VMware, Inc. VMware’s desktop software runs on Microsoft Windows , Linux , and macOS , while its enterprise software hypervisor for servers, VMware ESXi , is a bare-metal hypervisor that runs directly on server hardware without requiring an additional underlying operating system.

For the first year, VMware operated in stealth mode , with roughly 20 employees by the end of On July 8, , after disappointing financial performance, the board of directors fired VMware co-founder, president and CEO Diane Greene , who was replaced by Paul Maritz , a retired year Microsoft veteran who was heading EMC’s cloud computing business unit.

On April 12, , VMware released an open-source platform-as-a-service system called Cloud Foundry , as well as a hosted version of the service.

In March , VMware announced the corporate spin-off of Pivotal Software , with General Electric making an investment in the company. The service is designed to function as an extension of its customer’s existing vSphere installations, with full compatibility with existing virtual machines virtualized with VMware software and tightly integrated networking.

The service is based on vCloud Director 5. It announced the acquisition Desktone in October In January , in anticipation of Dell ‘s acquisition of EMC, VMware announced a restructuring to reduce about positions, and some executives resigned. On September 8, , VMware announced the release of Workstation Now the latest case studies, demos, blogs, and architecture toolkits of VMware are available in one place.

In April , according to Glassdoor , VMware was ranked 3rd on the list of highest paying companies in the United States. On April 15, , Dell is reported to spin out remaining of its VMware stakes to shareholders and the two companies will continue to operate without major changes for at least five years. The lawsuit was dismissed by the court in July [] and Hellwig announced he would file an appeal. VMware’s most notable products are its hypervisors. VMware became well known for its first type 2 hypervisor known as GSX.

This product has since evolved into two hypervisor product lines: VMware’s type 1 hypervisors running directly on hardware and their hosted type 2 hypervisors.

VMware software provides a completely virtualized set of hardware to the guest operating system. The host provides pass-through drivers for guest USB, serial, and parallel devices. In this way, VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest.

In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. Alternatively, for enterprise servers, a feature called vMotion allows the migration of operational guest virtual machines between similar but separate hardware hosts sharing the same storage [] or, with vMotion Storage, separate storage can be used, too.

Each of these transitions is completely transparent to any users on the virtual machine at the time it is being migrated. VMware Workstation, Server, and ESX take a more optimized path to run target operating systems on the host than that of emulators such as Bochs which simulate the function of each CPU instruction on the target machine one-by-one, or that of dynamic recompilation which compiles blocks of machine-instructions the first time they execute, and then uses the translated code directly when the code runs subsequently Microsoft Virtual PC for macOS takes this approach.

VMware software does not emulate an instruction set for different hardware not physically present. This significantly boosts performance but can cause problems when moving virtual machine guests between hardware hosts using different instruction sets such as found in bit Intel and AMD CPUs , or between hardware hosts with a differing number of CPUs.

Software that is CPU agnostic can usually survive such a transition, unless it is agnostic by forking at startup, in which case, the software or the guest OS must be stopped before moving it, then restarted after the move. VMware’s products predate the virtualization extensions to the x86 instruction set, and do not require virtualization-enabled processors.

On newer processors, the hypervisor is now designed to take advantage of the extensions. However, unlike many other hypervisors, VMware still supports older processors. In such cases, it uses the CPU to run code directly whenever possible as, for example, when running user-mode and virtual mode code on x When direct execution cannot operate, such as with kernel-level and real-mode code, VMware products use binary translation BT to re-write the code dynamically.

The translated code gets stored in spare memory, typically at the end of the address space , which segmentation mechanisms can protect and make invisible. VMware’s approach avoids some of the difficulties of virtualization on xbased platforms. Virtual machines may deal with offending instructions by replacing them, or by simply running kernel code in user mode. Replacing instructions runs the risk that the code may fail to find the expected content if it reads itself; one cannot protect code against reading while allowing normal execution, and replacing in place becomes complicated.

Running the code unmodified in user mode will also fail, as most instructions which just read the machine state do not cause an exception and will betray the real state of the program, and certain instructions silently change behavior in user mode.

One must always rewrite, performing a simulation of the current program counter in the original location when necessary and notably remapping hardware code breakpoints. The VMware product line can also run different operating systems on a dual-boot system simultaneously by booting one partition natively while using the other as a guest within VMware Workstation. VMware ESXi , [] an enterprise software product, can deliver greater performance than the freeware VMware Server, due to lower system computational overhead.

VMware ESXi, as a “bare-metal” product, runs directly on the server hardware, allowing virtual servers to also use hardware more or less directly. The VMware Workspace Portal was a self-service app store for workspace management. Cite error: A list-defined reference named “earn” is not used in the content see the help page.
