Qemu vs VMware vSphere: What are the differences?

What is Qemu? A generic and open source machine emulator and virtualizer. When used as a machine emulator, it can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance When used as a virtualizer, it achieves near native performance by executing the guest code directly on the host CPU. it supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, it can virtualize x86, server and embedded PowerPC, 64-bit POWER, S390, 32-bit and 64-bit ARM, and MIPS guests..

What is VMware vSphere? Free bare-metal hypervisor that virtualizes servers so you can consolidate your applications on less hardware. vSphere is the world’s leading server virtualization platform. Run fewer servers and reduce capital and operating costs using VMware vSphere to build a cloud computing infrastructure.

Qemu and VMware vSphere can be primarily classified as "Virtualization Platform" tools.

Some of the features offered by Qemu are:

  • machine emulator and virtualizer

- dynamic translation

On the other hand, VMware vSphere provides the following key features:

  • Powerful Server Virtualization
  • Network Services
  • Efficient Storage

According to the StackShare community, VMware vSphere has a broader approval, being mentioned in 87 company stacks & 147 developers stacks; compared to Qemu, which is listed in 4 company stacks and 6 developer stacks.
