The churn rate on both ends has been very high, and we really wanted to release our patches with Xen support, but we also didn't want to wait some unknown number of weeks more to release them - and we're actually looking for volunteers to help with the port if anyone is interested. What we are hoping for, in the end, is a Linux kernel with a clean virtualization interface, that is maintainable, does not slow hypervisor exploitation of new technologies, still offers all of the same performance advantages, works for the open source community, and allows hypervisor vendors of many creeds to benefit from cross-kernel binary compatibility.
