VirtIO is an attempt to create an OS, hypervisor-neutral and bus-independent virtual device system. The initial implementations were in KVM/Qemu, using PCI as a bus, and lguest (using a custom lguest bus). In 2009 a draft specification was published covering network, block and console devices, and features and devices have been added in a backwards compatible manner since then. Slowly, other systems have been implementing virtio compatible devices, including FreeBSD's bhyve.
In 2013, using OASIS as the standard organisation, a 1.0 standard is emerging. This talk will describe the changes which are happening: Our goal is to keep the good, discard the bad, and make the ugly optional. We'll also talk about everyone's favourite subject: performance, and where we're going in future. Rusty Russell
