Well, after 12 years, it was about the time.
Better performance, versatility, and faster booting. Using identical hardware, KVM Linodes are much faster compared to Xen.
For example, in our UnixBench testing a KVM Linode scored 3x better than a Xen Linode. During a kernel compile, a KVM Linode completed 28% faster compared to a Xen Linode.
KVM has much less overhead than Xen, so now you will get the most out of our investment in high-end processors.KVM Linodes are, by default, paravirtualized, supporting the Virtio disk and network drivers. However, we also now support fully virtualized guests – which means you can run alternative operating systems like FreeBSD, BSD, Plan 9, or even Windows – using emulated hardware (PIIX IDE and e1000).
We’re also working on a graphical console (GISH?) which should be out in the next few weeks.
