virtio was developed by Rusty Russell in support of his own virtualization solution called lguest. This article begins with an introduction to paravirtualization and emulated devices, and then explores the details of virtio. The focus is on the virtio framework from the 2.6.30 kernel release. Linux is the hypervisor playground.

How tuning the kernel. What are the kernel options necessary or useful to use KVM, how to optimize or tune the kernel for the host or the guest ? In the case of paravirtualization, virtio is used as a driver of the guest kernel, and a QEMU / KVM backend of the host. Kernel for host

Kernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the Linux kernel mainline in kernel version 2.6.20, which was released on February 5, 2007.Developer(s): Open Virtualization Alliance (OVA)

Add Migration support. We rely on recently added gtree and qlist migration. Besides, we have to fixup end point <-> domain link. Indeed each domain has a list of endpoints attached to it.

With the VirtIO standard for cross-hypervisor compatibility of different virtualized components there is a virtual IOMMU device that is now backed by a working driver in the Linux 5.3 kernel. The VirtIO specification provides for a virtual IOMMU device as of the v0.8 specification that is platform agnostic and manages direct memory accesses from emulated or physical devices in an efficient manner.
