Linux With all the virtualization schemes running on top of Linux, how do they exploit the underlying kernel for I/O virtualization? The answer is virtio, which provides an efficient abstraction for hypervisors and a common set of I/O virtualization drivers. Discover virtio, and learn why Linux will soon be the hypervisor of choice.

On x86(_64), VMware ESX(i) is. While it uses driver code from Linux and even uses Linux for the ESX service console, the hypervisor is definitely not Linux.

Xen is probably the most popular non-VMware hypervsior; although Linux is commonly ran as the privileged guest (aka dom0, which handles I/O), the Xen hypervisor is separate from Linux (and other operating systems such as Solaris can act as the dom0).

Hyper-V, Microsoft's hypervisor, is also not Linux.
