There are many considerations when selecting a hypervisor such as the performance, how mature the technology is, how it integrates with existing systems, the commercial implications and guest and functionality support. In our latest white paper, we put together a guide that sets out to help you select the most appropriate hypervisor.
Within the paper, we compared four major hypervisors – KVM, Xen, VMware and Hyper-V. Here is a snapshot of the hypervisors we reviewed and a bit about each:
KVM – a Linux based open source hypervisor. First introduced into the Linux kernel in February 2007, it is now a mature hypervisor and is probably the most widely deployed open source hypervisor in an open source environment. KVM is used in products such as Redhat Enterprise Virtualization (RHEV).
Xen – An open source hypervisor which originated in a 2003 Cambridge University research project. It runs on Linux (though being a Type 1 hypervisor, more properly one might say that its dom0 host runs on Linux, which in turn runs on Xen). It was originally supported by XenSource Inc, which was acquired by Citrix Inc in 2007.
VMware – is not a hypervisor, but the name of a company, VMware Inc. Our experience with VMware involves its vSphere product. vSphere uses VMware’s ESXi hypervisor. VMware’s hypervisor is very mature and extremely stable.
Hyper-V – Hyper-V is a commercial hypervisor provided by Microsoft. Whilst excellent for running Windows, being a hypervisor it will run any operating system supported by the hardware platform.
