What Is VMware?
VMware Inc. is a public company subsidiary of EMC Corporation headquartered in Palo Alto, California and development centers in Palo Alto, San Francisco, Cambridge, Massachusetts and Bangalore, India. Its products include marketing programs VMware Workstation, VMware Fusion and programs provided free VMware Server and VMware Player.
Some of these are available on both Windows platform, Linux and Mac OS X. The company’s flagship products are VMware ESX Server and VMware ESXi, no more software is to be installed on operating systems like Microsoft Windows or GNU Linux, but real operating systems can be installed directly on physical machines by which you can create and manage virtual machines to achieve real virtual server farm.
What Is VMware Player?
VMware Player is a freeware virtualization (virtual machine) manufactured by VMware, whose first version was released in December 2005. It is a component of the commercial software VMware Workstation, since it was released for free, has enabled many new users to approach virtualization technology as able to run any virtual machine image created earlier with the commercial versions of VMware products. Currently, many operating systems team developing choose to provide their testers, as well as ISO images, virtual installations also ready to run within the VMware software.
The program is available for 32 and 64-bit architecture of Windows and Linux operating systems.
VMWare Player Versions
- 1.0 – This is the first public release. The software was able to virtualize multiple operating systems Windows, the major Linux distributions and other less popular operating systems on a virtualized PCs with hard drives, optical disks, floppy disks, a variable amount of RAM (although constrained by the real memory the host PC), sound card, network card, video card and serial ports (including USB) and parallel. The limitation of VMware software can not create virtual machines were quickly bypassed by programs and websites are able to do so based on just a few clicks: this was definitely decisive contribution to facilitate the dissemination of the software.
- 2.0 – This major upgrade enriched the player several new features. The most stress was certainly support the new Windows Vista which was also introduced support for basic features DirectX also guest operating systems could take advantage of the fast USB 2.0 technology was introduced and shared folders that can be used after installing the operating system virtualization software called VMware Tools add: this feature for the first time offered the opportunity to guest host and guest operating systems to share a folder, and then to exchange files without complex simulated broadcasts on the local network. Packages for Windows 2.0.x series were the only ones to provide the player with the VMware Tools also generally provided only bundled with VMware Workstation. In terms of usability, this version was introduced a welcome screen that was able to start one of the last used virtual machines or download a ready VMware site.
- 2.5 – Together with the support of an increasing number of Linux distributions as guest and as host, was extended to the 3D-operations between hosts and guests (including shared folders) grew even faster. The package for Linux abandoned the format. Tar.gz established a set of installation scripts and text became an executable file (with the new extension. Bundle) has a nice graphical interface and advanced that it occupied the entire installation process. Also include the suspension of the virtual machine (which can freeze the system to close the software and then restore it later) became available on both Windows and Linux.
- 3.0 – The latest player offers support for new Windows 7 along with an expected news: finally the software can create virtual machines. The main window has been enriched with several tabs that allow you to speak on every little detail of virtual machines (like some time competitor VirtualBox software), including the ability to simulate a multi-monitor. In addition, you can now download VMware Tools for guest operating system simply by acting as a menu.
What Is VMware Workstation?
VMware Workstation is a software suite developed by VMware Inc. that allows you to run multiple operating systems in a virtual environment. The first advantage that you can see and understand logically the possibility to implement on a platform running Windows or Linux and related hardware, a number n of other virtual machines with different operating system.
Software of this kind are called virtual machine, virtual machines, a term that indicates the creation of one or more virtual environments on a single computer, provides a complete emulation of the hardware resources without damaging the machine and emulating native operating systems, including them different. You may think that the emulated operating system performance may be lower than that operating system if it were done “really” but in reality the benefits are comparable because the system is designed to run on multiprocessor machines: each virtual machine works with a core, or manage real-time on the basis of sharing and can thus achieve high performance (from native system).
VMware is able to emulate x86 (Intel or AMD Athlon Pentium1-4) and x86-64 (AMD Athlon 64 / Intel Xeon) and also emulates dual-core processors.
VMware is available for Microsoft Windows, GNU / Linux and Mac OS X. Provides the option during setup, and allows choosing whether to create a host-only subnet and subnet NAT.
VMware Server (formerly GSX Server) is a software based server virtualization, VMware Inc., a dependency of EMC Corporation. VMware released version 1.0 12 July 2006. The Server is a continuation of the GSX Server product line. VMware Server can create, edit and run virtual machines. It uses a client / server, allows remote access to virtual machines. Beyond the ability to run virtual machines created by other VMware products, it can run virtual machines created by Microsoft Virtual PC. VMware, Inc. makes freely available in the hope of an update to VMware ESX Server.
Users of VMware Server have the ability to create (and restore) snapshot of each virtual machine with their VMware Server environment. The product has a specific interface for cloning virtual machines such as VMware Workstation.
The Server version 1.0 supports only 32-bit editions of Windows Vista. The kernel’s driver for the 64-bit was digitally signed. So the 64-bit Vista prevented the installation. This problem has been fixed with version 2.0 for Vista Server supports the Windows Server 2008 kernel, so the drivers can be installed without problems.
Known problems of VMware Server, updated in August 2008, are:
- The VMware virtual machines do not support the Firewire interface.
- The older VMware virtual machines do not provide direct support for USB 2.0, but you can make visible the USB 2.0 host operating system such as USB 1.1 devices in the guest operating system. Workstation Version 6.0 added support for USB 2.0 devices.
- Server Version 2.0 includes direct support for USB 2.0
- The VMware virtual machines provide only experimental support for 3D hardware acceleration through the Direct3D 8 API from Microsoft. A video appeared on YouTube shows various 3D games that run under VMware Fusion and Mac OS X.
- * Only mice with 3 buttons work inside the guest operating system. The mouse with 5 buttons are not supported.
64-Bit Solaris 10 1 / 06 (Update 1) and Solaris 10 6 / 06 (Update 2) Crash-based systems like Intel Pentium M Merom, Conroe and Woodcrest. An article in the Sun Microsystems blog has published a workaround for this problem.
Trying to mount an NFS share from an instance of VMware Server wart can cause a permission-denied error. To resolve this problem, change the instance to use the VMware network bridge instead of the NAT. Bridge networks involve adding additional network adapter, while the NAT using VMware server to assign an instance of an IP address via a DHCP server or a static IP address. Another way to solve the problem of permission denied is to use port forwarding, but this is much more complex.
VMware Server can accept interrupts the CPU, making it difficult to time management. The NTP server should not be run under VMware.
