Xen support in the Linux kernel?

Much of the virtualization around Linux over the last couple of years has gone to KVM which has made it appear as if Xen is dead or dieing.

This is not true! The largest virtual infrastructure in the world uses Xen as a hypervisor – Amazon Web Services.

Now Xen is in the mainline code of the Linux kernel.

This is great and will bring more visibility to Xen.
