access the hardware directly. As the old NTVDM, there is a "vacuum" between the VM and the hardware. This may be occupied by a hypervisor or operating system that was installed as a virtual host. VMwareinstall a virtual host. This is a modified Linux kernel. Microsoft Virtual Server is installed on an existing Windows operating system. Other virtual instruments directly on the metal, how to install Xen and XenEnterprise. Virtuozzo uses a different approach to virtualization. It partitions the operating system. What makes it unique among virtualization tools.
Do not access the hardware in the same way that a traditional operating system, the VM can serve as hosts fora variety of different operating system image. And 'accepted requires the guest operating system, and serve as required. The operating system does not know that it is virtualized. CPU and RAM is the virtual guest operating system, delivered as if the guest has been to install the metal in the traditional way. This means that there are no conflicts, no memory conflicts and no downtime, why not create or replace system files and a reboot is not necessary. And 'onlynecessary for the VM, not reboot the host.
P2V tools to move beyond the operating system (images) are used for the virtual environment from the physical. They can be used for disaster recovery. Images can be stored in an o / s image bank for future use. P2V can be used as a backup tool and as a method or standard / s are used in applications across the enterprise.
** Be careful with P2V as a backup tool for daily backups. Images can be very large, which sharpen yourNetwork to a halt, if not properly planned. Tape is not super-fast recovery gigbytes, but compared to the way a P2V recovery tool, there is a smooth positive .**
The virtual hardware of a virtual machine is always presented from the physical hardware on the original server. P2V migration tools are an easy way for problems to solve in making the switch. The market leader in this segment of PlateSpin and VMware virtualization, but also otherwell-known competitors are present, as Leostream. Here is a list, and some information about some of the tools and plugins P2V, to my knowledge. If you know of others, why not write and we all know.
VMware P2V Assistant:
This is probably the most popular tools for P2V. With this tool, you can drag and drop your photos wherever you need it.
The VMware P2V Assistant copies all files that reside on a source disk to a physical source computer andstores them on a virtual hard disk, also known as a destination. If an operating system is present in the source disk is copied to the destination hard disk. That goal is the new clone. The cloning process requires a P2V Assistant Boot CD, boot the computer and retrieve the source of information to identify the source computer. In addition, the P2V Assistant must be on a computer (physical or virtual) that are not the source computer is running. The resulting clone iscontained in a series of files in vmdk format. This type of clone can be used in VMware GSX Server and VMware Workstation virtual machines.
VMware said that this procedure is complex and the migration from an image from a source to a destination is not a job unattended. VMWare also that the procedure must be performed by competent administrators or technicians, which are carried out by an official VMware P2V Assistant training went. Hmm, not sure. After someMigration of me, I can say that is not a particularly complex task. If you can set up and manage a successful use RIS, you can do this with ease. Could it be that VMWare tries to sell expensive training? I leave you to decide.
VMware P2V supports Windows NT, 2000 and 2003. VMware P2V engine needs third "helper". This can be a physical or virtual machine. You also need a bootable CD. You can P2V to clone or create Ghost, Acronis, PowerQuestCenter Image, or any other imaging tool, you know, and you can use the image in the desired format for VMware P2V.
In my opinion VMware has made this process a little 'harder than it should be. Other tools work the same way, to support a wider range of operating systems that cost much less and do it without an engine to "help". But if you feel comfortable in a Windows environment or in a job, then the instrument is perfectly well and is inexpensive tooperational level in terms of time and money.
Leostream P2V Direct 3.0:
The P2V tool is used with VMware and Microsoft virtualization tools. It is a management interface, but it has some interesting and useful auxiliary functions, which could amiable administrator for the company to a virtualized infrastructure.
The disadvantage is that it works only with Windows operating systems. Because Windows is the dominant center operating system data, at this moment, is not really aRestriction. However, this situation is changing, and Leostream no doubt change with it.
Leostream The system consists of a magician and a host agent that may be on different networks, provided there is a connection routable to the following ports (8080, 9400, 9401 and 9402). The wide area network connections are supported.
The Leostream P2V Assistant is installed directly above the origin of physical servers and is compatible with all 32-bit versions, service packs and allSecurity patches from Microsoft Windows 2000, XP and Server 2003. Support for NT4 service pack 6a and all security patches.
Leostream the host agent is installed on the target host server, the virtualization software.
Leostream P2V Direct installation wizard is run, and not on the source machine-installed without a reboot. You can see the machine in working order so that it can perform all the services and the driver card and determine the changes needed for asuccessful implementation. Then the virtualization layer to create a corresponding virtual machine provides a small operating system and start the VM. The slices are then transferred by copying the existing drivers. Once the disk transfer is completed then the VM is booted into Windows and uninstalled Leostream Wizard automatically. What could be simpler?
There are two versions available, the Windows version is compatible with VMware Workstation 5.x for Windows XP (all service packs)VMware GSX 3.x, VMware, Virtual Server and Microsoft Virtual Server 2005 R2 running on 32 and 64 bit Windows Server 2003 (all service packs). The ESX version is compatible with VMware ESX Server v2.5.x and v3.0.
Leostream argue that it is done once the migration without a reboot. I have not tried yet. If you have, please let me know how it went. Leostream also say that this is a simple process and requires no training (!). Well, it's a blessing.
PlateSpinPowerConvert:
The claim is that the data PlateSpin, operating systems and applications are hosted from servers on which decoupled. This allows you to automatic conversions anywhere anywhere between physical servers, virtual machines and image archives. PlateSpin PowerConvert can be used for server consolidation, disaster recovery, hardware migration and test lab automation, and more are used. You can install server in each direction between physical machines, blade infrastructures for electricity,virtual machines and image archives over the network.
Drag and drop to a physical server or server virtual machine running Windows or Linux will be transformed into fully functional virtual machine on VMware Infrastructure 3 and VMware ESX Server, VMware Server, Microsoft Virtual Server or a PlateSpin Flexible Image Hosted. No physical contact with the source or target machines is required to run so that flexibility, the consolidation of all. Similarly, the next moveLama-generation hardware, rack or built without SMP server time.
Restore with backup products can be time consuming and involves the construction of new servers manually, install applications and restore data from tape or images inflexible. PlateSpin PowerConvert for Recovery is designed to completely reproduce a server for streaming over the network at regular intervals for any available physical or virtual machine, which could be used as a stand-by mode.
Live transmission capabilitiesallows for migration to be performed without the line source server. In case of failure of the main server, the standby system is activated to quickly take the load of work and resume normal processing. This is a very useful device, but I still think you should be very careful if you try this type of activity. PlateSpin offers a wide range of platforms through its various instruments are not supported. I think it's the widest range of all the P2V tools. Virtual machines runningPicture ® backup system input or solutions of VMware Infrastructure 3 VMware ® ESX Server 2.1 and later input or VMware ® Server 2005 and Microsoft Virtual Server 2005 R2 or Windows NT Server (SP4, SP6a) or Windows 2000 Server, Windows 2000 Advanced Server oo Windows 2003 Server or Windows Server 2003 R2 or Windows XP Professional (SP2) or Redhat Linux (7.3, 8.0) or Red Hat Enterprise Linux (AS 3.0, ES 3.0) or SUSE Linux Enterprise (9) or Acronis ® True ® LiveStateTM ImageTM or Symantec orPlateSpin Flexible Image Packages Symantec ® GhostTM ooo volume of raw data ® ™ or Veritas Backup Exec or CA ARCserve r11 BrighStor Double-Take ® from Double-Take Software
Installed without an operating system for servers, you must use a boot CD, place some control on the server. In almost all other cases, PlateSpin is used remotely, and there is no need to go to the server at all.
Last P2V:
This is a free plugin that is used as part of a bootable CD. The most popular boot CDsBart PE. The easiest way to use last P2V, located on the Bart PE CD, along with Ghost or Acronis (or your favorite imaging software), and all other utilities that you think may be useful to install. Maybe we have a change of password, or a file manager, or what I think will be useful for the planned mission.
It is a product "off-ramp." This means that you have never installed anything on the server. Just boot from the CD and then the utility to create the image. Once youcreated the image, you can last P2V, to transfer it to a virtual server.
Curiously, this method is the P2V requires you to have a competent technician. More likely to be the case once you move from trade to free tools. You have to work harder when it's free.
I have not used this tool. I used Bart PE, and is one of the most useful tools out there RAMDisk free in nature. Mostly used by crackers to change the access server and the admin 'Password. I have a Bart PE CD with me anytime!
EZP2V:
As above. This tool is used with a Ramdisk, 'off-ramp "utilities such as Bart PE. This can only be used with Windows servers. You need an imaging tool, as a ghost, and you must include a plug-in VMWare.
Last P2V is a free plugin that you can clone a physical machine to a virtual machine and require the reconfiguration of the system needed to allow bootable.
Warning: You areneed to find a load of drivers and install this utility compatible with standard operating systems.
Bart PE is used as a platform for clones of Windows. If you want to clone other operating systems, you must use the live CD of Linux as a platform.
VMware Converter 3.0:
VMware Converter is a scalable enterprise-class migration tool that converts physical machines to VMware virtual machines. Using a mechanism based instant cloning, VMware Converterenables remote conversions without the source server during the conversion. I wondered how long it would take to find a VMWare P2V freebee. I just became aware, as was mentioned in a review of VMware Converter VMware Web site. Obviously I could not wait to try it.
VMware P2V Converter is a solution. It allows you to convert physical machines to VMware virtual machines with Windows. The Starter Edition is free, the EnterpriseEdition will be licensed as part of the support and subscription services with the VirtualCenter management. The Enterprise Edition allows multiple simultaneous conversions, while the Starter Edition can convert only one machine at a time. Another difference is that the Enterprise Edition supports cold cloning, ie, migration out of the car. Since the operating system from the source system is not running in a cold migration, the process of cloning is less prone to errors. To cold clone a physical machine, ishave to boot from Windows PE CD, run the VMware converter.
VMware Converter 3 is an easy to use wizard to guide you through the configuration of the conversion task. The first step is to decide what kind of conversion you are planning. There are five options:
physical machine Physically remote computer VMware Virtual Machine Microsoft Virtual Machine Symantec Backup Exec System Recovery (or Ghost 9 images) The fact that it is free is also a reason forthey use. But it is limited to Windows, although not necessarily in a bind, since most people use Windows servers in most data centers.
Virtuozzo
You will know if you've read my previous articles on the topic of Virtuozzo virtualization to offer a virtualization tool that partitions the operating system. This methodology is particularly suitable for P2V. You can move virtual servers between physical servers without disruption to end users to move or the need for costly storage capacity with VirtuozzoLinux 3.0. No SAN required. The "zero downtime migration" capability is one of several important new features in the latest version of Virtuozzo for Linux - the new model of management, optimized resource management and improved operating system support for improving the performance and automation.
SWsoft (Virtuozzo developer), also led Virtuozzo for Windows that adds a "physical to virtual" tool that allows easy migration from a dedicated physical serverupdated on a virtual server, improved performance and platform support.
I personally like Virtuozzo. This is a different approach to other tools and has the great advantage of requiring only a single operating license of the host system (this may change in future as a license from Microsoft catches).
XenEnterprise:
XenEnterprise virtualization is the most effective tool available. It 'true, it is paravirtualization and 35% more efficient than VMWare and 40% + more efficientMicrosoft Virtual Server.
XenEnterprise leverages the open source Xen kernel to deliver it to the virtual process. Then there is the possibility of Linux and Windows servers on the same hardware support, the provision of Intel hardware, the V-extension, and AMD hardware VT extensions.
Included in the product is a set of tools that is fully integrated P2V. From the browser itself, you can create a server image of a server operating system to another piece of hardware, andinstall in a virtual machine on the XenEnterprise host server. XenEnterprise includes the VM tools export, import and cloning. No additional tools or utilities are necessary. All you need is just the application of XenEnterprise virtualization.
Virtualization is not the answer to all ills data centers. It takes a little bit ugly. You can take the excessive use of your systems, replaced the hardware out faster than traditional servers, virtual server sprawl with the expansion, and when you restarta host, each guest operating system on the host.
